10 Worst Items Ever Tested? Let’s Find Out!

In all videos on this channel, our viewers suggested. I've gotten a lot of requests to do a review of the 10

worst

products

ever

tested

, so let's do it if you're looking to save a few bucks on a power tool battery. You may decide to buy a knockoff battery and you may simply regret that decision. I compared s

ever

al imitation 6 batteries, including the amti battery, to a genuine Milwaukee 6 per hour battery and the first sign that things were not going to go too well for the emti is the weight of the battery and the emti alone It weighed 596 G and the genuine Milwaukee is much heavier at 1077 G.

How on earth is an imitation going to perform as well as a much larger and heavier battery to compare batteries? i bought a 175 watt milwaukee power supply, each of the batteries ran a fan that draws about 150 watts and the $26 emti claims to deliver 6 amp hours and that's a very good price if it can really deliver that much power, unfortunately the emti ran out of juice and only 15 minutes and 51 seconds i used the genuine milwaukee battery as a litmus test and the genuine milwaukee was barely warming up at 15 minutes to 23 minutes the milwaukee still has a lot more juice to give and the milwaukee genuine is still smiling at 32 minutes and a 6 amp hour Milwaukee finally ran out of power at 39 minutes and 15 seconds, so the Milwaukee lasted more than twice as long as a yti, the 6 amp Milwaukee outperformed all the imitations and the amti finished in last place among all. batteries and knockoffs, but things were about to get much worse for the amti.

A battery operated tool is only as good as a battery so I compared the batteries using a Milwaukee drill and a hog adapter inserting a lag screw and Milwaukee made very quick work of the 5 inch lag screws and got to 183 inches and the battery emti gave up very early at only 89 inches, which is less than half that of the Milwaukee, so once again the Milwaukee 6 amp hour battery finished in first place. on the emti i finished last once again, then i use an impact driver to compare the performance of each battery driving with three lag screws per battery, any emti really struggled driving with the lag screws averaging over 7 seconds per bolt and the genuine Milwaukee went in three leg bolts without any problems and an average of 6 seconds per bolt and once again the genuine Milwaukee came out victorious and the emti once again finished last an angle grinder is a very thirsty tool and the emitter is really struggling and it's hard to believe but the emitter already gave up in just 10 seconds and I can't turn the grinder back on and the genuine Milwaukee battery lasted over 6 and a half minutes and made great progress sanding the paint. of the metal and once again the emti finished last if you don't want your house or shop to burn down it is a very good idea to have batteries that are short circuit protected to test the short circuit protection of the batteries.

I use two metal ones. Conductors connected to the positive and negative contacts of the battery. I also used the current meter to track the peak power and duration once the battery expires and the emissions reached 123 amps and the current is gradually dropping and the current. finally it dropped to zero in almost 8 seconds it is definitely not a safe battery in my opinion so the emti offers less than half the battery capacity and in my opinion it is also a very unsafe battery definitely one of the 10

worst

products I have

tested

and the ZSP jack stands definitely earned a spot on the list of top 10 worst products ever tested.

If you ever crawl under a vehicle, your safety and your life depend on jack stands doing their job. The manufacturer claims that it is a six-ton ​​adjustable performance jack stand for cars and trucks. and the manufacturer claims that this jack stand is as stable as a rock and i'm not kidding, these things seem terribly unsafe and the zsp is a set of extremely lightweight jack stands with very poor build quality. I also measured the outside lateral movement of the center tube and the zsp has the most lateral movement of all brands at 3/4 inch and in the first test I measured the amount of force it takes to make a vehicle fall off the stands of the cat.

Most jack stands performed very well with over 180 pounds of force before the jack stands fell off and the ZSP claims to be rock stable. 95 pounds of lateral force definitely the most dangerous jack stands I have ever seen. I tried all the jack stands and several additional tests and all the jack stands besides the zsp survived the test. Most jack stands took over 20,000 lbs to crush in a controlled downward direction. I repaired the zsp and tested it one more time and torques were flying out of the zsp at around 5,000 lbs. It took over 40,000 lbs to crush the jack stand.

The American Jack is very happy with his performance and the big red also showed himself. some pretty impressive dance moves, but not the zsp. There are many other high quality jacks that stand out, but I recommend avoiding the zsp. A battery with a name like Ultra fire definitely seems doomed to be on the top 10 list, it definitely seems like a name. This indicates that the battery has a quality problem. 18650 batteries are used in all types of devices, including headlamps, portable fans, and even tool batteries. The manufacturer rates the Ultra Fire at an impressive 9,800 Mah hours, the first sign that the Ultra Fire was in trouble.

It was when it got on the scale and it only weighed a little more than 35 G, on the other hand the Panasonic only has a power of 3500 mah and it weighed 12 G more than the ultra fire. In the first test I compared the internal resistance of the internal batteries . Resistance is the opposition to the flow of current within the battery after the batteries are fully charged. The two Ultra Fire batteries I tested had an internal resistance of 48 and 31 respectively. It is not good. I tried a couple of Samsung batteries and they had much better internal resistance.

At only 11.7 inches we definitely want the internal resistance to be low. I then used a battery tester to measure the actual capacity of the batteries and the two ultra fire batteries I tested were supposed to produce 9,800 Mah and they only had a capacity of 1,230 and 1,163 looking at the actual weight, the ultra fire batteries were very light in comparison to brands like samsung lg sony and panasonic when it comes to being honest about its capability its a liar a liar pants on fire for the ultra fire the ultra fire just delivered. 12.2% of its rated capacity, the worst in The Showdown to compare performance in cold temperatures.

I then tested the batteries at around 6°F once again, the ultra fire really struggled at only 12.5% ​​of its rating, the LG, Samsung, Sony and Panasonic brands all performed excellently. better, ranging between around 90% and 100% of your rating. I then compared the performance of the batteries under a light to moderate current load ranging from 1 to 10 amps; At just 1 amp, the ultrafire voltage dropped to just over 4 volts at a very low rate. small charge of 2 amps the ultra fire was already starting to have problems with only 3.8 volts at 5 amps the ultra fire was almost ready to throw in the towel at 3.27 volts and it was over for the ultra fire at 6 amps at only 1.66 volts I then installed the batteries and fans to compare the run time and the ultra fire lasted 102 minutes;

On the other hand, the Japanese and Korean batteries lasted more than twice as long considering the 9,800 milliamp rating and terrible performance the Ultra Fire definitely deserves to be on the market. Top 10 Worst Products List The next product to make the top 10 worst products list is this HHO or oxyhydrogen generator. The manufacturer claims that it can reduce fuel consumption by up to 35%. It also claims to reduce emissions and extend engine life. It even claims to increase the engine. torque and improve acceleration You can have all this capability for about $200 The kit comes with a dry cell hydrogen generator a pair of rubber hoses and a holding tank for water and electrolyte solution It also comes with a bubbler electrical wires and connectors The water container is supposed to send water to the hydrogen generator, then the hydrogen generator produces a gas which returns to the water container.

By the way, this gas that returns to the container is highly explosive. From the water container, the gas goes to the bubbler and then to the engine. There is quite a bit of electrical and plumbing work that needs to be done to make this kit work. This includes permanently altering some things under the engine compartment, such as drilling a hole in the air intake assembly. There is a relay that turns on the HHO unit while the vehicle. is in use In addition to purchasing the kit, you will also need to purchase some potassium hydroxide for the electrolyte solution after installing the kit.

I inspected the spark plugs in the combustion chamber for carbon buildup before starting the HHO generator. I did a couple of 0-60 MPH runs after doing two runs without the HHO connected. I installed the fuse in the HHO setting and the HHO kit is working properly and there are bubbles going to the engine. I did a couple of 0-60 runs with the Unfortunately, with HHO engaged the vehicle showed no improvement in performance and in fact was a little slower from 0-60 MPH, no improvement with acceleration but I was hoping to see a cleaner spark plug or combustion chamber, unfortunately there was no noticeable improvement.

Then I tested the fuel efficiency. Using a fuel injection generator, the generator had to supply electrical power to the H kit. The generator ran for 19 minutes and 46 seconds before installing the HHO kit. After installing the kit the generator ran fine, unfortunately the generator did not show any improvement in fuel efficiency. In fact, the engine only ran for 19 minutes and 36 seconds, or 10 seconds less with the HHO setup installed. I then tried the H generator a second time to see if we saw any improvement. This time the HHO setup performed a little worse at 19 minutes and 25 seconds, so the HHO kit didn't live up to any of the claims and is a waste of money in my opinion.

For just $19, you can turn your drill into a circular saw. Unfortunately, the circular saw can also function as an angle grinder. The saw doesn't come with assembly instructions, but it's pretty simple to assemble a few nuts and bolts in about 5 minutes of assembly and the circular saw is ready for action. The construction seems very lightweight, but again the cost is under $20. You can even cut at an angle, the maximum cutting depth is about an inch. Made in China for comparison. First let's make a cut through 1 inch oak using a 1,000 inch cordless circular saw. 1.3 seconds to make the cut as a right-handed person holding the drill with your left hand and holding the saw with your right seems a little awkward and the circular saw vibrates quite a bit and seems quite incomplete to say the least, the cut made by the accessory is on the bottom and the Milwaukee saw is on the top and it's a much smoother cut with the Milwaukee saw and there's quite a bit of wobble with the output shaft in the blade.

Not all drill accessories are junk. This Malco metal cutting shear did an amazing job cutting sheet metal. The Malco shears did very well. easy job of cutting aluminum flashing, also did a great job cutting 20 gauge steel, on the other hand, the M ment attached circular saw is more likely to cause an injury than making a quality cut, definitely one of the worst products . I have ever tried that an angle grinder can be adapted to many different things, but this drill attachment is extremely dangerous at a price of only $12. It may be very tempting to buy this angle grinder drill attachment.

It claims to have a JW three chuck that has a firm hold. Made of high carbon steel, unfortunately I don't have an angle grinder that has a 10mm spindle. I have quite a few angle grinders and they all have 5 hns spindles so I have an adapter that needs to be adapted to work with the grinder I will also use a 5/8 inch grade 8 nut to serve as a coupler a typical drill rotates 2 to 3000 RPM, however a grinder spins about three times as fast, unfortunately there is too much wobble due to things being out of alignment. I definitely had a very rocky start.

Fortunately, I bought a 4 inch angle grinder locally that has 10mm threads, but the angle grinder has the wrong thread pitch, so I will have to use a tap to reshape the threads. This is definitely not a perfect solution, but it will get the job done the way you like it.say primo edti, good enough for government work and the chuck appears perfectly aligned with the angle grinder shaft. Let's see how it works either way drilling a 2x4 with a 38 inch drill bit and the angle grinder drill attachment is time consuming and made a very quick job of drilling through the 2x4 to keep the drill from moving.

I will make a slit in the plank/quinch. I'm going to go ahead and use a cobalt split tip. Twist drill bit. I applied a lot of downward force to prevent the bit from hardening the mild steel and it only took 3.6 seconds to drill the hole and 10,000 RPM for a drill is too fast, while most angle grinder attachments were sketchy. Actually, there are some good accessories like this belt sander, it has a unique design that allows you to sand curved objects like pipes, while there are some good angle grinder accessories. I highly recommend avoiding dangerous ones like this drill adapter, the next product to earn a spot on this terrible list is the Performance Tool 38 in Ratchet.

The $7 price is the first clue that this ratchet might have a performance issue. However, we

find

affordable products that work great every time. Manufacturers sell ratchets using marketing information about Arc swing. and Tooth Camp, are trying to convince you that their ratchet is better for working in a tight space, so I compared all the ratchets that work within a 30° and 30° space and the Performance Tools gear set is extremely sloppy and can only advance one tooth at a time within a 30° gap and the ratchet really struggled in this test and it took 39 right to left movements to finally complete 1 360° rotation.

On the other hand, the 0-degree gear wrench in the Pro icon completed the test in less than half the round-trip passes and a performance tool finished last in this category, a ratchet with a lot of forward drag. back really makes removing and installing screws faster and tight spaces a challenge at times if there is enough room to add strength to the socket using finger pressure. allows the ratchet to advance, but that is not always an option for this test. I used the 7/8 ferrule fishing line on a scale to measure rear drag and a performance tool once again had trouble with 698 G of rear drag, other affordable ratchets Like the S, it has less than half of the amount of back drag, a high performance ratchet will perform well in both the bow sway test and the back drag test, while the Performance Tool did not finish in last place in this test, it did finish in the last three.

If you have greasy hands, a stiff directional lever can make things very difficult. I measured the performance of the directional lever using a scale, screwdriver, and a Performance Tool ratchet which I finished last in this test with 1,561 G or about 3 and 2 pounds of shifting force. instructions In a final test, I compared the failure load of all the ratchets. This is a 3-inch ratchet and should easily handle 200 foot-pounds of force and the Buttery Soft Performance Tool ratchet is all bent and warped at just 58.4 3 foot-pounds per glance. inside the ratchet and there is a lot of damage and all the ratchets exceeded 200 tons of torque except Performance Tool and a ratchet from Performance Tool just proved that the only thing it will loosen is money from your wallet, definitely the worst ratchet I have.

I've tried it before and Performance Tool has the distinction of being the only brand with two products listed. Unfortunately, the Performance Tool bowl cutters are absolutely terrible. However, this time the Performance Tool bowl cutters are not the least expensive product, in fact, the Genford bowl cutters cost. $3 less so I tried the genford brand first in the first test where the Bol cutters competed to see which brand can make the easiest job of cutting a 16 cent nail. I put together a tester that holds the cutters and nail and also measures down. Force was applied to the handle, locking pliers held the end of the nail to prevent it from becoming a projectile, and the very affordable Genford brand made the cut with 120 pounds of tight force.

The good news is that the Performance Tool barely edged out Genford. In the first test with 114 pounds as a benchmark, the more expensive Kab Tool bolt cutters made the nail very easy and about half the strength with only 61 pounds of compression force on the handle. Very impressive, the German made Knipex brand did almost the same thing, at 62lbs, these are bulk cutters and a 16 cent nail is not even a challenge for a good set of bulk cutters, so let's stop going around and We tested the bolt cutters on a deck screw and it took a lot of force to tighten. for the $7 jred bolt cutters to make the cut with 166 lbs, but survived the test with minimal damage to the cutting blades, unfortunately the deck screw outperformed as tool bolt cutters, the deck screw held well, but the lower jaw of the Performance Tool bolt cutters bent a lot with 164 lbs of force on the handle as a pointy reference, cpre tools easily cut the deck screw with only 89 lbs of force, very awesome and the cutting knives still look great and the kip the only brand that did not survive cutting the deck bolt while evaluating where it is highly subjective all brands receive a damage rating of one or two, indicating very little or only minor damage, except Performance bolt cutters Tool that cuts a 3/16 inch drill bit.

Now we are finally entering the territory of bulk cutters and high quality bulk cutters like those made by Ares. The cutter at only 166lbs and the cutting blades are still in good shape as are the Ares. The compression tooling made the bit very easy to work with at only 134 pounds, so the very hard bit eliminated five extra marks and none of the cutters had a chance to survive a hex wrench, but it gave us its load. of failure and the top brands in the line exceeded 300 lbs of handle force, but Performance Tool finished last and the next brand to make the list of worst tools is a Shop Tech SE clamp, but the tool brand from performance came in second place.

The advertised capacity for each of the C clamps is 6 at Shoptech has a ductile cast iron frame. The actual capacity is only 5 and 5/8 draft capacity makes a difference. in being able to reach and then apply force to the correct part of the workpiece and the shoptech simply doesn't offer much reach at just 2.25 inches when trying to hold two objects together, a set screw with too much slope can make a workpiece of work moves out of position and a cut has 0.095 inches of movement, handle length, thread pitch and build quality are very significant. Some of the C clamps are actually lightweight to standardize the amount of handle force applied to the EC clamp.

I prepared this fixture that allows torque to be applied to each screw handle equally. I have a click style torque wrench that I'm going to go ahead and set to just 50 inches and then use that to test each of the C clamps, the Shop Teex adjusting screw. it's quite gritty and not at all soft with 50 lb-in of torque at the handle, the shoptech finishes at 396 lb clamping Force, the Performance Tool clamp has much steeper at 8.5mm or about twice as much as any of the other brands and the Performance Tools set screw is very gritty and only came in at 282 lbs to take the last position of the shoptech applying an equal amount of leverage to all C-clamps.

The top performing brands delivered over 1,000 lbs of clamping force and shoptech ran. no force at 396 lb and Performance Tool 282 lb, so for now Shoptech is actually outperforming Performance Tool and Performance Tool also finished last for adjusting the screw slot, but the competition is not about a jam or a stub and the rotating head causes the workpiece or clamp to move a little when trying to tighten the C clamp to test the build quality of the rotating heads. I will place this ball transfer unit under the iron so it spins freely. Then I will apply 500 lbs. of clamping force on the swivel head and the Shoptech swivel head is stuck and a swivel head slides on metal at 56 inches to 2.5 inches from the fulcrum and a performance tool finally outperformed a shop technician with 25 pounds, but there is a lot more competition. remains in this showdown and it is a big relief for the Performance Tool brand as a shoptech finished last in this event when I can't get enough clamping force just by using hand strength on the handle, a cheetah bar really help so let's see how much strength we can get before bending the handle and the shop tech got to 812 lbs before the handle bent and the Performance tool ran out of performance at 1,416 lbs and didn't go down quietly, the handle now It is folded afterwards.

Yet another round of competition, the Performance Tool SE clamp is starting to distance itself from the shoptech, but the competition doesn't end if a clamp is already under-loaded, let's see how much clamping force each brand can offer before experiencing damage and the shoptech opted for two different. instructions at 980 lbs., the Performance Tools set screw doesn't offer much clamping load, but the frame has pretty good strength at almost 4,000 2,200 lbs. After a pretty rocky start, the Performance Tools brand rebounded nicely , but shoptech didn't and shoptech finished a very distant last place to round out the bottom 10 list, diagonal cutters made by Illinois Industrial Tools made the list.

It's a good thing Performance Tool didn't compete in this event because of the way Illinois Industrial Tools diagonal cutters are made in China. and not Illinois, the first sign of problems for Illinois industrial cutters is that the shaft joint is extremely loose when there is enough wobble, the cutters do not align and you get very inconsistent results; The average person can exert a compressive force of around 100 lbs just like the bulk cutter review. I will use the same tester to compare diagonal cutters in the first test we cut 16 penny nails, you will need a very strong hand or you will probably need to use two hands to cut a 16 penny nail with the Illinois Industrial Tools diagonal cutters that weigh 195 lbs.

It may be tempting to think that you have to spend a lot on performance, but for less than $20 you can buy Irwin diagonal cutters and you won't need to buy any cans to cut. through a super soft nail and the Irwin made the cut at just 78 pounds compared to 195 for the Illinois Industrial Diagonal Cutters, just like the Irwin, the $21 Channel Lock Diagonal Cutters made this look like Too easy at only 73lbs from 15 brands. Industrial brand Illinois is in last place after the first round of competition. Nails are very soft compared to screws, so let's see how the cutters on a deck screw compare.

Unfortunately, Illinois industrial tools couldn't make the cut and the pliers gave up. 342 pounds of force are used on the diagonal cutters, but the deck screw is still in good shape. These are diagonal cutters and not both cutters, so let's see if any of the brands could survive cutting a bit and the very affordable Irwin cutters made the cut. At only 191lbs and the cutting blades are still in good condition, surprisingly over half of the marks survived the bit. I then used the shaft of a bushing adapter to measure the failure load of the rest of the brands and one of the Irwin jaws broke. at 320 lbs and the cutting knives still look sharp, all the diagonal cutters did a better job cutting nails, screws and bits than the Illinois industrial tool brand and they all had a higher failure load, worst 10 products, obviously , I don't accept them. sponsorships and buy everything tested on the channel, all videos on this channel are suggested by viewers, so if you have an idea for a video, I hope you take the time to leave a comment.

Thank you very much for watching, be careful and wait for the next time.
