Wagan EL2257 12V DC Mighty Impact Wrench, 1/2 inch 12 Volt Electric Impact Wrench Kit, 271 ft-lbs, Tire Repair Tools with Sockets and Carry Case

Must to have on the road Like a big brand tool, solid, strong, doing the job great. Being electric, works some kind different as the air compressed we found on any car shop

Value is great

I've had this six years. Only used it a handful of times. When I went to use it today, it wouldn't work. The light was on, but no action. I changed the fuse. Still not working. Also, with the way it is stored in its container, the bend of the cord from the handle end exposes the wires within. A shame. It did work fine when it did work. UPDATE: August 2nd. I took the thing apart. The problem was, a wire had come loose inside. I inserted the wire, firmly, back into position. Put it back together, and it worked fine.

I only tried it once as a test, so I can't comment on the long-term durability or maximum torque. But it worked as advertised out of the box, and easily and quickly took off lug nuts tightened to 76 ftl-bs with two impacts. Putting the nuts back on, two impacts tightened them to exactly 76 ft-lbs as well. Overall it seems well-enough made, though not heavy/commercial grade. But it definitely seems sturdy enough for occasional or emergency use. Which what got me looking in the first place. After getting a flat and being unable to remove even a single nut with a standard wrench (even hammering it!), the AAA guy showed up and used a similar device to have all the nuts off in seconds. And with this there is strain on your back!

The device works, but not as effective as I would like. This 12V impact wrench best operated with car running to supply 14V to make this product work better. At one impact per second or so, it takes a few seconds to wack wheel nut loose. Bottom line, it works, but for practical reasons, if it takes time to deal with the cable and its hookup, and throw in the one impact per second operation, it is just too much fuss with little reward. Better to have a breaker bar and appropriate lug nut size socket to leave in car for more efficiency. The short ineffective lug wrench supplied with most cars easily compensated by a good long Craftsman breaker bar with appropriate socket. With no assurance of how tight the lugs are when reinstalling them, a real wrench is best used anyway after using this impact wrench. However, the item is a keeper for me as home mechanic to deal with certain suspension work and long reach hardware. I would not recommend this product to the average buyer eyeing this product as an alternative to normal methods. 6/2012: Now comes a positive update. The tool is very useful when time comes to perform car maintenance beyond working at one wheel. When rotating tires, this impact wrench amplifies its advantage compared to single wheel work scenario. Rotating tires or removing multple wheels to perform brake work are times when this tool really shines. There is the need to use a breaker bar or torque wrench to tighten the lugs with proper torque. Counting number of impacts during tightening process may not generate consistent tightening torque from lug to lug. But this tool works!

Finally had a chance to use this. Worked exceptionally well. Definently recommend. Easier then wrenching .

How to use this Impact wrench!!! I learned a lesson today, the impact wrench WILL NOT WORK work if you PUSH into the bolt you are trying to remove!!!! Instead put the socket on the bolt securely, then squeeze the trigger. The unit will spin up then go clank!, To remove my tire lug, I had repeat this 6x but each time I saw the lug turning. NOTE: if you use this on a flat, clank it 3x per lug then jack your car up a bit so the tire is either on the ground lightly or above ground or use your tire lug wrench again with the tire off the ground. If you have the weight of the car on the flat tire, you could snap or bend the lug nuts and or damage your rim!!! This supposedly has about 100lb more torque than the Kawasaki which I purchased first, and I think it does have some extra power as the Kaw. did not loosen my lug at all, BTW I also noticed I pushed the wrench into my bolt for some reason and I thought I broke it.... Moral of the story, put the socket on the bolt/lug but do not push into or down into the lug/bolt. I learned the pushing stops it by trying to remove the bolt on my motorcycle fork (if you need to replace your seals this makes it a piece of cake)! I pushed down and nothing was happening, luckily I took pressure off and then it worked, that's how I figured it out!!! I bet most of the I didn't work people made the same mistake as I just returned the Kawasaki for the same reason!!!

I bought it because this was the least expensive option and came with additional sizers. I used it on my sedan and it struggled at first to take the lug nuts off but it did work. It gets hot faster, the quality ( for which I took few stars off) is marginal at best. I don’t anticipate it lasting with regular use. The built in light feature seems useless as well. Its Avery did light poorly placed at the bottom. I kept it because it does work and only for emergency use.
