Review on KIMO 20V Cordless Impact Wrench Kit - 1/2" High Torque, 3000 In-Lbs & RPM, Battery Driver With Fast Charger LED Light 7 Sockets by David Hashman

I use this Kimo impact wrench to help swap out all 4 wheels on my car. 20 bolts in total, each one torqued to 118 lb/ft. The Kimo removes them all with few problems. In the past I used a breaker bar to loosen the bolts and then my impact driver (Bosch) with a socket bit to unscrew them all the way off. With the Kimo it is all one step, and without the manual effort needed to work the breaker bar. Usually there are a few stubborn bolts that the Kimo can't loosen right away, it might take 2 or 3 tries. But it will get them all off.I only use it for loosening bolts. I still use the Bosch to screw the bolts back on, at a very low setting, then manually tighten with a torque wrench to get them back to exactly 118. I'm sure the Kimo could get them on tight but there would be no way to be precise and no way to prevent over-torquing.The Kimo is the only impact wrench I've ever used so I can't really compare, but it works perfectly for my use. It's loud -- that's the wrench repeatedly hammering the bolt to loosen it. It uses a retaining pin and o-ring rather than a detent ball -- I think if I were switching sockets often I'd prefer the ball. Battery easily handles this job. I would suggest bringing your own sockets and not relying on the ones in the box.Overall very happy with this purchase, it has made the job much easier, and I would not hesitate to buy another Kimo tool.
