Rated 5 out of 5 by 1/2 air impact wrench Works great. It will break bolts if your not carefull October 28, 2014
Rated 1 out of 5 by junk I lived with gun for about a year, the switch would not work. I had to tap it to get it to switch from forward to reverse. I tried it on my friends compressor thinking I did not have enough air ,no good . I bought a new 60 gal compressor thought now I got enough power, still did not work right. Well last night it finally broke on the end where the fitting goes in, now I can go by a real impact wrench. Not a Husky June 18, 2014

Rated 5 out of 5 by Perfect impact for the homeowner. Breaking those tight bolts on my zero-turn mower blades was easy with this impact. I am very pleased with it. If it holds up over the years, it will turn out to be a BARGAIN! July 8, 2014
