Rated 3.6 out of 5 by 13 reviewers.
Rated 4.0 out of 5.0 by Good buy for the price I am a professional Technician at a reputable Dealership. I have Snap On,Ingersol Rand and Aircat air tools. I bought this as a back up ratchet. It has more than enough power to get the job done. Many brand name air tools including the ones I own are all rated higher than what they will actually produce. So if you think this ratchet isn't up to snuff hook it up to commercial grade compressor and hold on. It performs just as well as many name brand ratchets for a lot less money. November 23, 2011
Rated 5.0 out of 5.0 by Strong, durable tool for the price I've been using this tool for about a year, and its by far the strongest, smoothest ratchet I have used in a long long time. Love it. Highly recommended. Pairs nicely with my now discontinued Husky Pro 60 Gal air compressor. January 22, 2012
Rated 5.0 out of 5.0 by Great wrench Got a good deal on this wrench I wasn't sure of the Husky name but I'am now. This wrench has power,well built and strong.It's easy to control speed and direction and feels good in your hand. The only bad thing is I've gone without one for so long I wish I had this wrench years ago what a time saver. July 9, 2013
Rated 4.0 out of 5.0 by Best torque for the price This is a solidly built tool with the best torque for the money. I would recommend this for the shade tree mechanic,but I don't know how it would hold up for a pro. At the price,it would definitely be worth a try anyway. June 25, 2013
Rated 4.0 out of 5.0 by Very good air wrench with good power I bought this air wrench as a clearance item and was very pleased with the amount of torque it produces. The only drawback was that it is louder than my last air wrench, which was also a Husky, but could not be repaired. June 5, 2013
Rated 5.0 out of 5.0 by This product works great It has made my repairs alot easier? It's lightweight and durable. February 14, 2012
Rated 4.0 out of 5.0 by Easy to use. good torque for the size This Huskey 3/8 ratchet is built strong. It is very easy to use. August 13, 2013
Rated 1.0 out of 5.0 by Constantly leaks air I just bought this and am bringing it back. When hooked up to my air supply there is a constant stream of air coming from the pin holding the trigger to the wrench. Also, when the trigger is depressed you get a spray of oil coming out around the body of the barrel between the metal and rubber grip. No wonder it's only $30... August 5, 2013
