Craftsman 1/2 in. Heavy Duty Impact Wrench —
I read all the reviews, did my research and purchased a few different impact wrenches (with the features I needed) in the $100- $200 range to try. This one performed the best and was the best buy for the money. There is no air leaks as other reviews complained about so if this was a problem it's probably been corrected. It is lightweight, compact , has a comfortable grip, quiet, very powerful and well made. Much nicer than more expensive units I tried including the Sears Professional model at $179.99 which is bulky. I have the Sears Professional 150 PSI/25 gal. oil lubed 120V compressor which provides plenty of air supply for this gun. I even torqued a lug nut as tight as I could with a breaker bar and this gun took it right off in 2 seconds. I recommend it as do the guys at my local Sears tire shop who also use it..
