Review: Works great! - Perfect piece of equipment Review: Solid. - Its heavy, but all metal construction so that's a good trade-off for durability. I like the placement of the forward/reverse switch... this is more ergonomic than other Ingersoll-rand designs I've used in the past. Its surprisingly quiet... didn't feel the need to use any ear protection... which I almost always use with air tools in general. Used this tool with a tiny porter-cable compressor rated for 2.6 CFM with a 6 gallon tank. It worked pretty good taking lugs nuts of my car wheels.... All but maybe 3 lug nuts out of 20 came off with ease... Not surprising, a few did not as this is a tiny compressor for this type of tool so its to be expected to have some performance gaps... but overall I am pleased. I specifically picked this gun for the low CFM rating because I intended to use it with a small compressor. Using this tool was a huge time saver despite the 3 lug nuts that were stuck. No doubt a larger compressor would have over come that issue but good enough for my needs. ## Features - Metal / Plastic - Imported - Speed and Power: With a maximum torque of 425 ft-lbs (576 Nm) in reverse, this impact wrench delivers impressive power for fastening and loosening tasks.
