This tool worked great with a 12 gallon 6 cfm at 90 PSI air compressor. Easily removed lug nuts and rusted VW axle nuts. Struggled with an old front wheel bearing, but still worked. Seems very well made and hopefully will last me for years.

I bought this impact to work on my personal vehicles at home but, out of curiosity, I took this impact wrench to my work before heading home with it to see how well it would perform. I work for a trucking company that has its own shop. I gave this impact to one of our mechanics, who in turn removed a lug nut from a big truck. This impact spun the lug nut off in about a second or 2 with no problem. He then put the impact on its highest forward setting and put the lug nut back on. After the lug nut was as tight as he could get it with the impact he checked the torque with a torque wrench made for torquing big truck lug nuts. The torque wrench is set at 475 foot pounds of torque and only put about another 1/8 of a turn on the lug nut before clicking.... That's some pretty impressive power for $80 and more than enough power for what most people would ever need working on their own personal vehicles. The warranty on this impact (3 years) is great as well. Most other impacts, many of which cost 3 to 4 tines the price, only come with a 1 year warranty. The cfm rating is also very low for an impact in the sub $100 range. 3.9 cfm is almost unheard of in this price range. Most of the brands I have looked at below $100 were at 5.0 cfm or more. This means that you don't have to have a big expensive air compressor for this tool to work, although you do still need one that puts out at least 3.9 cfm @ 90 psi to get the full power from the tool. You will also need a 3/8 air line at the minimum. The 1/4 pig tail lines that come with some of the cheaper air compressors will not provide the tool with enough air flow for it function properly. One downside, if you want to call it that, is that this impact is pretty heavy compared to some of the more pricier brands, weighing in at just under 6 pounds. This isn't a problem for me but I thought I would mention it. In summary, if you are looking for a solid, powerful, impact under $100, you won't be disappointed with the Bosch. Just make sure you have a compressor that put out enough cfm and a good air line.
I am not a huge handy person but I know when a power tool is good by its...Power! When I first hit the button, I was actually a little scared at first. This tool is extremely versatile for projects as big as fixing up your car to little things like filling air in your tires. Highly recommended!
I have 6 gallon 2.6 cfm compressor @ 90 PSI, and it worked fine. Compressor turns on after getting one wheel of lugs off, but no biggie to me. Was tough at first getting brake rotor bracket off, but turned up PSI to 110 like someone suggested, and came right off. For the do it yourself mechanic that doesn't use it often and is patience when compressor kicks on, I think it is fine.
