Review on Powerful 12V DC Electric Impact Wrench Kit - Wagan Mighty Impact Wrench With 1/2 Inch Drive And 271 Ft-Lbs Torque, Including Sockets And Carry Case For Tire Repair Tools by Nuntawat Bridges

I bought this impact wrench thinking that it would work like a pneumatic impact wrench. It doesn't work like a pneumatic wrench, but for 12V it gets the job done. It takes a few cycles to built up momentum for each impact, but it will break the lugs loose after a 4 or 5 hits.It will also tighten the lugs but I would recommend using a torque wrench. I don't know what torque this one is set at.What I like about this one is that I don't have to have a compressor and I don't have to worry about keeping the battery charged.I would recommend it.
