close to perfect
I use in an auto. repair enviroment to supplement my 18 volt impact driver. Perfect size and weight; love the led headlight. Wish it had a wee bit more power and the hammer housing was finished in something a bit more durable; still I love it. Would buy again and plan to pair it with a extended runtime batt.

12V Impact w/square drive
Works great in tight places without taking alot of room in the tool bag and has lots of power for it's size. I wish it would have came with the combo kit versus the hex type drive which has about 160 inch pounds less power.

WOW-What a little brute!
What a handy tool! Super handy for many auto/motorcycle jobs. Firat job with it was installing shock absorbers. Small but amazingly powerful. Hardest part is learning not to overtorque things. Has a great feel for that.

great tool! superlite weight
works great in an industrial maintenance environment enough torque to break loose reasonable size bolts (don't plan on removing tractor tires but...) variable trigger control works fantastic for installing smaller bolts without stripping. I use it everyday for assembly and disassembly of conveyors and such.
