Review on AOBEN 21V Brushless Cordless Impact Wrench With 1/2" Square Driver, Max 300 Ft-Lbs Torque (400N.M), 2X 4.0Ah Li-Ion Batteries, 6Pcs Impact Sockets Set, Fast Charger And Tool Bag by Govindarajan Diepenbrock

I gave up on my air impact wrenches to do difficult suspension job of strut/coil replacement with 5 year old rusty bolts in Minnesota.I was going to get a corded electric impact wrench because of good review on how powerful they are.I found this unit and noted the specs on torque, impacts and speed were almost equivalent to the corded impact wrench so I chose this cordless unit.I am delighted with the device; lightweight and powerful with a long duration 4ah battery.

Although, most automotive projects don't really need long duration between charges.I got a carrying case and impact deep well sockets for common items such as lug nuts.I'm pleased with the quality and performance and it has a two year warranty.It would have been nice to have a hard body carrying case and a docking battery charger but the wall charger and cloth bag will do.I would buy again.Tom J.
