"Kawasaki Impact Wrench Kit — 7 Amp, 1/2in., Model# 840017"  Product Reviews

"The seven amps is what motivated my purchase. The foot pounds could be higher, as it is on some competing models, along with an adjustable torque setting...but for the price and home shop use it is doing the job. If you use an adapter from one half to 3/8...(in case you don't have all your sockets in one half size)...you can use it to losen smaller rusted hardware using your 3/8 or 1/4 sockets."

"I was looking for a corded impact wrench for when I change over from snow tires for my 2 cars (2x a year) This Kawasaki meets this need perfectly. I has all the torque needed and the balance is good. It made an arduous job very easy. If there were any improvements to be made, I would suggest an adjustable torque feature."
