Very good. It's just a shame that the sockets aren't suitable for aluminium rims, as they're too big for the holes.
After two disappointments with air screwdrivers, I bought this very powerful electric screwdriver. This thing is tiptop!
I've had this impact wrench for five years, great product, wheel changing is child's play. Wouldn't give it away again. Remember to retighten the bolts afterwards with a torque wrench. See car operating instructions for tightening torque.
PERFECT :-)
