Query: Awesome Fastener

This little tool is the best driver i could ask for. The reviews that say the PS40 dosnt have any torque, must be talking about something else. I just got done helping my brother in law put a roof on their barn and i used this thing on 3 1/2 inch and 2 1/2 inch screws all day (1 battery change). I was putting screws straight into nots in the wood which were very stiff and it just pushed them in. I also used it to fasten sheet metal to the roof and using self tapping screws it was so easy. I picked up my dewalt 18v drill/driver and tried it out for comparison but the bosch impact driver is just so much handier, the dewalt went back in the box. Great ergonomics, good power, and style make this my favorite tool.
