I've been pretty critical of all the new Porter Cable. From looking at then and handling them, I was convinced that they were all junk. I was at the Pro-Tools outlet store before Thanksgiving to get a Bosch 12 volt Li-Ion driver and the manager stopped to talk to me. His advice was to get the Porter Cable model. It came with 2 batteries, charger, and a canvas case that would hold everything where the Bosch was one battery, the charger, and the card board box packaging. I expressed my opinion about the new Porter Cable stuff and he made me a deal. Buy this thing, hang on to the receipt, and I'll give you a total refund anytime on the next six months if you don't like it. Well, I fired it up last week and wow, this thing works great. I drove several dozen lag screws into wall studs, and drove and removed cabinet hardware screws over and over and this thing never slowed down or balked once. It's still going strong on the original charge on the first battery.
