Well Ed, mine has lousy power, and about a month after the warranty expired, one battery pack went dead.
My 12V National (Panasonic) drill will drive way more screws and way bigger screws than the 14.4v Bosch, also, the Bosch is "loose" between the chuck and the clutch ring of the drill, if you have a bit in the drill, you can wiggle the whole thing about a 1/4" back and forth. Again, I took it to the place I bought it, and they had a Bosch rep there, he said that as it was out of warranty, they would have to charge to fix it, and that would cost about the same as a new drill........
We shall see how the hammer drill holds up.
