Easier to Use Than Its Big Brother

This drill, used with a 1" SDS-Max bit, can drill thru solid granite at the rate of about 1-1/2 to 2" per minute; awesome performance. It's easier to control than its big brother (which I'd rented on previous occasions) for drilling holes in granite.
I've used this rotary hammer in "hammer-only" mode with an SDS-Max chisel, again into solid granite, and the chisel performed well, too.
Having variable speed would be nice, but doesn't really seem to be necessary; you only have to apply enough pressure on the drill to prevent the bit from hopping up and down in the hole that you're drilling.
