I bought this drill about a year ago in anticipation of a yearly construction project I do for a student group. During this project, my drill got banged up, had paint poured on it, and was abused  and dropped from scaffolding, without ever quitting. Its major job was the (seemingly endless) drilling of 1" holes using old, blunt, overused spade bits. Despite the poor condition of the bits attached, my drill never slowed down, and the handle let me power through studs. Where others were getting wrist pain with their cordless drills, and having to change batteries, or re-tighten their keyless chucks, i just kept going. The chuck is  SOLID, and lets you really clamp down on bits, and the metal housing for the drill's gearbox makes this thing practically indestructible. I even used this thing to drive several 3" deck screws and it wasn't that hard to maneuver, (though I don't think i'd want to be working overhead with this drill unless i was really in a pinch)
