I've used this impact screwdriver for a year and a half daily. So it's tough enough. It drives big screws like butter. Amazing! It drives Phillips as nicely as Robertson without stripping, also amazing. It is very short, so it easily fits between joists. The NiMh batteries are better than NiCd: they carry more power for their weight, are less finicky about charging technique, stay charged longer when unused, and charge rapidly.
cons: Bits always get stuck in the hex chuck, requiring Visegrips to get them out. But I generally use a guide sleeve. Phillips bits sometimes shatter. Robertson bits sometimes jump out of the screwhead since virtually no force is needed to drive the screw. It is single-speed, so you have to be careful as the head sinks into the wood or sheetrock. Also, it's very very loud, requiring hearing protection.
My other impact screwdriver is a Makita. That version has external ports for the motor brushes, and a built-in worklight. But it's hex chuck jams just the same.
