Lately anything I purchase in impact grade is Gray Pneumatic. My son in law sells the brand so I get his cost but they seem to be good tools. I've not busted anything yet but did lose a machine screw holding a 3/8" head together and they gave me a complete rebuild kit for the ratchet. In reciprocity I purchased another 1/4", 3/8", and 1/2" drive ratchets as I like the feel of them.
I've snapped off literally dozen of the torx head drivers over the years when swapping, or removing pickup beds on Ford vehicles. Didn't snap a single one of the Gray Pneumatic brand in the same application but that could be luck of the draw. Lisle brand are commonly available in the automotive service arena, but not that dependable in my experience. Lifetime warranty but the inconvenience of these snapping off at inopportune times was a detriment.
