These work surprisingly well.

Yes, they look like a gimmick.
Obvious points: These go on and come off faster than tape gloves. They protect better than tape, last longer, and stick better. They make jamming in cold or hot rock much more tolerable. Purists will call you an aid climber, and they'll have a point- these do make jamming (at least, the cracks you'll fit with them on) easier.
