I use wrist straps for my dSLR cameras. I have never had reason to buy anything more expensive than this item (and its predecessors).
I have used this strap on these Canon camera bodies: 5D Mark II, Digital Rebel T3, Digital Rebel, and Rebel 2000. It works great on all of them. The padding in the pleather grip is full and soft, and the texture on the pleather itself ensures the grip will not slide off my hand.
