These cuffs are superb: a good design, made of high quality materials and well constructed. I'm not aware of anywhere else that sells this quality at this price. They're so comfortable that they can be worn overnight with ease, even when they're tightened up enough to prevent escape. And on that point, it's worth investing in a set of padlocks for the lockable buckles, so no one can decide to unbuckle them before that's allowed As you might expect given the thickness of both the leather and the padding they can be a little tricky to buckle up tightly at first, but after a few hours of wear this is less of a problem. All in all a great product which is further enhanced by the availability of other matching products such as collars, thigh cuffs, bicep cuffs, etc.
