Wow! These handcuffs are great. I love the solid metal and the smooth operation of the parts. I was hesitant to buy them because of the high price, but they are worth it.
The smooth edges are comfortable for long term wear and the heavy weight makes it impossible to forget that you have them on. A really nice combination if you want someone to think about what they have done, without actually hurting them or leaving marks like conventional cuffs tend to. The finger-activated double lock is really convenient, and the way the key sticks open (its clearly designed that way) makes adjusting them a breeze. The single action to unlock (just spin the key all the way in one direction to undo the double lock and main lock! Not the back and forth like american cuffs...) is also super cool. The uniquely huge key is a little annoying but I guess it fits with the rest of the motif. I just wish they used the same key as conventional cuffs. Its still a simple single-tooth key, just jumbo sized.They also are right on the edge of being too big for women with particularly slim wrists. It would be nice if they came with some sort of fitted spacer to make them fit better.
