No doubt these work exceptionally well for larger wrist detainees in law enforcement but also for fetish play they are very versatile. Wrists, elbows or ankles benefit from the oversize and the short chain length works nicely as a modified leg iron. The O rings located near each cuff allow for further shortening of the chain bringing the cuffs close together via use of a single link. All in all a good looking very configurable special handcuff.
For the price, I would recommend this product. It appears to work well and function properly.
