These cuffs are great quality. The cuffs are comfortable, soft and strong, and use a buckle to close. I liked this aspect because it meant being strongly restrained without needing to worry about the possibility of losing a key. They’d fit all wrist sizes.
Comfort is huge for me when it comes to bondage play. When you are being restrained or restraining into a somewhat uncomfortable position (in a pleasurable way) you may as well get some comfort where you can. Unwanted chafing, or undesirable pain can just ruin a bondage experience.
Considering the price I did not think these would be as comfortable as they were. Or at least would lack in a certain area that I could comment on. Durability wise, faux leather (vinyl) sometimes can disappoint, however in this case these have proved great and seem to be able to hold a good amount of body weight. Although I've only played with them a few times, they seem like they will last for many hours of usage. Like anything their durability will always be partially dependent on how you use them.
The chain is a good length (not too long and not too short), and can be unhooked from the cuffs entirely. This also means you can use the D rings to attach different chains if you want something longer or stronger. Although if you do decide to change the chains, make sure the new chain is still safe and will not cause the current material on the cuffs to stretch or break.
It’s a good quality product, and I’d recommend these for beginners as well as more advanced bondage players as they offer the opportunity to expand with the D rings.
My only negative was I with they were in pink! I just like pink, but for some meeting a specific aesthetic can make or break the experience.
