I think that these cuffs are definitely for the newbie BDSMers or those who just want something new and exciting because when it comes down to business, too much of a jerk can let your "prisoner" escape. Definitely do not need to worry if you lose the keys to these cuffs. Beginners would seem to enjoy these much more than any one person or couple who is advanced in bondage and restraints. Make sure to not put these cuffs on too tightly as well because they can cut off circulation.

The metal will definitely last but the fact of the matter is that they are easy to get out of. If you wish to escape from them all you have to do is give a good jolt and they give way. There is absolutely no room for the tender skinned either. Talk about bruises and scrapes these metal cuffs are sure to give you some damage if you do work against them at all. Also these cuffs can only work on wrists unless you have tiny ankles and will hurt even then I am sure.

Product did not work that well for me, really was a let down when I was expecting to have to wait for my partner to come unlock me from my bed. I got out of these little suckers within minutes with a bit of bruising to show after my escape.

However these little cuffs can easily fit into any purse or glove compartment if you are looking for something travel handy to restrain a partner. But don't expect them to stay if your partner gives much of a struggle because they likely will get out.

I also found that the metal is good for adding a chill to sensitive areas. Make sure that if you do get anything on them you clean them afterward because nobody likes rust on their cuffs/wrists.

Well I was quite the little escape artist getting out of these cuffs minutes after my partner had locked me up to the bed. Have to say I got punished for trying. Ended up being a bit bruised from the harsh metal.

Still super easy to escape from and really have excluded them from most of my play time. Good luck to anyone who does use them, these are best for beginners.
