Love. Them. My boyfriend got these as a joke but it turns out I have a slightly kinky side. Pretty good quality for the price. I was very pleased with my purchase. Very pleased.
I gave some to my friends as gifts - they're falling apart left and right. I used mine once, definitely no holding power there. You can tear through it like you're the Hulk.
What can I say, they're sex cuffs. They're soft, durable, and my girlfriend always wants to have sex. Can't ask for more than that.
