I was really excited to use this. I couldn't wait to tie my girlfriend up and I wanted her to tie me up.

It is really fun but it breaks easily. It didn't hold me in and I don't lift weights or anything like that. It held my girlfriend in pretty well but she didn't try to escape with force. Instead, she just reaches up and unclips the wrist. I have to keep her hands far apart or she just moves them close enough together above her head to undo the Velcro. 

Is is just made of simple straps held together with key rings. I pulled and bent the key ring and just popped it right off. Also, the clips are easy to reach and undo while you're tied up. I suppose that is a good thing but I prefer to be helpless and I want my girlfriend to be helpless. I understand that it is a safety issue, so not for everyone. I plan on using a small strip of duct tape over the clip so she cannot undo them.

It's easy to hide. Just slip the cuffs under your bed and when you want to use it again, just pull them out from under the corners of your mattress. 

It looks good, all just simple black. It is really comfortable. The inside of the cuffs are very soft. They never rub my wrists or hurt in any way.

I prefer to use an eye mask with it to increase sensations.

You can put it at the top and bottom of the bed like an "I" or two on each side of the bed to make more of an "X" and spread your partner out more!

I am pretty satisfied with this product but I wish wish wish it was stronger and harder to escape.
