My spouse and I got this product a while back and have really enjoyed putting it to use. The cuffs have Velcro enclosures and are attached to the straps by metal clips. The lining on the cuffs is soft and is great for extended play. They are quite gentle while still being sturdy and I was able to wear them for a good length of time with no visual evidence/bruises after. Add a blindfold and your favorite toy(s) for lots of teasing/punishing fun.
Setup is super easy. The base straps slide easily under the mattress and can be adjusted to the desired length(s) within seconds. When not in use tuck the ends under the mattress and no one will know they are even there! We detach the cuffs and keep them separate so that the Velcro doesn't get fibers in it.
The only negative thing I can think of is that the price is a little high for me. We bought it on sale which was just another reason to smile. Overall I love this purchase and if it ever breaks my spouse and I will definitely be purchasing a replacement. However we've had it for over 2 years and have never had a problem and honestly, we don't expect any with how well made it is.
