It’s everything I expected and more!
Comfortable, secure and versatile. Definitely one of the better purchases we’ve made.
Soft materials and well made. It feels secure without being uncomfortable which I was worried about at first.
Lightweight, comfortable and does the job perfectly. Exactly what I was hoping for.
Once it’s fitted properly, it feels very stable and well balanced. Definitely exceeded expectations.
Stronger than expected and holds weight well. Feels safe and comfortable which is the main thing.
Adds a different feel compared to standard cuffs. Much more comfortable over longer use and looks nice too.
Really impressed with how effective they are for something so simple. Adds a lot more sensitivity than expected.
The comfort level is better than expected. Doesn’t feel harsh or restrictive in a bad way.
