This device is fine. It's not good, Raine's battle bracelet is much better. It has a few issues with how the watch is attached to the strap. This allows the watch to move about 3 inches on the bracelet and become uncomfortable. The clock doesn't stay straight most of the time either. In addition, there is a Velcro hook on the outside of the belt to hold the belt. I'm sure leaving the belt on was a good idea. But at the same time it tears all the insides of my sleeves on shirts and jackets. There was probably a better way to open this handle. (I originally bought this for my Apple Watch, I figured I'd change the strap so that it's visible and allow the heart rate monitor to see my hand. The way the strap is attached prevents me from doing that) . He holds it in one position and doesn't move. Rein's group costs $5 more but is much better finished. I bought this when I had a moment and couldn't remember the company name Raine for the rest of my life.
