Good in theory but design isn't there yet.
I love this concept because I always sleep on my arms and wake up with it fully asleep and in pain. But the belt is very hard to set and it seems to be made for a large arm and/or for the upper arm. I sleep with my hand under my head and really need it around my wrist/forearm which is really small. The whole thing is too big/bulky to sleep on and too high because of the belt plus the soft thing on top. I think improving the design to be one belt soft on the outside, hard on the inside, to be smaller, and to be able to more easily adjust the belt would make it a great product.
