Concept great, but started losing air.
Needed this for a chronic herniation. It definitely stretches your neck and offers relief. Problem is that after 4 uses, it started to lose air slowly. Still works, but have to keep pumping to stay for a period of time. The velcro strips could've been placed closer together as it is hard to get it closed completely. Probably not good for someone with a very small neck. Got a little relief, for not much money.
