I bought these a couple years ago. They’re well worth the money, IMO. I had rotator cuff surgery 6 weeks ago, and these have been a godsend. The adhesive keeps them in place so I can move around, and the long one is perfect to cover my shoulder and upper arm (I also tore a biceps tendon, so it was severed as part of the surgery). I keep them in the fridge; they’re too cold frozen.
