Works really well, sturdy, comfortable
I like this ice/heat pack. Tried heating up for 30 seconds but wasn’t quite warm enough so did 45 seconds and that was the sweet spot.  I used it for both my shoulder and lower back and really made both places feel better. I love how versatile it is, you can just strap it on and it stays, doesn’t feel like it’s falling off or anything and it’s comfortable! I would recommend if you are struggling with aches and pains.
