This is the real thing! You don't want to buy anything else if you have shoulder, neck or back pain! I tried all the smaller ice packs and they all bursted after 6 months...This is exactly what my chiro uses and it stays on your shoulder, cold for a good 15 min. or more (but it is recommended to use ice only 15 min. every 2 hours). The thing withice packs and shoulder pain, is the icepack always fall or flatten right where you need the ice: not this one! I might have to make some room in the freezer...but eh, it's really worth the relief. If it burst, I think I'm going to cry. Let's see. If it bursts...I will update my review instead. The vinyl is very thick, though. Stop spending money on little blue icepacks: I recommend this one. That's what I really needed.
