I purchased my first several years ago. It has been a game changer when it comes to my shoulders. I loved it but felt that the support was breaking down because I’ve had it so long, so I ordered a new one. I was very disappointed. I don’t know what changed, but the support that I loved in my first one isn’t there. I went back to using my first one and decided that it has more support than the new one. It’s too squishy now. I won’t be ordering another one. Vickie Grindle
