We’ve had two of the 10” x 13” size on hand since a hip surgery. Nine months later, the gel is hard. Junk? They worked great when they worked.
It's important to note they only give a year warranty. While I loved this coldpac, it really does change texture, formation, and effectiveness over time. I guess I assumed these things wouldn't really go bad and left one in the freezer all the time when not using. As the years passed, it got a weird texture where it's broken up into chunks and bulky. Just a warning for long term expectations.
It’s amazing. The large size is great to drape over both knees, a hip, place on low back, etc. I love if
