I am thankful for other reviews so I'm happy to leave one. These are the ones the hospital uses and they were/are amazing. It would help if you stocked up on them. My husband had both knees done at the same time. There was not enough ice to keep up. However, as he put it, these ice packs were "a lifesaver". We were also gifted a Berg ice cube bucket. That was amazing as well. Thank you for a great product.
Daughter had MACI knee surgery and left the hospital with a Breg knee ice pack with 3 quite large gel packs. Since it was so impressive and she needed a second ice pack to alternate with it, I looked online for another one. The one I'm reviewing is the closest I could find, albeit with only 2 medium sized gel packs. It's a decent unit, definitely better than what's commonly available but doesn't supply anywhere near the cooling that the original unit does. Additionally, the design allows a 2~3 inch gap between the two gel packs that is covered by the 3rd pack in the hospital grade unit. I would buy the big 3 pack one if I could find it.
