The best! Helped immensely with knee pain.

I use this product regularly after workouts and jiu-jitsu to recover. The ice packs, when fully frozen, are easily manipulated within the slots to provide very good coverage, surrounding the knee joint and stay cool enough for two full 20 minute icing sessions with 20 minutes between the first and second session. I have used the item many times and the quality of material leads me to believe I will have use of the item for years. I highly recommend this product for injury recovery.
