I have two Berg gel ice packs that each are 11” x 5.5” (effective area 10” x 4.5”)7 with a sleeve that holds both of them that I brought home with me after my TKR. I have been using that and a smaller 3-sectioned gel ice pack that I borrowed from my daughter. Since I need to ice my knee and my hip/thigh, I decided last week that I wanted additional ice packs. After extensive research on Amazon, I bought
Rester's Choice Large Ice Pack for Injuries | 11" x 14.5" - Pack of 2 | Hot & Cold Pack | Reusable Gel Pack, Durable Construction, & Flexible When Frozen
that cost $29.95 plus tax. Since I’m a Prime member, there was no shipping.
I received the ice packs on Sunday. There are three sections in each ice pack with an open area across the end. The gel was not evenly distributed among the three sections, so I pushed gel up to the top from the section that contained the most gel and redistributed it with the gel in the other sections so that there is basically the same amount of gel in each section. I left the packs in the freezer for about three hours (directions say to freeze for a minimum of two hours), and they were very frozen when I removed them to use them.
The description said they are flexible when frozen. They are not extremely flexible when frozen, but I did not find that to be a problem. They softened a bit in a short period of time. One needs to wrap each pack in a towel to use it to avoid freezer burn. I have a couple of light weight dish towels (for drying dishes) that I used. The towels are double thickness on one side when wrapped around the packs, and I put the double thickness side against my skin. The packs are VERY cold; much colder than the Berg packs. After leaving a pack on for 20 minutes, it was still very cold. It was still so cold that one could use it in another area without refreezing if one wished to do so.
I used the packs yesterday and today, and I think they are excellent. Since they get colder and stay colder longer, I think they are a good investment, so I wanted to share my experience with them.
