These are very nice; they work well and stay warm for quite a while. They are soft, easy to use, and comfortable. The Therapy Clinic I went to uses this brand so I decided to get some for myself to use at home since they were so nice. 😊 They heat up quickly in the microwave. Doesn't take very long to heat them, so be careful not to overheat. I put two knee wraps (which I use for my shoulders and back and they work quite well for that) into the microwave at the same time and they fit well because we have a large one so I don't have to fold them in half or anything. You can fold them though if you need to. The first side I do for 90 seconds and the next side 80-85 seconds. We have an old 700 watt microwave so it will vary for newer ones.

As others have said, if you attach the velcro to the fabric itself to keep them in place it will make the fabric pill and it won't look as pretty and might eventually tear it (my feeling), so I try not to do that. I did it once and I decided not to any more if I can help it. I also attached the two velcro straps to each other so they don't stick to the fabric by accident which happens quite easily. The straps can be handy to have since you can wrap them around yourself if you're sitting in a chair and it will stay in place better. That's why I haven't cut them off.

Good product.

After knee replacement this wrap provides the right amount of cooling all the way around my leg. Make sure you don't stick the velcro straps on the blue material as it tends to fray it. It is very cold for about 20 minutes starting at 0 degrees

This wrap is great! It's light weight, reasonably sized, and holds temperature for a long time. It comes with a convenient bag for storage to prevent your wrap from becoming wet. The Velcro straps allow you to fit your wrap as loose or tight as you prefer. I am very pleased with this purchase and I'm sure it will last a long time!

I ordered specifically to help after knee replacement surgery; my physical therapist recommended this brand. I also got another wrap, same brand, without the knee "hole". Both did an excellent job keeping the swelling in check while I recovered, through lots of physical therapy. I also use to help with lower back pain. I have not used them as "hot" packs yet, just as cold. I keep them in the freezer.

So disappointed in this item. I have other Elasto-Gel products that work great but this one was an epic failure. It is large and should work well for any size knee, smaller knees may have to double it around the leg, but that would be great at keeping it cold longer. It's a large flat gel pad with velcro straps shaped to fit the knee area. I think because of its large flat surface it allows the coldness of it to reach room temperature in about 15 minutes. Coming straight from the freezer I felt like it should stay much colder for longer than it did. Maybe it was a defective one because my other Elasto products do stay really cold for up to 45 minutes and then they still have a coolness to them. I tried to exchange it but the seller wasn't interested in that so I just returned it. I have the foot gel pack and I'm just using that around my knee and it works great.
