ThermiPaq Reusable Hot Cold Pack Ice Pack for Injuries - Shoulder, Elbow, Ankles, Back and Knee Ice Pack, Medium, 12 inches x 6 inches

I just purchased my 3rd one and I hope they never discontinue this product. Why do I love this so much? I have used electrical heating pads and other types of heating pads and this one just holds heat much better and for longer. The elastic portion of the outside pouch is very stretchy and durable, even after 50+ uses you will still be using this.The only reason I have had to purchase additional ones is because others in my home did not follow the instructions and heated this in the microwave for too long. This causes issues to the clay material that is used inside the designated pouch which means you will need to replace it. (we recently purchased a new microwave with higher wattage and another adult in my household heated this up for the same amount of time as our older 250W lower microwave). So as long as you follow the instructions you will have zero issues.My advice? Buy one and don't overheat it in your microwave. Thank me later.

I am happy with my purchase of this item. It’s small but good size and retain heat well.

Colder than gel pack, yet molds nicely to body parts, just as you would expect clay to do. Lasts much longer than gel or bag of crushed ice. Velcro strap on the cloth cover holds it in place for knees, shoulders, etc. Just bought second one, so I can “wear one, freeze one” for recent shoulder injury

Like the convenience of microwave and flexibility of the wrap

I love this product - use it for a cold pack. I keep it in a ziploc bag in my freezer and it's always ready to use. It's the perfect size for using on neck, shoulder, or knee.

This works wonders for my lower back. If you have trouble falling asleep just place this heat pack behind your neck. Instant relaxation and sleep.

We already own this product. Ours was old and deteriorated.

I used to be a very active athlete, and found this years ago to be the best option for a hot pack for home therapy. It's easy: just pop into the microwave for less than a minute, wrap around the affected area, and go read or watch tv or make a nice lap for the kitty. No need to put in boiling water or anything like that. Lasts for years.Lately I'm less of an active athlete and more of a creaky person with back pain, and this comes in very handy for when I need a hot pad rather than an ice pack.I highly recommend giving this one a try if you're looking for good hot pack.
