Medvice 2 Reusable Hot and Cold Ice Packs for Injuries, Joint Pain, Muscle Soreness and Body Inflammation - Reusable Gel Wraps - Adjustable & Flexible for Knees, Back, Shoulders, Arms and Legs

Like both packets, they are well made so I believe they will last. Have not tried heating them yet, but works great cold. They stay cold for at least an hour.

Just received and first time using but so far Im extremely satisfied with this product. Works great!

Between icing knees, necks, shoulders, and feet, this ice pack is awesome, and I love it!!

Gets really cold & stays cold for a REALLY long time!

perfect for lower back. keeps ice pack in place

I would give it more than 5 if I could. I had to have me surgery due to a skiing accident and this has been an unbelievable relief! Havent heated it up, but it freezes pretty fast and is flexible so it can get just right. The holder is great too. Great product!

Good price. My skin had been irritated by used hospital bed the air mattress would overheat electrical surges would happen. I used these until I was able to get a better mattress. The packs had me cool and comfortable.

Heavy duty ice packs. Good quality product.

I love that I dont have to sit around while I ice my lower back. Works great!

This product arrived new and unopened. The quality of the ice packs is decent and the sleeve for the packs is easy to use and comfortable when velcroed into position. My only concern is how the velcro picked the material where it holds the pack into position after one use and I wonder how long it will be functional. This is the reason for my 4-star rating instead of 5. Aside from that Im very pleased with this product...both the hot and cold packs. Note: be sure to read instructions for microving the hot pack, as the instructions specify a time limit to keep the bag from rupturing.
