Review: Can be used as a heated OR cold pack! - Until I received these gel packs, I never thought about using a gel pack for both cold AND hot applications. Who knew? I certainly didn't until I received my order of two gel packs with clear instructions on using them frozen or heated. Heat them in the microwave from a frozen or room temperature state ( pay attention to your microwave voltage and adjust your power level), or submerge them in hot water. Having two packs and two sleeves is so convenient when you're using them frozen. As soon as one pack no longer provides cold relief, swap it out with gel pack #2 which has been chillin' in the freezer. Seamless relief! And don't forget to slip it into the thin, reusable protective cover before use provided by the vendor. This gel pack sleeve is thin enough to allow the cold to work its magic, but thick enough to protect your skin. So far, I've only used the packs frozen and they did a great job. They felt durable, were flexible enough to mold around my foot, and maintained a chill for a couple hours. When one warmed up, I simply swapped it out with my second pack. I realllly like the sleeve - it was so much easier than using a hand towel that can be too thick and kept coming unwrapped, or using a paper towel that also separated from the pack. I highly recommend this item. Here's to your health!
Review: Very useful and stays sold for a long time - These reusable gel ice packs have been extremely helpful for pain relief. They freeze quickly and stay cold for a good amount of time, and the material stays flexible even when frozen, which makes them much more comfortable to use on different areas like the neck, knee, or wrist. I also like that they can be used for heat therapy, just warm them up and they hold the heat well without getting too hot. The size is convenient, and the quality feels durable. Perfect for headaches, injuries, or everyday soreness. Great value and very practical to have at home.

### ⭐⭐⭐⭐ Worth it
*by L***P on November 23, 2025*

This ice pack works really well for everyday aches and pains. It’s very easy to use just freeze it and pop it into the cover. The ice retention is solid, keeping cold for a good amount of time without melting too quickly. I also like how comfortable it feels on the skin, especially with the soft outer layer. The size is practical and fits well on different areas like the neck, knees, or back. The only reason I didn’t give it five stars is because I wish it stayed cold just a little longer. Overall, still a great and reliable ice pack!
