Techni Ice HDR 4 Ply Reusable Ice and Heat Packs for Back and Shoulder Injuries, Keeping Medications Cool, Keeping Food Fresh, and Reducing Power Usage in Refrigerators (12 Sheets)

These are wonderful. We use them mostly for icing my husnands knee after he had knee replacement. The ones I just purchased was a gift to my sister who fell and broke her arm. The best thing about them is that we keep about three or four in the freezer and they take up so little space. They are very strong so no leakage. Have had ours for about eight years.

Have been buying these for years and they are the best ice packs for coolers. They get super cold and stay cold for long periods. Annoying to activate but worth it. I fill the tub and do a bunch at once. Then set them out and dry off before stacking in freezer

These are phenomenal! I have used them for years. Several times it has been 90 degrees all day and they keep everything frozen. We do have a good large ice chest but these ice cubes work so well, I highly recommend them!!

These keep cold items colder longer than most ice packs. I use them weekly at the farmers market for keeping frozen items frozen. They work great for this. Not the best for things like veggies that need to stay cold or canned drinks but can be used in combination with ice. I have used them on day trips where drinks need to stay cold. Works great. I did experience the leaking of slimey matter when they start to defrost. This can be rinsed off and if it really bothers you, put them in a 2 gallon ziplock baggie. Tried the heat option as well and this works good too. I used kitchen towels layered around the packs to keep the slime away from my food.

for me, better than the softer gel packs....gets extremely cold and hard, and stays cold for many hours in a cooler

We have used these for years. Stays frozen for along time. With these we use less ice in our coolers. After awhile they disintegrate and have to be replaced. One thing I don't like is they do get slimy even though it says they won't.

Was a good purchase. Its of good quality and size just as described. The freeze time was great. Good purchase at value for my money.

I've bought several from the Orange County Fair over the years. Great to see them on Amazon and so much less!

I’ve had some of these for 20 years or more , sadly the original sheets were past their best , I was excited to receive these new ones but they are terrible. The resin seeps out of the pours in the plastic when they defrost covering everything in a slime .
