CryoMAX Cold Pack, Reusable, Latex Free, 8 Hour Cold Therapy, Large, 12" x 12" (1 Count)

These work great! I’ve had multiple sizes of these, and I feel like I’ve had packs that work really well, and others that last 2 hours. I think the longer you freeze it for initially, the better they will work. Try for at least 24hrs. My first one was amazing and would last overnight and still be cold and usable in the morning. I bought another that just did not stay frozen, and my third, the T shaped 12x18 size, definitely was not ready after the recommended 6 hours of freezing, but 24hrs later it was full frozen and super cold. Great for hip pain, lower back pain, and sciatica.

I have had 2 back surgeries in the last 6 months and now I have a new issue at L5-S1. This ice pack has really been an answer to prayer! It stays icey for a very long time, and I am able to take less pain medication because of wearing this ice pack. I’ve only had mine for about a month so I haven’t had any leaks. But honestly, if mine started leaking soon, I’d just rebuy for the cheap price they are. When you’re in constant back pain, natural pain relief is priceless

Absolutely love these ice packs. I’ve had three foot surgeries and these things are a life saver. I have multiples so I can alternate to a new one once the current one is no longer cold. I had one leak and customer service made it right. Not only that I love them so much I just ordered one for my sister as well who broke her toe!

These cold packs really work and will stay cold, for 6 hours or so, for me. If it’s an extremely hot day it may last less time. I tend to overheat so these work great! They also help with someback pain. The strap doesn’t help me just because I don’t use it anyplace that would be strap-able.The reason for taking away one star is that these do have a tendency to leak eventually. Even with that, I have had multiples of these over the years and will continue to look for them and replace when the leak is more than I want to deal with. When I notice the leak I just put the freeze part in a gallon freezer bag and put the whole thing back into the cloth bag. The 2 I have now are from Amazon and have not leaked yet in the last year.

Takes a bit longer than others to freeze but Stays frozen much longer than any other (45ish minutes); this is my 4th one (it works so well that I’ve bought for family members); the pouch and elastic strap keep it in place very well even when you need to walk around

I was very hesitant to believe that these would work for eight hours. It’s summertime and I live in Hawaii. Ice packs seem to only last for 20 or 30 minutes around here. A couple days ago on the hottest day we’ve had in a long time, I brought my 2 ice packs with me as I had injured my back. I originally bought two so that I could wrap them around my arms after Allergy Shots to help with the swelling. Anyways, I started around 9 am , I ran around doing errands with it on my back. Around 1 o’clock, I was going to an event in the park and did not want to bring it. I had brought one additional old-school hard ice pack as well with me (Read the directions to see why). It has been inside a cooler. (and was not super cold anymore) I put the 2CRYOMAX ice packs on top of each other with the hard one in the pile as well. I took my sunshade for the windshield and laid it over the ice packs that were on my seat. The windows were up, and the car was in the sun with no other shades. It was crazy hot that day. I came back around 5 PM and absolutely positively could not believe that the CRYOMAX ice packs were still cold. I honestly was not expecting that, I had already been impressed. I don’t mean, cool, they were cold! Definitely read the directions and make sure they are frozen solid before you use them if possible. The liquid won’t freeze the same way the little balls will. I am beyond impressed with this product and have already shared it with the injection center at my hospital. The only two things that I would want to see changed would be the color of the liquid, if it were to leak, in my opinion, that color would be likely to stain. The other thing I would like to see them change is having the flexible plastic CYROMAX Pac, feel more durable. Don’t get me wrong, my gut tells me that it is extremely durable… It’s more of a psychological thing I think. I will update if there are any problems. Super impressed!!!! There are some reviews that say that it does not say cold. I think the problem is that they are not letting the balls freeze solid first. Additionally, I have noticed that once my arms are numb from cold, it often feels like any ice pack I’m using is no longer cold, but if I take the ice pack and put it against a different part of my body, I realize it still is very cold and that I was just numb to it. Perhaps some users have had that happen. I’m not affiliated and I have not been paid or given anything free or whatever it is companies do to sometimes get reviews. Even if these only work half as good as they did that day from now on, they’re still incredible! I’m just a super happy customer!
