Cryo-MaxCold Pack, 8 Hour Reusable Cold Therapy Ice Pack for Elbows, Knees, Neck + More, Medium, 6" x 12" (1 Count)

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 made the mistake and put this item directly on my bare skin after freezing (even though it says not to) and I developed freezer blisters. When used correctly this item works great.

I ordered the large cryomax icepack however, what i recieved in the cryomax packaging was 2 comfeytemp icepacks. Lifeweartech customer service were quick to correct this and sent me the correct item. These icepack are the best and longest lasting I have ever used!

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.

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!

I now have two of these cold packs for my back and they are wonderful. I pretty much put aside all the others I was using. They stay cold so much longer than all the rest and have an outer covering which is easily washable. I am sure the other sizes were just as well And highly recommend these.

Used ONE TIME and it leaked pink fluid onto and INTO my new $1200 mattress. I bought two of these 6x12's many many years ago (like 7 or 8 years ago) from my local Walmart and those two are still perfect (same CryoMax brand). I wanted two more but my Walmart no longer sells this brand/style.I did buy and try one that Walmart carried for a while (bought my third one last year), but it was some clay mixture inside and that one sucks :p it only lasts maybe half an hour. So I came to Amazon to get a couple more of the "better ones".I got this one 6x12 and a larger 12x12 on June 22. I opened and inspected them, put them in their blue covers and then into the freezer. I used them the next night, June 23rd.I have residual hot flashes (postmenopausal) and pretty sure I have hyperthyroidism (unmedicated), so my body is almost always out of whack at bedtime (overheating right away). I put these CyroMaxes on top of my legs and on my chest, or next to my cheek. When they work they're a godsend. They keep my body temp from spiking and I can fall asleep within an hour.About half an hour into relaxing - I felt dripping by my cheek. At first I thought it was condensation (as my other older ones also do just a little when they come right out of the freezer). I was juuuuust about dozed off when my brain said wait a minute - this things still dripping. At that point it had been in use for about 45 minutes.Get up, turn the light on, see what's going on, and it's leaking all over my bed! Run it to the bathroom sink - dripping all the way - it's just gushing out :p Take the blue over off and nearly all the pink fluid is gone with a huge hole in the corner and one of the blue sections in the middle of the row on that same side also burst/missing most of its fluid.I took one of my old ones out of its blue cover and compared the two then took the 12x12 out of its cover. The plastic they used on my old ones is far better than the new ones. The old ones have a more pliable, softer feeling (yet much sturdier) clear plastic casing. The new ones have a really brittle, crinkly plastic. This is not an improvement! This is a major design flaw. Once frozen the plastic just cracks under the slightest movement. I can only guess the Company went with a cheaper plastic to make the product cheaper to manufacture, which is an obvious mistake. They can't possibly "not know" that this is happening. I came here to read the reviews and see that this is a problem that many other buyers had.I won't return it because I already threw away the box (recycled it at my work the morning of June 23rd, then used the new ice packs for the first time that night) thinking there was not going to be any issue as I'd already had and used this same size and/or brand for years. My mistake :pIt's a real drag that the Company ruined what was once a perfect product - and now it's clearly Not a perfect product. I can't find any other brands out there that are as good as this brand USED to be...which now includes this brand itself...their quality fallen to the masses of cheap unreliable products...
