ICEWRAPSHot & Cold Ice Packs - 3 x 5 in. Soft Gel Ice Packs – Reusable for Injuries Headaches, Joints, Fevers, & More – Made of Pro-Grade, Puncture-Proof Material (6 Packs)

These work well, just as expected, can easily apply hot or cold. They heat up very quickly so you have to be careful. I haven't timed it, but it seems around 20 minutes is enough time in the freezer to get some good cold application out of them, so with 6 per pack it is fairly easy to rotate them as needed to apply cold. I did manage to rupture one, but it was probably my fault for not paying careful enough attention. Given the price, can't complain. I have a wrist wrap that is designed to use a larger one of these that also ruptured (very early on). It has a little pouch for the hot/cold pad. So I started using these pads (both hot and cold) in it instead and it works well, these pads are smaller than the one that came with the wrist wrap, but I can slide them into the correct position and they will hold there. Of course, they are also great for icing a small area, e.g. a finger burn. They are small enough that you can also wrap them under a cloth bandage to hold them in place somewhere.

Just like a lot of other people who purchased these, I purchased them for my Samsung Gear VR. I own a Galaxy S6, and it gets to very hot temperatures and thermal throttles; something you don't want while in VR. Because these are very small packs, they fit between your phone and the Gear VR's front plate, although I find it challenging to fully mount the front plate in some cases. If you squish the pack, it'll snap into place fully, but if you don't it'll mostly snap into place (some mounting points won't make full contact, but that's okay because it shouldn't fall off.)Because I live in a highly humid area, condensation is a problem. To remedy this, I rip off a piece of paper towel and place that between the pack and the back of my phone. Condensation still occurs on the front plate, and if you don't wipe it off every once in a while it'll start to drip. Because there aren't any electrical components on the front plate, I don't find myself wiping it off often because it's just water.As for play time, I get at least an hour out of these before the pack gets warm. Even then, heat will transfer to the pack and away from the phone further preventing thermal issues. I've only really tested this for an hour currently, but you can probably squeeze an additional half hour. Although, these come in a six pack, so if you stick them all in the freezer you can just replace the warm pack with a freshly frozen one. If you want to limit the condensation, you can also stick them in the fridge, but you probably won't get the same results as if you freeze them.I'm happy with this purchase, and I'm thankful I looked to the internet for other people experiencing thermal issues with their Gear VR. I don't expect to have any more thermal issues in the future thanks to these ice packs.

I use two of these in each Arctic Air personal space cooler. They are easier to use than water plus ice cubes and do a good job. Of course, they are reuseable.

Purchased these as additional ice packs to go with the LotFancy Gel Ice Pack with Wrap. Though not quite as large as the LotFancy's included ice pack, they fit inside easily. We'd just use two on each side. These are soft gel pack ice packs, so even when "frozen" they are flexible, so you can lay your head down on them and still be comfortable - just what you need on aching jaws after wisdom teeth surgery. We liked having these on hand as we were able to keep several frozen at a time and have plenty to switch out with the warm ones. They seemed to chill pretty quickly and lasted through all of our "20 minutes on, 20 minutes off" rotations for those crucial first 24 hours after surgery. We're still keeping a few of these in the freezer for minor injuries. The small size makes them perfect for holding on fingers or to the face as you can hold one to your head without it being so bulky that it covers half your features.

Perfect size for children injuries.

Wife says they are perfect . Nuf said .

These are flexible, small and time in the freezer makes them very cold. They have to be tied on and lose their coolness in about 15-20 minutes. Might be good for sprains or other small injuries but not really effective for freezing the itch out of mosquito bite.

great value, very handy
