McKesson Instant Cold Packs 6" x 9" [24 Pack] – Instant Ice Packs for Injuries Disposable, Pain Relief, Swelling, Sprains – Travel Cold Compress for Sports, First Aid, Toothache

Amazing how cold these get. Mine tend to last about 60 minutes with the coolness slowly reducing over that time period. This is also under room temperature conditions and with the occasional removing of the pack from skin. I agree with other reviews that each pack is hard to break, even when carefully following instructions. One time a unit popped a small whole at the bottom of the outer pack as I bent it to break the inner pack. Fortunately it was just the one end and I was still able to use it by positioning it where no fluid would leak out. Nevertheless, be mindful of breaking the pack. I assume making the pack easier to break/activate might increase the risk that purchasers would receive packs that had already activated during the tussle of shipping.

These are perfect and work great in my first aide kit

bought these for a nursery setting. Handy and easy to use, necessary to have on hand, basic cold packs for minor injuries

These are fine. They work immediately upon breaking/mixing and last about 20-30 minutes. They are not very cold but do their job. I bought them to put in my response kit for when I have attacks/flare-ups related to some disorders/disabilities that I live with for times when I’m out of my house and have an issue, so they are not something I use regularly. I could see that they would work well for kids who fell down or as a temporary thing but I think if you are looking for cold enough to really bring swelling down you might need a bit more. Good for a small boo-boo or ok for those of us with Mast Cell Attacks, Migraines, etc. for a temporary solution.

We buy these for the football team every year. Its nice that they get cold once you break them so easy to throw in equipment bag.

I purchased these ice packs for a trip to Rome in the event I develop one of my excruciating back spasms. As European establishments rarely have ice, I figured these would be a great option. I tried one to see how it worked and to my great disappointment, it only delivered a mere 5 minutes of cold before they begin to cool down rapidly. I figured they would at least last 10 minutes, but no. While the description said the pack was 4x6, the cold area is just 5x3, so smaller than thought. I contacted McKesson and they won’t help because it was purchased from a third party. I called Amazon, but they were unable to get any resolution with the seller either. Amazon is willing to go further with helping me, but it would take a lot of time, so I decided it wasn’t worth the effort. Amazon did say, however, that they have had numerous complaints about this product and might do something to note that in the description. Kudos to Amazon for going to bat for me. Don’t buy if you need more than 5 minutes for acute pain.

Decent price for cold packs.

It’s an ice pack so I don’t expect much, but they really don’t stay cold very long. I use them for sports injuries during a game and you’re lucky to get them really cold for any length of time and then they’re just luke warm. I don’t know if there’s a better option out there, but I’ll be trying something new when it’s time to refill.
