5.0 out of 5 starsBest, least expensive, instant cold pack BY FAR!
Reviewed in the United States on August 31, 2018
As a former varsity volleyball player and currently an avid outdoors person, I have been using cold packs when necessary for years. No instant cold pack can compare to ice cubes in an ice bag in terms of the amount of coldness or length of time the coldness lasts; however, there are times when you can't immediately get ice cubes and/or carry your ice bag (or your ice bag leaks during a 3-hr flight -- that was fun, especially for the next traveler assigned to my seat). That's when it's more than handy to have an instant cold pack -- it can literally reduce the pain of an injury, animal bite or insect sting, just to mention a few uses. I have tried just about every instant cold pack available -- big box stores, pharmacies, online, you name it -- and with one exception up until now, they are pretty much worthless. There are ones impossible to activate, ones which harden like a rock if you store them in your closet for less than a month, ones which are barely cool when activated, ones which are the size of postage stamps, ones that don't even stay reasonably cold for 10 minutes. Up until I discovered the Dynarex Instant Cold Pack, the only one I could depend on was the Ace Instant Cold Pack at $7.67 for a twin-pack on Amazon (much more at my neighborhood pharmacy). That comes to $3.83 apiece.
I bought the Dynarex 5"x 9" instant cold packs in a box of 24 (yes, twenty-four) for less than $20 delivered. That comes to $0.83 each. I checked each pack in the box and all are just fine. I have used them and they easily activate, they are generously sized (larger than the Ace) and the cold lasted at least 1/2 hour. I can highly recommend them.
No, I wasn't given any external incentive to give this great review; my internal incentives were 1) to help other people find a portable, easy-to-use, handy and really decent quality instant cold pack and 2) to give a shout-out to a great instant cold pack manufacturer who deserves it.
