Dynarex Disposable Ice Packs for Injuries - Instant Cold Packs for First Aid, Swelling, Sprains & Abrasions - Single Use Cold Pack & Cold Compress Packs for Joint & Muscle Pain - 24-Pack, 4X5-Inch

Why did you pick this product vs others?: Used these for a while and they work great and last a long time. Easy to use and carry with you for when they are needed.

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.

I Am with you mate i bought 2 boxes of this "ammonium nitrate" but when mix with aluminum powder and shot with a 7mm or ak 47 does not explodes. there is two options this might not be PURE 100% Amonium nitrate OR! My aluminum powder does not work or is not dry so to prove that i just order brand new aluminum powder to give it another try if it does not work i am pretty sure the manufacturer added a sustance to prevent the product to be explosive, the reason it makes me think that is because i have bought in the past this same product and it has work REALLY GOOD! but all of the sudden does not work now. i have experience using this product as a cold pack because i got burned with my ak 47 accidently touch the hot barrel so i apply one of this cold packs and it works AWESOME! really cold and it does the job really nice that is why i am rating it 5 stars but for as long as explosive targets goes this didnt work for me hopefully it was my aluminum powder will see as soon i get my new aluminum powder i will be rating it again in the mean while i already order another brand to see the diference if you are intending on using this product as a target thanks for reading. if you want this product fot is original purpose IT WORKS GREAT

It's fabulous for a different reason than I bought it for. Good: 1.easy to use and store 2. Affordable...Most health products break the bank for chronically ill people 3. Very cold Bad: 1. Short lived...maybe 2 hours of cold if your lucky 2. Cannot be used as an ice pack replacement (for swelling or headaches or injuries) basically it's pointless and useless for its intended uses 3. Misleading...uses and time it lasts I bought these for headaches and swelling for which it is useless. However, I have an illness that causes my body to be in a constant "fight or flight" mode which causes extreme Temperature problems. I n need really hot or really cold, if it's in between likely 78 degrees my body rapidly come cycles from sweating to freezing and back. Relief comes From extreme scorching showers or ice cold showers or ice packs etc.... anything to tell my body what temperature it is to stop the cycling. These are fabulous for that purpose!!!! Wayyyyy easier than showers and wayyyyy easier/cheaper than making big ice packs. So I love them. But I sure wish they were cold enough,cold for 5-6 hours/ more gel like rather than liquid so I could use it for headaches and swelling.

I’m recovering from a pretty sick injury, and while I’m walking fine, I sometimes fine myself in immense pain. The only problem with this is that I work in sales. While I’ve minimized the amount I have to go out to the office on calls, I still have to go and visit my clients, and while I drive everywhere, it’s still a bit of added movement on my knee where I can’t necessarily always afford it. While with a client, who luckily is also a friend, my knee was feeling so terrible that I had to sit there for an additional hour because I was in so much pain. Luckily, my buddy’s intern ran out and got me one of these ice packs and wow. It worked like a charm. You just smash the pack and it gives you instant relief to your pain. I bought these online (wow, so freaking cheap compared to in store) and started keeping them in my trunk. It’s made a huge difference in my daily work life and I even use them at home. While at home, I do some of the exercises my physical therapist requested I do at home, then ice my knee, and then top it off with a bit of this ThermaChill Pain Relief Roll On Cold Therapy, 3 fl oz. - Top Choice for Arthritis, Migraine Relief, Joint & Muscle Pain - Limited Time Offer: Buy 1 Get 1 Free! stuff that an ex bought for me. It works great because it cools and warms the pain until I’m able to fall asleep. At any rate, definitely buy these packs even if you don’t have an injury, they’re so convenient and easy to use.

Best .
