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

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 ordered these to take on vacation to treat my tendonitis and stress fracture. My doctor wanted me to ice my foot several times a day and I was worried about having access to ice. I had seen these at Walgreens, but they were expensive. They were much cheaper on amazon! I was worried about shipping them, but they all arrived in perfect shape. I packed a bunch of them in my suitcase and they survived a ten hour flight in my checked luggage and a taxi ride to the hotel with no issues. It was a little difficult to pop the packet inside to activat pe them, but that was a good thing since I could toss one in my purse and carry it around all day with no problems. They are the perfect size to treat my foot issues and they easily slipped inside my walking boot so I didn't have to worry about taking the boot off. They are totally liquid so they molded to my foot easily and they got cold enough to provide relief. Obviously, they weren't as cold as a frozen gel pack or a nice cube, but they did the job and helped my foot feel better during our walking intensive vacation. I will order these again and always keep them on hand!

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

I found myself in a situation where a cold pack would have been beneficial to an injured family member. No nearby businesses had cold packs or anything to use to keep a wound cool while we traveled to a medical facility. (Injury did not require ambulance or first responder service.) Once we arrived at the hospital, some of these instant cold packs were provided and were a welcome relief to the pain and swelling. The cooling effect lasted about 20 minutes per pack.I decided to make some first aid kits to augment the ones I already carry in my vehicles and include some of these Dynarex Instant Cold Packs in case I find myself again in a situation where a cold pack would be helpful, but may not be easily acquired away from home.The concept is awesome, however, due to the ease of activation, five of the packs had already activated before I opened the shipping box. If there is a way for the shipper to package them to prevent activation, that would help. I have left feedback for Amazon regarding this, but wanted to mention it here in case anyone really needs all 24 packs to be ready upon receipt they will be aware of this issue.It may be that the smaller size would not have the same issue in transit as these larger ones, but I only ordered this one size so I do not know for sure.

I use quite a few disposable cold packs in my volunteer work and had been getting a nationwide drug store chains private labeled product.I thought that I would give these a try after doing a fair amount of research on these types of products.I have only been using these for a few weeks now but I am very impressed with their performance so far.The price is right and I love the free shipping from BP Medical off of Amazon.They activate easily and seem to stay cold for a good 15 to 20 minutes, which is about the time that you would want someone to ice an area of their body in one session anyway.It would be nice if they would come with a protective sleeve as the drugstore brand has started to do to provide protection from direct skin contact, which is very convenient, but that is a minor point.I would highly recommend this product.

I'm not entirely satisfied with these cold packs so I'm giving 3 stars. Pros: They're conveniently sized and not too expensive; they get cold instantly. Cons: They get cold, but not super cold - so, more like the temp of a bottle of water coming out of your fridge as opposed to the temp of an actual ice pack from the freezer; besides not being very cold, they don't stay even that cold for long - 15 mins passes and it's like having a cool water balloon on you; they're super poofy and sloshy - meaning there seems to be a lot of air inside, so the liquid moves around a lot - it's not like an ice pack that will just sit in place because it will form to your neck, shoulder, knee, whatever - it's like trying to get a balloon, filled with 1/2 water and 1/2 air to sit still. Also, and this should be apparent, but I'll point it out anyway - condensation forms on the outside as soon as it cools down and they're just plastic so they're slippery and wet - if you don't like that, you'll need a towel or something to wrap them in - but then, the fact that they don't get very cold comes into play and in 5 mins or so, you won't feel any cold through a towel.So if you just need something for a quick cool down - maybe to sooth a headache for 10 or 15 mins - they're fine, but that's about it.

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.

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.

Best .
