Review: Best, least expensive, instant cold pack BY FAR! - 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 desertcart (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.
Review: Great for traveling - 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 desertcart! 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!

## Questions & Answers

**Q: If used inside an insulated foam container, how long will these continue to operate near peak value?**
A: For long lasting ice, save your 16oz water bottles. Fill them almost full with water and leave the cap just a little loose and put them in the freezer. When frozen securely tighten caps. Use the frozen bottles in place of ice cubes to keep an ice chest cool and they will last DAYS, and you can finish them off as ice water. I've done this for years and it' amazing how long they remain frozen.

**Q: does the product contain ammonia nitrate?**
A: No they do not. the contain calcium ammonia nitrate. No good for tannerite. It must be a new policy

**Q: is this toxic waste or hazardous materials?**
A: Here is the Material Safety Data Sheet for this product, provided by the manufacturer: http://dynarex.com/resources/MSDS/MSDS_Instant_Hot_And_Cold_Packs_(4511-12,_4515).pdfAccording to this: 'This material, if discarded as produced, may be a RCRA "characteristic" hazardous waste due to the characteristic(s) of ignitability (D001). If the material is spilled to soil or water, characteristic testing of the contaminated materials is recommended. To assure proper disposal, consult with state and local regulations and disposal authorities.'I called my local county Haz Waste office and the officer couldn't tell me whether Ammonium Nitrate was considered haz waste where I live, but requested I bring it in to Haz Waste for disposal. Although ammonium nitrate is a fertilizer, many agricultural chemicals are considered hazardous waste.

**Q: are they allowed on planes**
A: Get an old fashioned hot water bottle, put it empty in your carry on and when on the plane ask the attendant to fill with ice. Put a little water inside, put it inside a plastic bag and it will last for about 30 minutes. Repeat! No waste, no cost!

### ⭐⭐⭐⭐⭐ Great product not good for targets
*by R***E on May 24, 2013*

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
