Works well when used as part of a shipping process

We have used these cold packs multiple times now, and they have worked well for us through several freeze-thaw cycles. We are always careful where we place the freezer packs in the freezer and in containers to avoid poking holes in them. One hole and they are pretty much done. We have learned by experimentation that there is an optimal way to keep any food cold, or frozen, as the case may be. First, be sure the food container is insulated, and insulated well. Second, pre-cool the insulated container as much as possible. For frozen food, we pre-cool with dry ice if we can get some. Ice also works, but dry ice takes the pre-cooling to a much colder level. Third, remove all pre-cooling materials and remove any residual moisture. Fourth, fill the insulated container as much as possible. Fifth, add cold packs in any location where gaps or spaces remain. Since the cold packs are added last, the cold packs should be near the top of the insulated container so that the cooled air sinks from the top to the bottom. The advantage of the freezer packs is that they do not drip onto food as they thaw, assuming the packs have no holes! We have successfully shipped frozen food across the country (next day air) using insulated shipping containers with freezer packs and the food has arrived safely. We do not ship with dry ice because while dry ice is permitted on planes, dry ice requires "special handling," which means big dollars, so we stick to using dry ice for pre-cooling only, and pack as close as possible to the time of shipping. Admittedly, there are other options to using freezer packs. However, these are reusable and their rectangular ship is quite suitable for our shipping containers. Occasionally one develops a leak. We have not had any success in sealing a leaking freezer pack, so we dispose of those that leak. The other problem is getting the freezer packs back. Those we send locally we can usually retrieve. Those that go cross country become gifts to the recipient, which needs factored into the shipping cost. There are a few complaints about shipping costs, but generally most recipients are happy to have their food intact and edible and understand that the packaging does exactly that. Freezer packs meet a very specific need, and these are reusable, with care, and are reasonably priced. When used as part of a shipping process for cold or frozen food, they work great. Enjoy!

Don’t think, JUST BUY THIS!!

Your browser does not support HTML5 video. I flew from east to west coast with 7hrs total flight. Bought these and an insulated carton with foam, hoping for my live lobsters to make it alive to our destination (yes alive!! as requested). Here’s how :) I packed this 3 hrs before my flight. I put one R-Brix on the bottom and covered it with a clean absorbent pad, I used my puppies training pad, then the lobster with moist newspapers all over to prolong their life, worked as fillers too. After they are all in I put two more of R Brix on top and covered. I securely taped both insulated foam and the carton and threw it in the center of my checked baggage with my clothes all over just in case it leak or something. Guess what! My lil fellas made it all alive without Airport problem and these RE-FREEZE R-BRIX was still hard and cold when we opened it!! Check out my video! It was worth the gamble!! Thank you for this amazing product! Highly recommend!

Awesome!

I'm a pilot and use these to pack my lunches for multi-day trips. They work great! They stay freezer cold about 12 hours and cool enough to keep items safely chilled for about 24 hours. I would caution anyone from getting these specifically for TSA use. Although they are advertised as foam, all of mine have a substantial amount of liquid in them after a few uses. They would definitely not clear the TSA liquids ban in the U.S. If you're looking for a great ice alternative to keep your lunches cold, however, these are great!

Works Well! And a Much Easier and More Portable Alternative to Dry Ice For A Few Hours.

I flew from Jersey to FL using 5 of these, in two insulated bags in a checked suitcase, to keep homemade ice cream that I made to surprise someone frozen. When I arrived we had 7 hours of being out and about until our 3pm check-in. About 15 hours had passed when it was time to open it and one of the places we went let me put the bag in their freezer for an hour. I was scared to open the bag when it finally came time to reveal the surprise. It was a win! The ice-cream was still frozen! I do think the double insulated bag inside a suitcase helped for sure. Also because these are foam I didn't have to worry about a ton of water melting but there is naturally a bit on condensation but far less than ice. *IMPORTANT NOTE: Prior to purchasing these I noticed someone complained about how flimsy the bags were and that they tore. They are right! The plastic IS flimsy! So learning from their review I always keep each of them in their own closed ziplock back when I use them so I that the plastic always has a layer protecting it from tearing. WILL extend the life of these by a ton! I have never has to repurchase them. I even refreeze them in the ziplock. They basically live in their ziplock bags and from time to time I'll open them to clean them as needed. Since the ice cream mission I have also used them wonderfully to keep my lunch, such as salads, cool on a summers day and to keep groceries cool when I am not heading straight home. Definitely happy I bought these.

BEST cold packs for air travel

I use these when I travel for work to keep pumped breastmilk cold and unspoiled for the kiddo when I get home. They keep cold well, but I wouldn't say they kept SUPER cold. If I had frozen my breast milk, I think that it would start to thaw if I was relying on these alone. I think for straight cold-pack function, there are better options out there... UNLESS YOU'RE TRAVELLING! Then these are a holy grail of cold packs. Since they're solid, even if they warm a bit they still sail through TSA. Gel cold packs can be confiscated if they are not frozen solid. These stay solid regardless of temperature and are easy to pack and travel with. The guard at security actually told me to tell all my nursing friends about these. I have none, so I tell the amazon world instead!
