Arctic Ice Tundra Series Long Lasting Reusable Ice Pack - 5° Fahrenheit Cooling Point - Designed to Maintain Freezer-Like Temperatures in Coolers

They are exactly the size I need and are well made (and in the US), but be advised: these have to get COLD to freeze. If you have a smaller fridge with only 1 controller for both the fridge and freezer, it may not get cold enough. A larger unit with independent controls will be fine—set the freezer to 0 and leave them in there over the weekend.These are best for keeping frozen stuff frozen, not cold stuff cold—get the blue Chillin’ Brew series for that. The purple ones are good to get your ice cream home from the store, not to keep your lunch cold.The temperature differential is too great to use these to keep things cold—these work around 5 degrees and cold things are generally above 32—all the work goes into getting the items colder rather than keeping them frozen.Be sure you want a frozen food pack—these are what you want for that. They work well, come in good sizes, are rugged and won’t fail, and are made in the US.

Seriously I'm pretty shocked they live up to their hype. I've played around with various generic ice packs and used dry ice for camping (this still aren't THAT cold though) and I'm just impressed. We used a very thin walled soft cooler to pack stuff for the holiday drive. 7 Hours sitting on the floor in the middle row just above the exhaust. When I opened the cooler the ice pack was still half frozen, with FROST on it, and the cut fruit in a baggie right under it was itself semi-frozon (didn't start that way). So not only did the pack not thaw out in all that time (lots of capacity), but it got managed to actually freeze someone (it absorbed a lot of heat).Again, this isn't dry ice. If you need that much cooling capacity only one thing will do. But if you're looking to keep things cold and DRY for a good while these are amazing. I bought a Small, Medium, and a Large. Now I'm tempted to try an XL to use in the camping cooler along with a smaller block of dry ice.IDEA: Instead of replenishing the dry ice in the cooler, use the spare dry ice to refreeze the ice pack! Hmmmmm Should keep me from accidentally freezing things that shouldn't freeze.

Best ice pack I’ve ever owned. You can forget bags of ice. Sometimes takes a while to freeze solid, but still worth it. Highly suggest

These products did not last as long as I expected. Within the first 1 to 1 1/2 years, the 1.5 lb pack failed to freeze and so was useless. After less than 3 years, the 5 lb pack also failed.

It works. in a cooler, I wish it lasted longer, however, my fridges freezer was having a hard time. I put in two of these when the freezer was at 27 degrees and would not go colder. (They were frozen from being in a different freezer.) 20 hours later the temperature was 5 degrees—I was very happy

Seriously though, it does get cold. I do some outdoor summer sports where I normally bring a cooler with water and ice. I switched to using one of these instead of ice. It did not do as good as ice but was a lot simpler and easier, not to mention cheaper. I purchased a second one, and now it's almost as good as ice, but leaves more room in my cooler, is easier to work your hand around fishing out items from your cooler. No more sharp ice edges. Now I don't have to make a separate convenience store stop for ice, and I don't have a ton of water to dump out of the cooler after it's melted. To sum it up, it's cheaper, simpler, and more convenient than using ice. Also noteworthy, is more room in the cooler, and if you have to transport a larger cooler over a distance, it is a little lighter as well to consider. For me, it was nice not having to make a separate stop for ice too. Water that was placed in just the right area did freeze a bit, but after taking out of the cooler in the summertime heat, was easy to enjoy after mere moments.

It kept my food cold but after 4 hours when I touched the actual ice pack it did not feel as cold as I thought I should or as cold as it was when I took out of the freezer and placed in my insulated lunch bag.Update:After several weeks of use it no longer freezes solid.

As others have experienced, this was great at first. But after just 2-3 uses, it no longer freezes. Our freezer gets down to 0 degrees F (colder than many other freezers, because our freezer has its own, dedicated compressor). This ice unit stopped freezing solid. It stays liquid. I've even tried putting it in the back/middle of the freezer. Even after 4+ days, it's still not frozen. And it doesn't work very well when it's in liquid form (I tried it camping last weekend). And this thing was expensive!
