These really work. They get very cold and stay cold forever. I used them to chill pumped breast milk on a business trip and they kept my soft-sided cooler bag as cold as a refrigerator for an entire day in transit.

I love these things. They're not filled with any kind of liquid to worry about leaking and they keep cold all day long. They last for years, but over time the foam does seem to slowly go away. But even when half the foam they still work great.

awesome ... very reliable ... I eat several meals a day and carry a huge meal fitness bag >>> keeps drinks colder than actual refrigerator and meals cold ... so far I've tried as long as 16 hrs and could not tell difference in temp comparing to just out of freezer ... just softer ... not sure how long would last left out in open though. It's great for everyday use, emergency or cold therapy for injuries or pain.

These worked great for camping. After 3 days in our small cooler they were still cold.

These are great for the usual cooler, lunch bags....they stay cold for at least 9 hours (when packed together even a couple of extra hours)
As odd as this may sound, as a migraine sufferer I've placed about three of these in a fleece pillowcase and "encased my head in ice." Amazing.
I bought extras because everyone in the family is now using them (and bless their forgetful hearts!) they occasionally get tossed with the remnants of the lunch (teenage boys?)
We have a dedicated shelve in the freezer for these. Amazing product.

In the description it says keeps food cold for 14 days. I think they meant 14 hours. Kept everything cold, not frozen things frozen.
