They seem to work ok but they don’t last any longer than my other ice packs

Maybe i need a deep freezer as some have suggested in other reviews

The purple will not frezze in my rv refer and the blue just dose not last long enough to be of much use

In the grand scheme of things plan old water that gets deep frozen in a 11 f freezer will last longer than these ice replacements

But ice makes things wet dont fit in the cooler around things as well and have their own problems

We did not make it the whole 10 days which was knowingly going to be a stretch however these were great for the first 3 to 5 days in keeping our meat eggs cheese oat milk and creamer cold

Only the deli meat did not get eaten toward the end bc we were skeptical

For the longer trips i think it would be important to have a stop where you can refreeze the packs and transfer goods into a fridge for a few days while you refreeze the packs or it may just be more appropriate to use a 12v fridge in the vehicle instead
