Grizzly IceAmp

Work very well

These really are a game-changer

I like that these are the size of standard soda cans and can be scattered around the cooler. I use these several times a month as I drive 2 hours round trip for groceries, so I depend on these to keep my food cold (or even frozen) for a few hours. I do use larger ice packs on the bottom of my cooler, but these can tuck into small places to help keep the items at the top of the cooler a lot colder. They're also great for small lunch-pail size coolers. One would be perfect and doesn't take up a ton of space.

These work great in my grizzly soft sided cooler. I work 12 hour days and these are still cold when i get home and unpack.

I use these in my work cooler most days, Without them by about 2 the ice is gone and i'm left with water. with these by 7 i still have nice chunks of Ice. If i needed to these would probably work for multiple days in my small 12qt cooler.
