Cryopak ICEPAK Lunch Box, Transparent, 5x3x1 Inches

It's cold, it's a nice size for lunches, or squeezing into coolers that don't have much room left. Didn't buy it for extended use, so probably won't be able to speak to that, but works well in lunches when needed. No problems with leakage (not that I'm expecting any or have experienced it in the past.)

Muy chiquito no me funciono

See how small they are. Too small for much of anything. Deliberately mislead you with measurements in description. Rip off.

Thought I was getting a 7 inch by 12 inch product to replace one I’d lost. Instead got a tiny 3 inch model.

These are crap. I bought 4 of them and in less than 6 weeks they started to crack and split. I sent an email explaining the situation. No response from them. The plastic does not hold up to the freeze thaw cycles of using them in my lunch box.

As another reviewer stated, these are crap, I've had 3 of them rupture after only maybe two cycles of thawing and freezing. I thought maybe they were an improvement over the ones in the bags (that don't hold up either---by the same company), but no, don't waste your money.

Very compact and fit to the most utilities. I love it.
