Review: Really great to keep things cool - We actually use these for our catio when it's a warm day. The cats love them and just sit next them to stay cool. They take up a lot space in the freezer but we live them so much, we are thinking of getting another freezer. They last a long time - I've had some probably 5 years - once the outside has any damage I replace them.
Review: Cold-holding bricks - First introduced to these when I received one of these brix with an online shipped food order. Did such an amazing job at maintaining freezing temperatures that I sought out more of the product. Soooo glad I did - they came in VERY useful when my refrigerator failed recently and I was forced to put everything into coolers for over a week. Even with frequent opening of the coolers, these brix stayed frozen and kept things cold. By comparison with several other refrigerator packs in use at the same time, they did the best job over the ten days. The 9x4" size of the brix are good size, very solid and not floppy even when not frozen. They are easy to fit in large coolers. Almost any freezer pack can work for a few hours but these brix easily held up for 18-20 hours and were still really cold and quick to refreeze. The brix easily stay frozen for 2-3 days when the coolers weren't opened frequently and searched through.
