Title: Leaks, Freezes Hard, Does Not Heat Easily
Product review: I bought four of these to add to a cooler to keep beverages cold without wasting ice or the mess of melting things.It does that alright, however, every single one of them have begun to leak a very chemical smelling, off yellow liquid.I contained this problem with the quart sized freezer ziplock bags.Also, to heat up you have to fully cover in water, and the product doesn't get very hot. (I have only heated one, and that one leaks worse than the others.)Considering the price, I suppose the deal wasn't so bad, as I am able to use them for my intended purpose.
Would you say this review depicts the product in a flattering or unflattering light?
