Perfect for my needs!
Definitely worth it! I haven't tried filling them with hot water, yet. I've mostly been using it as an ice pack to cool myself down, it being summer and all. It works great so far, and I suspect I'll love it even more come winter. The product itself is as advertised. Very easy to fill, a good size, and well made. And you get 2. Granted they don't come with covers, but I find it just as easy if not easier to wrap them in a towel.
