Product review (3 stars): Meh
I have to admit there isn't much difference in the size options, and the only real drag is that you have to put the ice into the freezer or it melts too quickly. The issue with that is, it's already started to melt, so you'll need an ice pick because the ice freezes together. It gets the job done, and probably is great for traveling but we hardly use it because it's just easier to buy a bag of ice.
