Really underwhelmed by this. If you're a person who likes your alcoholic drinks chilled but have a distinguishing pallet that doesn't want ice cubes in your drink (because apparently water changes the quality or taste and these weird dissolving rocks don't?), then this product is for you. Unfortunately, neither of those things apply to me. I don't drink much as I checked off on my BB profile, when I do I don't take ice, and if I did it wouldn't bother me to have ice cubes in my drink. I feel like this product only exists for people to feel eccentric or discerning. We have a word for those sort of folk where I come from. The same sort of word we used to describe people with sideways visors and ed hardy clothing.
