Dont get me wrong, It does what its supposed to do, it chills my drink without watering it down. I'm just slightly disappointed that they don't stay cold for long at all. Its enough to chill 2 drinks with the second being slightly cold. You have to wait about another two hours to be able to chill another drink. I like it but could be better.
cool as ice
These stones are excellent. They're the epitome of cool, and they keep drinks cool for a good long amount of time. Perfect for those who like to sip on fancy liqueurs or whisky, or whatever they like. Note that they are quite heavy, so if you plan to mail these to someone as a gift or even carry them on a plane, they do have some heft.
Not so chill
The idea and potential of this product made me really excited, but in reality, the stones don't cool my drink and don't take long to return to room temperature., even after cooling them for the (at least) suggested 4 hours. I would not recommend the product. :(
fancy schmancy ice cubes
I love the sleek black cubes! they are classy and in bourbon or just soda, they look great, they stay cold and dont sweat in your drink or dilute the drink. you will enjoy serving these, they come in a brown bag and I just keep them in the freezer ready to use.
My boyfriend and I absolutely love these little stones. Everyone who we have entertained loves them as well, they are a good conversation starter and keep your whisky cold for much longer than ice cubes!
