Product review (5 stars): Great Design, Fun Alternate to Standard Ice Cubes
Ice balls, who knew they could be so much fun! I've tried whiskey stones, non-melting ice cubes, etc. Many of these don't chill a drink to enough of a level. However, ice balls add a great chill, with slower water melt and more versatility. This set of molds are easy to use, with a two part set. You fill it through the top (distilled water can produce a more clear ice) and because it has a larger base, it is less likely to get knocked over in a freezer. Removal was really easy, a quick run over water and a little push and out it pops. It is just the right size to sit at the bottom of a drink glass. It melts slowly so your drink stays undiluted for longer.

There are lots of other uses for these as well, Put some fruit in the middle and then freeze it. You could freeze juice inside or any other beverage that you want to slowly diffuse into another drink. Great for parties, punch, or whatever.
