Product review (5 stars): Easy to make perfect ice spheres for anything from whiskey to Coca-Cola to water
Ice spheres are an awesome way to cool down a beverage.  They don't melt quickly like small ice cubes, but with a huge surface area on the outside, they cool the drink fast.  So you get a great cooling effect in your beverage without it watering down.  They are fun to put into everything.  We're not big drinkers, but my kids even loved having them in their water just for the fun of it (and yes, I realize you can't water down water).

This set makes the sphere freezing process simple.  You fill the plastic cup at the bottom to the fill line, put the silicon top over it, and put it in the freezer.  The convenient fill line ensures you don't overfill the sphere which can be a big problem with other moulds when you overfill them and it freezes into a weird blobby shape.  I got perfect ice spheres every time.  The ice can be a bit of a problem to release at the end, but a small run under warm water made it come right out.

Recommended tool for making perfect ice spheres.
