Promising review: "I bought these molds to make ice spheres to add to whiskey drinks and other concoctions served in an old fashioned glass, and they have been outstanding. They are durable, easy to clean, and they produce a sphere that is the perfect size for a standard old fashioned glass.
Because they take longer to melt, the ice spheres don't water my drinks down as much, which I appreciate both for alcoholic and non-alcoholic beverages. I have always hated watery soda, so I rarely put ice in it before I got these sphere molds, but now I can enjoy ice cold soda without it getting weak. If I am drinking an old fashioned, these spheres add just the right amount of water as they melt, mellowing the drink out without making it too bland.
Also, and this is important, my friends think they are cool. I don't know what it is about a large ball of ice, but people get oddly excited when you make them a drink with one. Some of the simple things in life are the most satisfying, and this is a simple thing that people get pumped about, which amuses me." —John H.
