Never tried them with alcohol, but they make fantastic iced coffee slushies. The ice cubes are a bit of a pain you can just take them out and lick them off, then put them in a bowl. My daughter loves putting in chocolate milk, or lemonade, both work out great. For those that say they can't get them to work my response is...huh? Freeze cubes, put cubes in cup, fill cup to line with desired liquid refreshment, put on lid, cover hold with your finger (hole there for when you use soda pop) and shake like hell for 3 minutes or so. Done.
