Whiskey Balls Reusable Stainless Steel Metal Ice Sphere Cubes Beverage Chilling Rocks Whiskey Stones for Red Wine, Bar Beer, Scotch, Vodka Drinks

Work really well, and last a long time, very happy with purchase

It's easy to use, keep in the freezer in advance and use it when you need to

These keep my drinks cool without watering them down like the large round ice balls. They do not last vey long however so buy multiple if you have several drikers. I use one per drink. Do know these will not really chill a beverage like ice =.

I actually bought this for an unconventional reason. Got it to keep a bowl of cold water with a towelette to help bring my daughter’s fevers down whenever she falls sick. Keeps the water cold for hours and gives her so much relief! We don’t drink… But still SUPER useful!

These serve me perfectly keeping my beverage cold - I do not attempt chilling with them. I am a Dr. Pepper addict, so I have one of these in my YETI tumbler keeping my Dr. Pepper cold without dilution, while the other one is in the freezer getting ready for duty. These are so cold that a layer of ice actually forms around them in the tumbler. I use a glass straw, so when I draw a mouthful of Dr. Pepper with my straw right against that ball, I know that is as cold as it can be. A word of caution: use the tongs that are shaped to fit these for handling when they are cold. You can’t handle these with bare hands like you can ice cubes. I did that once before buying the tongs, and my thumb hurt for half a day.
