Kollea Fathers Day Whiskey Stones, 8 Packs Stainless Steel Whiskey Chilling Rocks, Reusable Ice Cube for Drinking, Cool Birthday Gift for Men Dad, Boyfriend, Beer Lover, Bourbon, Scotch, Gin, Beverage

They work very well. I really like the simplicity of these cubes and certainly do not miss filling and refilling ice cube trays, not to mention the extra space my freezer. I use mine in juices and soft drinks. Absolutely recommend this product!

These really work and are easy to clean and store away. They obviously do not water down your drink, as they are not made of water. They get cold from the freezer quickly and stay cold for a good amount of time. They also look cool in a drink.

Love these cubes! Why water down your drink when you can use these cubes and get your drink chilled for an extended period of time?

The amount of people I see who have rated these down because they don't cool a room temperature drink is astounding. They're not meant to make a room temperature drink ice cold. They're meant to help keep an already cold drink cold. If you know that and use them in that way, these are great. They really do help prevent a cold drink from getting too warm too fast. But if you buy these with the expectation that you can drop them into a warm drink and they'll make it ice cold, you'll be sadly disappointed. In short, great product when used for its actual purpose.

I like the fact that the drinks dont get diluted but the cooling factor is not as good as real ice. The drink does get cold but its not “ice cold”Expected a bit more out of this but I am okay with it.

I bought these for my son for Christmas. They were smaller than expected but cooled off quickly. My son liked them but forgot them at my house. So now I have a set and he has one for his house (since easier to send via Amazon than to pack and mail to him). Win win.

Excellent Quality for the price!
