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.

These are the first "whiskey stones" I've really liked-- each stainless steel is filled with some sort of non-toxic gel that holds the cold even longer than the steel (or ice) would. [Since the gel never touches the drink, its toxicity doesn't worry me much. Some of the stuff I drank back in my youth was reasonably toxic,anyway.] The product comes as a small tray with eight stainless steel "ice cubes" and a pair of metal tongs, for handling them (Photo #1). The whole tray can be slid into your freezer-- the company, Aerb, says three hours before use, but I just leave them there (Photo #2).I didn't really appreciate 'ice tongs' before-- if you pick up an ice cube with damp fingers, it's no big deal. If you pick up one of these, it'll adhere (painfully) to your finger tips. There is probably an easier way to learn this-- such as reading it in this review-- than the method I chose. The tongs, incidentally, work by grabbing either the corners of the cubes or the flat edges-- after experimenting, I find the corners easier (Photo #3).I've found that a whiskey glass best uses two or three cubes (Photo #4, with water instead of whiskey for visibility's sake), and the larger the glass, the more cubes you need. This seems obvious, but I've learned that stating the obvious rarely hurts. Equally-- and far more importantly-- obvious: do not do as many do with ice cubes, and try to suck on one. It's way too cold, and the pain you'll cause yourself (or an unsupervised child might cause himself) should not be experienced.I'm going to give these five stars, as the only negative to these was my wife's complaint-- she likes crunching ice cubes with her teeth, and these would result in her crunching her teeth with ice cubes. Not cool. Cold, but not cool.Recommended.[I was sent these for the purpose of evaluation and honest review.]

These are great and presentable. It keeps drinks cool but not as cool as ice would. But it still does a great job. If you place these into hot coffee, it takes a while to cool down. I add in an ice or two to get my drinks a little cooler when it’s hot and then add these to keep it cold.

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’m not a big cocktail or liquor drinker, but am passionate Ice Tea!I keep my ice tea refrigerated, but because I sip at it all day in a large insulated container, it turns into a tea flavored water before I’m done with it. I bought 4 sets of these beauties! I use 2 sets in my insulated cup and keep 2 sets in a baggie along with another insulated cup (separately) in the freezer, and change them out after about 6 hours. It keeps my tea near frosty!I love that they are stainless steel. I had some plastIc ice cubes, but they didn’t last very long. These stainless steel cubes last so much longer. They stay icy cold for hours and keep my ice tea at the temperature I like.I use fresh lemon in my tea and they clean up beautifully. I simply add a drop of liquid dish soap to my cup, add water, and shake it up! I rinse them well, drop them back into my quart size freezer bag, and put the in the freezer.These are a perfect gift for everyone! Who doesn’t like an icy cold beverage. They are also perfect for milk drinkers who love it COLD! Soda drinkers! Yes please! And the container it comes with! Classy!I highly recommended this to my family!
