Kollea 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, New Year

These stones seem capable of keeping a drink cold. I have found that adding about 1/2 of an ice cube along with the stones is what is needed to get the temperature down in the first place. This works well for whiskeys that need a little water to bring up their best. One could also keep the beverage in the refrigerator to start with. Then the ice cube would not be needed.

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.]

We bought these for our boss’ birthday. He can be a difficult man with particular interests and requests but these seemed like a great value for the money. We appreciated their design and quality.

Not bad! Could provide better cooling! You do have to stir the drink really well for it to cool down properly! Doesn't last as long as some people report! But they do look great!

These work well enough! If I had to critique them, I would say that they do not stay cold as long as I would like. Then again, normal ice just melts and dilutes your drink, so I guess I can't complain too much. This seems like a limitation of physics rather than product quality. For those worried that it might add a metallic taste to your drinks, I have never detected one

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.

These were a Christmas gift, well stocfking stuffer, for my husband and he loves them.

Works good for people who don't want a watered down drink.

Bought this for my husband he liked it

Very happy with the product. Having a case to hold them in the freezer as well means they don't get easily scratched. Little tongs mean you don't have to handle them after you e washed them and popped them into the plastic case. Delivery time was adequate.

What I likes: - Fast shipping It only takes less than a week to arrive. A+++++ - Premium stainless steel The material quality is premium. It’s a little surprise when I touched these cube. I used to scare of these cubes because of its quality but I’m totally happy with these items. Give me a luxury feeling. A+++++ - Freezing I put these cubes into a fridge and it’s only taking around 1 hour to be ready. A+++++. What I dislikes - Price I wish I can have more ice cubes with a cheaper price :-(. But you get what you pay. Overall: A+++++

الحلو في المنتج انه يحافظ عالبرودة ولا يغير من طعم المشروب فإذا بتضيفه لأي مشروب راح يبرده لك لكن لا تضعه في المشروب لانه يثقل عليك حمل المشروب و وصعب تحريك المشروب لكن اقيمة ٥ نجوم لتأدية الغرض ؛ انا استخدمة لتبريد القهوة لكن تقدر تستخدمه لأي مشروب بدل الثلج لانه الثلج ممكن يذوب و يخرب طعم المشروب

A few of the cubes came with the colouring already rubbing off but otherwise very solid.
