Balls of Steel - Whiskey Drink Coolers

I really like these. Not just for the gag value. Or for the self-interest of donating to a place that is researching to save all of our balls.They're pretty good for cooling small amounts of beverages. This is important to bear in mind. Small amounts. For the sake of experimentation, I used these to cool other, non-alcoholic beverages. I can imagine my physics teacher laughing at me.The high thermal conductivity of steel causes it to absorb heat rapidly from your drink, so it cools down quickly. If you're only drinking a small quantity of a fine beverage like bourbon (~2-4 fl oz), this product will perform as you expect it to. The issue I had is that I neglected to remember that the specific heat (heat capacity) of steel is kinda low. Even with whatever they've put inside, it will not absorb anywhere near the kind of energy that ice cubes would. So don't try to use them for cooling your tea like I did. You'll just end up with two very hot balls of steel.The included tongs can come in handy, as cold bare metal fresh from the freezer will stick to your skin. Also, they need to be _gently_ placed into containers made of glass or you will break those containers.

My husband and I gifted a set of these to our son for Christmas. He had asked for a granite set of chillers, but after doing some research, we opted to purchase these instead. Our son uses them for chilling whiskey, but they would work for most beverages I imagine. These are especially useful when drinking something you don't want diluted by melting ice cubes or want to chill to a specific temperature range (like whiskey). Where granite would be somewhat porous and may absorb whatever liquid it's put in to chill, this isn't an issue the steel. The round shape rolls around nicely in the glass as compared to square ones, and they come with small tongs to remove the balls when your beverage is chilled before drinking (think potential for chipped teeth). We will definitely purchase more. Terrific gift!

They work as well as another set of 'Stones' I bought at the same time. Great to chill a drink without watering it down. My only complaint and probably my fault for not realizing it is that they are pretty small. If you are in 100degree temps and need to put 2 in your drink then you are out until they refreeze. Again my fault as pictures clearly show 2 small balls in the glass. But hey work so no complaints on the product.

I thought the balls would be bigger. I have yet to use them.

They are much smaller than the pictures seem to indicate. Was hoping that they could be used for 2 drinks at the same time but due to the size both are needed to cool one drink.

I bought these for my boyfriend (casual bourbon drinker) and he said that he would still almost prefer ice cubes. He doesn't necessarily like that ice cubes add water, but he prefers his bourbon a bit colder than the BOS offered. Otherwise, he said they were nice and still cooled pretty well, plus they looked cool.

Nickel size instead of golf ball sized

Ice, even big cubes, melts and waters down my bourbon. Unacceptable. Tried whiskey stones. They help but not great. These things work much better. I use four at a time in my drink. A little pricey but that is what gift giving occasions are for.

Nice concept,clean and elegant but they don't keep your drink cool for very long.

Christmas present for the man who has everything. I read a lot of reviews on various whisky stones made from various marerials and these came up the best. These we weren't the cheapest but my boyfriend is very impressed that he can have his whisky cold without it being over diluted by ice.

Bought these for my partner for christmas and he loved them. They really do keep a beer cool for quite a while. And the donation to the charity is a nice touch too!

They do not even stay cold for 30 seconds. Complete waste of time and money after so looking forward to using them. Not worth their weight in scrap metal..... SOOOOO disappointed!
