3 Pcs Large Round Whiskey Stones Spherical Reusable Stainless Steel Ice Cubes Golf Ball Whiskey Stones Balls Metal Ice Balls Gift Set for Red Wine Scotch Whiskey Bar Beer(40mm Round shape)

The media could not be loaded.  I purchased these specifically for use when needing to cool down my freshly pulled espresso shot when I make my iced espresso drinks. Leaving the shot to sit causes it to "burn" which in turn takes away from the flavor. I just drop one of the balls in as soon as I pull my shot, and it cools it down to prevent burning. Perfect for my needs!

These will keep several drinks cold before needing to be refrozen. I would definitely recommend these stainless steel cubes because they are easily cleaned and stay cold longer. However I would recommend buying the square shaped ones instead of the round ones; the round ones roll around and tend to be noisy.

I use them for my espresso shots to make ice coffee cools it down very quickly

If you're buying it for yourself, yippee. If you purchased as a gift, boo. The stones come in a plastic bag not a box which makes the product look cheap. Doesn't even say stainless steel on the bag.

These are hollow metal spheres (they'd be awkwardly heavy otherwise, might be more of a threat to the integrity of your glass) but they are filled with fluid -- feels about 40% full? -- so their heat capacity is higher than a hollow steel ball would ordinarily have. Great with cocktails -- no metallic aftertaste I can detect -- and for soda they seem able to cool down more than one 8oz glass. Downsides: they are huge, and they will roll around in your glass -- side to side, and also up against your nose when you are emptying the last of your drink. All around, these are great.

I don’t have to worry about accidentally swallowing the large size! I will be buying more of these for gift giving! This size stays cold a long time, love them! I noticed people complain about not having a container. All of mine conveniently fit in a 16 oz. OM deli turkey slice containers.

These work really well, don't flavor the whiskey and look cool. Would have preferred if they came in a box to keep in the freezer

I keep my balls in the freezer and use them almost everyday to keep my iced tea cold all day in a thermal mug.
