They're okay, they just don't really get as cold and/or stay as cold as I'd like. I still use them occasionally; just not what I'd hoped for. However the price was right for giving them a shot. No complaints there.

They did not keep beverage cold. When put in beverage as instructed the stones immediately became warm.

Got these as a gift for my step dad along with some whiskey glasses and he really loved them both

Not what I expected....doesn’t chill much. Have do larger stones to make a difference.

Compare with the Ice, The biggest advantage of the chilling stone is that is recyclable. It is so cool because the stone has the same function with ice.

Bags a little small

They did not work as promised. Was highly disappointed. They did not keep drink cool.

Great gift!! Slightly smaller than I expected and the texture is slightly rough. Stays cold as expected.
