Review on Whiskey Godmorn Stainless Chilling Reusable by Vedavyas Fleming

Partially hollow spheres. When I move it I hear some liquid inside. However, it did not cool the drinks. I used a thermometer to check the temperature before and after inserting the steel balls. The temperature of the 8-ounce drink dropped just 5 degrees. This is after it has been placed in the freezer for more than 24 hours. I think balls are just bad stuff. If they were solid, I believe they could do better. Not worth the trouble.
