Product review (1 stars): Save yourself
The molds are very weak and squishy so the water does not freeze right the balls fall apart only one minute into setting it in the drink. I even had one split in have the minute I set it in the glass not dropped set. The water moves in the mold so much that they come out with extra stuff around the sphere not letting it set right. And they are very small. I will be springing for the extra cash for a good set until then my metal whiskey rocks will have to do. Thought that by buying these I would save money not the case wish I would have just payed extra like I always do and been happy.
