Product review (5 stars): Easy to make and easy to extract perfect ice balls
I really like these molds.  Each one comes with a removable lid that comes off very easily.  You simply take the lid off, fill water to the fill line and put the lid back on.  Stick it in the freezer and you have perfectly round balls for drinks.

I've found that some of the molds are hard to work with when trying to remove the frozen ice ball.  With this one, you just turn run it under warm water for a short while and simply squeeze and it pops right out.

I highly recommend this ice ball mold.
