Review on Samuelworld Large Sphere Ice Mold With Lid, 4 X 2.5 Inch Ice Balls - Food Grade, Easy To Fill Round Silicone Ice Tray, Perfect Spheres Craft Ice Maker For Whiskey, Cocktails, Christmas - Gray by Yasmine Sepulveda

I like the idea of these, but as you can see from the photo, you need to help it a little to get good results, at least I had to with the ones I got. Without adding the rubber bands to hold the silicone top down tight, they leaked to the point you didn’t really get a round ball of ice. I also found putting them in a pan kept any leakage from accumulating in your freezer. That said, adding the rubber bands only takes a minute so it’s not that big a deal for me.
