Review on LiyuanQ Ice Cube Trays: 2-Pack Large Silicon Ice Cubes Mold and Ice Ball Maker with Funnel and Lid - Perfect for Whiskey, Cocktails, Juice, and Parties (Black & Grey) by Amanda Dunn

No clogging. As you start filling the "balls" the water will begin to flow down the sides. You can watch the water level drop. lame! And it gets worse when you try to pick them up to move them. water is everywhere. You can maybe get 1/2 scoop of ice cream from these things. And since there was water everywhere when you put them in the freezer, there are chunks of ice everywhere when you try to open them. If you buy this awful product, try to fill it with water while it's on the plate. They'll still leak if you fill them up, but at least it won't get any worse if you take them and put them in the freezer. The only good thing I can say is that the material they are made of seems decent.
