I received the Oxo ice cube tray in the mail and immediately started using it. I like how the tiny ice compartments have space between them rather than being directly next to each other. I think it helps keep the cube whole as you are trying to get it out of its compartment. The silicone top is a good idea once it is in the freezer. However, when I filled the tray, the very outside edge had water in it. Once I put the silicone layer in place the water in the edge spilled all over me. The quality of the plastic was significantly better than other ice cube trays. Some trays are not durable, but this was thicker plastic.
