After breaking countless plastic ice trays, I figured I would give these a shot. They are really neat, and the silicone is unbreakable. The ice balls are much larger than the average tray cubes, which is great since it doesn't make as many, you only need 1. I find the water gets through the mold when filling, and the tray gets messy trying to get the ice out after. But its not a big deal, we use the smaller ice chips between the molds as well anyways. The molds are similar to cake pop molds, I am not sure if they could go in the oven though, will have to look into it first, but would be cool to have a dual use mold!
