Review on SUMPRI Ice Cube Tray, Silicone Sphere Whiskey Ice Ball Maker Mold With Lid [Set Of 🍺 2] Large Ice Cube Trays Novelty, Big Square Ice Cube Mold For Cocktails, Reusable & BPA Free (Blue) by Russell Anh

I feel like this is a poorly designed product that was rushed to market. Ball trays are poorly designed. They don't seal well and leave a trail of water in the freezer. The spheres themselves take on an irregular shape due to the separation of the two mold halves, and their physical size is about the same surface area as a standard ice cube, making them a poorly designed novelty. The square dice tray is a bit better, it's bigger but still leaves room for improvement. The actual silicone material also has to be processed. It took one wash and three icing cycles to get rid of the chemical production smell. Don't waste your time, money and effort on it
