I absolutely love these ice cube trays. They work so well for anything from water to juices. The best part is the blue no spill cover. This cover makes it so easy to transfer trays to the freezer without any spills. What a great idea. Believe it or not, I can completely turn the ice cube tray upside down and not one drop of liquid comes out. Another great feature is that you can easily remove the blue cover for easy washing and to just use the ice cube trays. I bought 2 of them and I am sure glad I did. Highly recommend this product.
