Product review (5 stars): Big cubes are practical and fun
Sturdy enough to fill and put in freezer door. Compact. You get a lot of ice relative to the size. Will stack on a previously frozen tray, but you can't really stack two unfrozen trays unless you offset them carefully. Not hard to release the cubes. Cubes are square but with bottom corners slightly cut away. Filling with boiled water makes clearer cubes. Great in scotch glasses and pitchers. The cubes last a long time in a drink or to keep food cold in a cooler (in zip baggie). Very nice product. Good service.
