OXO Good Grips Ice Cube Tray

My previous ice cube tray made basically cube-shaped cubes and the lid didn't lock onto the tray so it eventually warped and the bottom corners of several of the tray cubes cracked. So I thought this tray would solve these problems since it has half moon shaped cubes with no corners and the tray cover slides onto the tray to keep it in place. My biggest disappointments: 1. you have to carefully fill the tray to no more than 2/3 full. Otherwise, the cubes will get too big and freeze to the lid, making it difficult to slide the lid off to get the ice cubes. Then if you don't remove all of the frozen droplets on the lid, when you slide it back onto the tray, they will be scraped off and make a wet mess. 2. you have to carefully fill the tray because the water quickly and easily sloshes over the sides of the tray and makes a mess. 3. you have to place the tray on a flat level surface in your freezer because the bottom of the tray is rounded, not flat. Only the very tiny feet in the 4 corners of the tray are level with each other. I ended up having to perch my tray on top of a smaller rectangular container to keep it level while freezing. 4. the tray is larger than most ice cube trays and the lid is not rectangular so it takes up a lot more space in your freezer than most trays. I finally gave the tray away because I found a less expensive basic covered tray. It makes cube-shaped cubes and has a lid that doesn't lock or click onto the tray but I don't have to worry about water sloshing out as I'm filling it or the lid getting stuck or balancing it in the freezer.
