XAMILE Round Ice Cube Tray for Freezer, Ice Ball Maker Mold with Lid Easy Release BPA-Free Reusable Ice Cube Mold for Whisky, Cocktail, Coffee (1 inch Ice Cubes)

These are the best ice cube trays I've ever used. They are easy to fill, and the lids keep the water inside on that difficult journey from water filter to freezer. No spillage. And the ice cubes are easy to pop out (I'd recommend you hold the trays under a running tap for half a minute to loosen the cubes). My earlier trays simply cracked when I tried to twist them to remove the cubes. It's too early to say how durable these are, but they look good and perform well.
