TINANA Diamond Ice Cube Tray: Crystal Clear Ice Maker - Large Cube Maker for Whiskey, Cocktails, Bourbon - Diamond Shape

Produced the clearest ice I’ve managed so far with multiple methods. People here and other review sites have complained that the instructions (such as they are) refer to a water “fill line” that can’t be found. This line is actually a *vertical* groove in the middle of the bin - Fill to the bottom point of that groove.

Is really good but could be better to remove from the inside. Really hard to remove after the ice been formed.

This gizmo works great! We chose the 2 ball ice maker, so as to not take up too much room in the freezer, but you do you. Came up with crystal clear ice on the first try. Now, we used filtered water, so can't say how well tap water would work. The instructions insist on 24 to 30 hours freeze time - after 30 hours, it turns into a pumpkin? Also, we're gonna check what happens if we don't wait the full 24 hours... it'll burst into flames? And what about food coloring? the possibilities are endless!

I really like these clear ice cubes. I wish they were bigger. They do look like diamonds. And doesn't take up too much room in the freezer.

I’ve used directional freezing to make clear ice for years that I would then cut into large cubes or spears. I knew I couldn’t cut a diamond so I bought this and it is PERFECT
