Tovolo Seamless Sphere Ice System, Compact, 2.5 Inch Crystal Clear Spheres - Set of 4 Molds,Black

Awful product. Tedious to fill then it leaks a lot of that water straight in to the freezer. I wish I’d tried it earlier so I could have sent it back.

Works as advertised. You can't leave them in forever. My freezer gets the cubes within 12-16 hours so I remove them around that time. There's a chance the plastic would break if you left it indefinitely. Cubes come out clear and square if filled properly.

This product works well to make clear ice (using tap water) and the size of the cube are perfect for a cocktail old fashioned glass. Been able to use this product again and again so far.The ice cubes are not clear everywhere throughout (unlike the photo on the box). There are always some oddities.The polystyrene is fragile and need caution when disassembling. Not sure how long it will last.

I've had the cube version of this for a couple of weeks now, and it's absolutely great. It takes a little getting used to, but now I can unload 4 cubes, reload, and have it back in the freezer in 10 minutes. It's slow to freeze, but I've found out that you don't have to wait for the entire unit to freeze, only the top 4 cubes. I can do two cycles a day easily. The only drawback I've seen is that it's not practical to use the bottom section for usable ice, so energy is wasted if you allow the freezing process to go full cycle. There's nothing like dropping a garlic stuffed olive into a cocktail glass, adding a cube, filling with Bombay Sapphire, whispering "vermouth" over the top of it, and serving the best martini in the world to a guest. Even better if you keep the Bombay in the freezer as well.After using it for a couple of months, I love it. But it needs to have the fill tube reinforced. It's fragile, and if you bump it and cause even a small crack at it's base, you'll have the reverse of the China Syndrome. A quart of water will flow down to the bottom of your freezer and solidify. Also, much easier to harvest the frozen cubes BEFORE the bottom section freezes. Experiment to find out how long it takes just the 4 cubes on top to freeze. In addition, for loading, it's easier to put the thing together while it's wet, but better to fill and add the styrofoam when it's dry. Don't spill water between the plastic and the styrofoam or it will freeze and make harvesting the cubes more difficult. Another negative point is, that while 1 cube is absolutely perfect for a martini, you can't use a martini glass for it, lol..

Tried a bunch of ice cube trays/systems to make clear ice.This is the only one that does the job.Well designed, easy to use. Love it.

While I love the Tovolo 81-22904 King Cube Ice Mold System for its ability to create large, clear ice cubes that melt slowly and keep my drinks cold for longer, it's important to note that it can be fragile. When trying to remove the ice cubes from the mold, especially when they are frozen, the mold can crack or break. I have personally experienced this and unfortunately had to replace the mold. However, with careful handling and patience, I have been able to successfully create many large ice cubes with this system. Overall, I still recommend the Tovolo 81-22904 King Cube Ice Mold System to anyone looking for a high-quality ice mold, but just be aware of its fragility and handle it with care.
