True Cubes Crystal Clear Ice Cube Maker, 4 Large 2" Cubes
True Cubes uses directional (top-down) freezing inside an insulated mold to make crystal-clear 2" cubes, fixing the one flaw of a big-cube tray like the Tovolo King Cube: cloudiness. It is a real aesthetic upgrade, but slower, bulkier, lower-yield, and usually needs the cloudy base trimmed. Clarity is mostly cosmetic; a same-size cloudy cube cools a drink nearly the same.

What have experts found about the True Cubes Crystal Clear Ice Cube Maker?
Every claim below is tied to a source you can open, quoted verbatim — how we research picks.
-
“The outside of the cube freezes first, and when the interior solidifies, those gases have nowhere to escape to.”
Ice turns cloudy because it freezes from the outside in, trapping dissolved gases in the center.

“freezes a tank of water slowly, from one direction, keeping the surface gently agitated to make sure not a single air bubble is trapped”
Commercial clear ice is made by freezing slowly from one direction so no air bubbles get trapped, the same principle these insulated home molds use.

“By forcing the water to freeze in only one direction—from the top of the cooler downwards—it will push away the trapped air in layers, leaving behind clear ice that can then be broken down.”
Directional (top-down) freezing pushes the trapped air out, leaving clear ice.

Buy it if
- Hosts who want whiskey and stirred cocktails to look bar-grade with flawless clear rocks
- Gift buyers shopping for a whiskey lover who values presentation
- Anyone already using a big-cube tray who is bothered only by the cloudiness
- Slow, planned entertaining where a 24-hour freeze cycle is no obstacle
Skip it if
- Anyone who just wants cold drinks and does not care how the ice looks
- High-volume or spur-of-the-moment entertaining that needs lots of ice fast
- Small freezers where a bulky insulated mold that yields only 4 cubes is a poor trade
Is the True Cubes Crystal Clear Ice Cube Maker worth it?
A genuine fix for the King Cube's one weakness, cloudiness, via directional freezing, and the clear cubes look the part. Just know you are paying in time, freezer space, and yield for a benefit that is mostly cosmetic; a cloudy cube of the same size chills nearly identically.

- Clear-ice maker vs. a cheap big-cube tray like the Tovolo King Cube: is clear ice actually worth it?
- For looks, yes; for performance, barely. Both make a 2" cube; the True Cubes one comes out glass-clear, the Tovolo cloudy. But melt and cooling are governed by the cube's surface-area-to-volume ratio, not its clarity, so at the same size they chill a drink almost identically. Pay for the clear-ice maker if presentation matters to you; the cloudy cube performs nearly the same for a fraction of the effort. Source SevenFifty Daily ↗PUNCH ↗
- Is clear ice mostly aesthetic, or does it really melt slower?
- Mostly aesthetic, with a marginal density edge. Clear ice has less trapped air so it is slightly denser and can melt a touch slower, but the effect is small next to cube size and shape. Treat clarity as a presentation upgrade, not a meaningful dilution fix. Source PUNCH ↗SevenFifty Daily ↗
- Why does my freezer ice come out cloudy in the first place?
- A standard tray freezes water from all sides at once, so dissolved air and impurities get driven to the center and frozen in with no way out. That trapped gas is what scatters light and looks white. Freezing from a single direction instead lets the air escape. Source SevenFifty Daily ↗
- What are the real downsides of a directional clear-ice maker?
- It is slow (18-24 hours per batch), low-yield (4 cubes), bulky in the freezer, and the bottom cube usually has a cloudy base you trim off. If you entertain often or want ice on demand, a fast-cycling cloudy big-cube tray or a standard tray is more practical. Source PUNCH ↗
