Our review
If you live in your 30–40oz tumbler, this ice mold is the obvious upgrade — 4.3 stars across more than 2,000 ratings. Instead of a handful of small cubes that melt fast, rattle, and dilute your drink within the hour, it makes one tall hollow cylinder of ice sized to drop neatly into big tumbler cups. Because a single large piece has far less surface area, it melts much more slowly and keeps iced coffee, water or a cocktail genuinely cold for hours, and the hollow centre means you can pour your drink straight down the middle. You get a 3-pack of soft silicone molds with snap-on lids, so you fill them, seal them to keep the water in and freezer smells out, stack them, and later peel the silicone back to pop the cylinder out cleanly.
Honest expectations: like all silicone ice molds, tap water freezes slightly cloudy in the centre, so for crystal-clear cylinders you'd use filtered or cooled boiled water and freeze slowly; most people are happy with the near-clear result. Seat the lids properly and fill to the line or they can leak a touch as the water expands, and give them a wash before first use to clear any silicone smell. Check the cylinder size against your specific tumbler — it's made for the popular 30–40oz cups, but very narrow or oddly shaped tumblers may differ. For keeping a big drink ice-cold without watering it down, it's a cheap, satisfying win.

FAQ
Why a cylinder instead of cubes?
A single tall cylinder has much less surface area than several small cubes, so it melts far more slowly and keeps a big tumbler drink cold for hours instead of watering it down.
Will it fit my tumbler?
It's sized for the popular 30–40oz tumbler cups. Very narrow or unusually shaped tumblers may differ, so it's worth checking the cylinder dimensions against your specific cup.
Can I pour my drink through it?
Yes — the cylinder is hollow, so you drop it in and pour your coffee, water or cocktail straight down the centre.
How do I get clear ice?
Out of the box it's near-clear; for crystal-clear cylinders use filtered or cooled, boiled water and let it freeze slowly, since tap water freezes slightly cloudy in the middle.
