The whole "chill without dilution" claim actually holds up—I poured a hot pour-over through it and got a properly cold, strong iced coffee in under two minutes. It's become my daily summer ritual.

I was skeptical about “instantly” but my black drip coffee went from steaming to properly iced in under two minutes, and the flavour stayed bold instead of turning watery. Perfect for when I crave iced coffee but forget to brew ahead.

Took my hot pour-over from steaming to properly cold in under two minutes, and the taste stayed exactly as rich as the hot version. No watery mess from melting ice cubes. This thing's earned a permanent spot on my counter.
