If you love iced coffee but don’t love the way the ice dilutes the flavor, you may be a cold brew person. Although, if cold brew is too acidic for you, there is another solve: Get this tumbler that chills any drink in five minutes.

Zoku Instant Iced Coffee Maker, $29.99

The Zoku Instant Iced Coffee Maker is a reusable tumbler that has a freezable inner core that chills drinks freaky-fast. First, you freeze the inner core for at least eight hours. Once it’s cold, place it into the sleeve, and pour your hot coffee straight in. Then, place the lid on, insert the straw, and wait — the inner core will chill the hot drink within five to seven minutes (less if it’s warm versus hot).

In addition to chilling full-flavored coffee, you could also use this to chill hot tea or room-temperature soda, cocktails, wine, water and more. Plus, it’s portable, so unlike other popular drink chillers, you can take it on the go and sip from it once your drink is perfectly cold.

The biggest downside Amazon reviewers point out is that they wish it was bigger. The cup holds up to 11 ounces of liquid. To compare, a tall Starbucks coffee is 12 ounces.

“I rarely write reviews, but this bottle is AMAZING!” wrote one Amazon reviewer. “This bottle turns hot coffee into literally iced coffee in minutes! Sometimes too icy! It does what is says — I love it ! I wish the inner bottle could be bigger and outer layer more sturdy, but overall an amazing product!”

The Zoku Instant Iced Coffee Maker is available on Amazon in four colors for $30 — about the price of the viral Stanley cup. However, can your Stanley actually chill your drink for you? Nope! It only keeps it cold. The Zoku is the only one that does it all.
