- Honest reviewThe catch, not just the hype
Why this gift works
It heats your coffee or tea to an exact temperature you set in an app, then holds it there - no more reheating a mug you forgot about, no more scalding first sip or lukewarm last one. It looks like a sleek matte mug and quietly does one clever thing extremely well.
It is a proper splurge gift for the coffee obsessive, the work-from-home desk warrior, or anyone who lets their tea go cold reading emails. The kind of luxury they would never buy themselves - which is exactly what makes it a great gift.
Who is this gift for?
Great for
- Coffee and tea drinkers who let a cup go cold
- Work-from-home and desk workers
- Someone who reheats the same mug three times a morning
Think twice if
- They drink their coffee fast anyway
- They need a travel mug for the commute
- The budget is tight - it is expensive for what is still a mug
The catch
The battery holds temperature for a bit over an hour off the charging coaster, so it lives on its coaster at a desk - it is a desk mug, not a travel mug, and the price is steep for what is still a mug.
Skip for someone who drinks their coffee fast anyway, or who wants a travel mug for the commute.
Worth knowing before you buy
- Off its charging coaster the battery holds heat for a bit over an hour, so it is a desk mug, not a travel mug.
- Hand-wash only: it should not go in the dishwasher or be submerged.
- The temperature is set through the Ember phone app.
Why we like it
- Holds coffee or tea at the exact temperature they choose - no reheating
- No scalding first sip and no lukewarm last one
- Looks like a sleek, plain mug and does one clever thing very well
- A luxury most people would never buy for themselves
Questions people ask
You set a target temperature in the Ember app and the mug heats to it and holds it; on its charging coaster it stays hot indefinitely, and off it for the battery's life.
