Ember Temperature Control Smart Mug 2, 14 oz + Charging Coaster Bundle, White

Why it's worth it

A temperature-controlled 14-ounce mug with its own charging coaster, so a cup stays exactly as hot as you set it. It's the rare luxury gift that gets used before 8 a.m. every day.

This solves a small annoyance that happens every morning, which is why it earns its price. Set the temperature in the app, pour, and the coffee holds there. Ember says the Mug² keeps a set temperature for up to 80 minutes on a charge, and it sits on its coaster indefinitely. CNET rated it 8.5 out of 10 and called it the best smart mug on the market.

The couple this suits is specific: one of them nurses a cup for an hour while the other finishes theirs in ten minutes. The slow drinker is the one who's been reheating coffee in the microwave twice a morning for years. Owner feedback tends to come from exactly that person — retirees, remote workers, anyone whose cup goes cold on the desk between calls.
