Ember Mug 3 (14 oz) vs Ember Mug 14oz Smart Mug

Both are Ember 14 oz smart mugs, so the choice comes down to generation. The Mug 3 is the current model: on-mug temperature control, a sliding lid that stretches battery life past three hours, top-rack dishwasher safety, and a redesigned charging coaster. The older 14 oz Smart Mug works the same way at its core but is hand-wash only, lacks the lid, and uses the earlier app and charger. Owners of both praise the heat retention and 14 oz size; complaints center on weight, short battery at high heat, and a finicky coaster. Buy the Mug 3 unless you find the older model and mainly want the warming function.

• Choose the Ember Mug 3 if you want the current model with on-mug controls, a lid for longer battery life, and dishwasher-safe cleaning.
• Choose the Ember Mug 14oz Smart Mug if you want the original Ember experience and can hand wash it and live without the lid.
