    Love this cup! With my busy mornings, me and my gf leave coffee sitting out all over the house. Love being able to come back to a warm cup of coffee without having to microwave the mug.

    I really like the mug but the app to control and update the mug is absolutely terrible. Haven't been able to update the mug since getting it but doesn't stop me from using it.

    This is my fourth ember cup. These things are amazing for the person who likes their coffee hot and sips on it over some amount of time. Cups work great, keep charge for at least 2 hrs usually and they look great.

    Battery life could be longer but almost makes the weekend coffee morning time. More than enough for shorter weekday time.

    Great item to keep coffee warm. Wish you could control the heat on the mug itself, but it is what it is. Plus the blue looks better in real life.

    I use this almost every day (as long as I don't forget to wash it). I love it so much that I started to buy them as gifts. The charge is relatively quick and the app is easy to use.

    Awesome, morning-life changing. Prior to getting the Ember, I was constantly microwaving my coffee to keep it warm. Bought one for my mother and she loves it too.
