    I enjoy keeping my coffee and tea warm for extended periods of time. I have two issues, one of which may be a user issue. I wish I could keep my beverages a little hotter than the mug allows. The second issue is the app is horrible. I have issues updating, and I have to reset the connection between the mug and the app several times a week. I almost returned the mug, but I have decided to live with the problems in hopes the Ember app will improve over time.

    I like it, it’s a great item to give as a gift. I only wish I didn’t buy it in the summer since it only keeps drinks warm.

    Bought the larger mug after purchasing the 10 oz. My wife likes to drink tea in the afternoon. She usually drinks it in a larger mug so I bought this one. She is very pleased with it and it keeps the tea hot till the last drop.

    The recipients of this gift are thoroughly enjoying it! I received one for Christmas as well and love it. I can take my time enjoying my coffee and each sip is as hot as the first. No more cold coffee reheated in the microwave.

    Always a warm latte! I never like the last sips of my coffee or latte when it’s cooled off. This cup remedies that! I absolutely love it!
