    Warms well. Battery is long lasting. No complaints at all. Only thing is that the mug takes a while to warm the water, but working from home gives me plenty of time to wait.

    It is nice to have such a cup to keep tea or coffee hot. But its reliability needs to be improved. There have been a quite a few times there is drink in the cop but the cup cannot turn on automatically

    This mug was a Christmas gift. They were very surprised to receive it. They also wanted to get it working immediately. I would say it was money well spent.

    This mug is the best for a camping trip. What I do is charge it before I go to bed and the next morning it stays fully charged… keeps my coffee hotter than Cameron Diaz.

    This is a great item for a person who pours a cup of coffee and drinks it only for the experience and not the caffeine itself. I bought this for my aunt and she loved it

    I've now purchased 3 of these mugs over the years (replacing them for various reasons). I now hate having to resort to using a regular mug.

    Love the mug, works as advertised. Only issue is the app doesn't work on certain newer phones (e.g. the S22).
