    Everything was going fine until the unit just stopped heating and would no longer connect to Bluetooth. Missed the return date by 1 day. Great product as I have a travel mug and a copper mug that work great so this one has to be defective

      Hi there, the Ember mug has an expected battery life of around 80 min off the coaster, set at 135°F, and pouring in above the set temperature. However, there are various outside factors that can also contribute to the battery life. With that said, please feel free to head over to our support page and contact us if you have any other questions, we are happy to help! Ember

    Needs a little more Tweaking

    It a good ideal that needs a little more work. App says 148 degrees but does feel like it when like it after using the chef thermometer the temperature is actually 138° which is the case most of the time the temperature is always about 10° less than the app on the phone says it is. After this consistently happening I decided to return it for a refund.

    If i could, i would give zero stara. I am sure it is a great product but I did not get to use it as I ordered online and got it delievered and it looked like the delievery drivers were playing soccer with it. The box was smashed. I open the box and what to you know the bottom of the cup where the battery is was popped out and the light just stayed on the whole time

    HORRIBLE EXPERIENCE

    Very disappointed. The package arrived open, like an open box item, with signs of having been used before. But the product itself is really bad. It is impossible to pair it with an iPhone, I mean, after a week you might end up getting it done, but the process is incredibly precarious. Then the battery last only 1 hour and it takes over 5 to charge. I really don't think the people behind this product thought this trhough.....if I can't keep my mug hot all day long, or at least long enough to finish my tea, there is no purpose to have a product like this. Bummer......totally and complete bummer......
