    Ember Hot Cup

    It took a while to get everything working properly. The directions are confusing as they give a line of instruction and then repeat it in numerous languages. The combination of yellow English instructions with white paper are hard for older eyes.

    I ordered this cup IN November 2023. I received an update notification, after the update my cup has not worked since.. This was on 1/17/24. I have sent three emails to Ember customer service for help . After I sent them a pic of the bottom of my cup (showing serial number) no one has reached out to me. I cup does not heat anymore.

    Great idea in theory, however after a couple of weeks we now have to reset the Bluetooth connection everytime we use it and the return policy ended. 20 days into owning this and it's just a headache.

    The mug itself is great but after only a few days, the connection to the mug via the software is non existent. Can be re-paired on another phone but eventually to the same results. Not satisfied.

    While it did exactly as advertised the 145 degree temperature was not hot enough for my wife. So if piping hot hot or tea is what you desire then this may not serve your need.
