    Does a great job keeping my coffee warm. But the app has given me nothing but problems. It keeps crashing, will not connect to my cup and will not let me update the firmware.

    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.
