    The mug itself works great; it's the app that is flaky. I brought the mug on 6/8/2021 and the app just let me connect to it thru my ph. last saturday SMH

    OMG!!! This mug is a game changer. A must have for those who love to keep their drinks hot and get distracted a lot. Never heat your coffee up in the microwave again.
