    I really love this cup! I like to sip on my coffee and this keeps it warm without burning. My only issue is that the end on the cord is obnoxiously large so I have to keep the charger plugged in where nothing else is.

    It does exactly what the inventor made it to do. You must do exactly what the instructions tell you to do.

    The idea is best but the item is not. It loses charge fast and when put back in the charging coaster with coffee... the coffee changes flavor.
