    Excellent cup. Keeps my coffee at desired temp for about an hour. Now all I need to do is get my wife one so she can give mine back.

    This cup keeps my coffee at the perfect temperature. It's pricey, but totally worth it if you hate lukewarm coffee and are too busy to sit still.

    It works as intended and keeps the coffee hot. However in my opinion it’s not worth $130 so I returned it.

    My mom had trouble with the mug- however Best Buy returned the mug with no hassle so with that in mind, even though it wasn’t “our cup of tea” we still go 5 stars because Best Buy is the only place where we go to buy electronics for our family. Thank you Best Buy you are the Best!

    My wife loves this mug. Use it everyday. She’s busy so taking a few hours to drink coffee is the norm so this keeps it hot.

    Best idea but...

    Nice, but only stays charged about 90 minutes. So unless you’re sitting right next to the charging pad, the coffee won’t stay warm forever. And it’s such a small serving of coffee even in the bigger cup, that it’s long gone before it has time to cool down. Neat concept, but larger cup and longer batter life would be better.

    No, I would not recommend this to a friend
