    Not really impressed with this mug. First, I think it should hold more and second, the highest temp is 140 degrees...I prefer higher. That said, it is built solid and after several weeks using it, no problems

    Easy for my mom to use after the app was installed. Heats to the right temperature and eliminates the burnt coffee on the stove.

    The cup works great, it keeps my coffee hot all day while on the coaster. The cup uses an app to let you configure your drink temperature and you can create profiles for drink types with different temperatures. But the android app is garbage. Read the reviews on the play store before you buy the cup. I had to restart my phone three times for the initial pairing to work. During the first week of usage I was only able to change the temperature once without having to restart my phone. I finally gave up and set the cup to one temperature and uninstalled the app. Overall I like the cup by itself and if you dont need to constantly change the temperature it works great.

    Over time the mug does not maintain the temperature set for the coffee. I think the battery is wearing out. Seems like it is wearing out awfully fast.

    Easy to use and keeps beverages warm. But if coffee was kept in it for awhile, it looses its taste and creamer in the coffee makes it turn bad. So I don’t use it with my coffee, and been using with tea and other hot beverages.

    I purchased the white mug. I was worried the color might show coffee/tea stains, but it does not. The lip is nice and thin, The mug will keep liquids warm for about 1.5 hrs., wish it was a little long, but I just keep the charger next to my work area. Just have to remember to place the mug on the charger and not on my desk. Overall I enjoy the warm cup of coffee. I little hard to justify cost for an average gift, but for a spouse, partner, or self indulgence very nice.

    Although i love this cup and its “on the go” features, the only thing i would change it how fast it heats up. It can take some time to get a warm cup of tea or coffee

    Great concept. We have two of these and one is malfunctioning after 2 years and customer support is horrific (slow and unresponsive). When working it’s a great product but definitely a luxury item. Glad to get rid of our other mugs.
