    Does it’s job keeping the temperature steady. If there is just a little left in your cup remember to turn it off. Mine is discoloring at the bottom and haven’t had it a month. Otherwise good product.

    This is fourth Ember mug that I have purchased. This one works just as well as the others and keeps my coffee hot for hours.

    We are currently testing out the temperature controlled mug. We fired it up Christmas day. It seems to be function as promised. We may adjust the temperature up from the 135 degree setting.

    I bought this as a gift for my sister and was pretty skeptical about a mug that costs $100. She loved it and it works as intended! I would recommend to others.

    Bought this as a gift for my wife and she loves it! Be sure to use the base to keep it charged as you use it. The battery does not stay charged for long without it.

    Morning game changer. My coffee stays amazing and I never get that room temperature last ship shock when I'm focused on work and lost track of time with my coffee.

    This cup is one of the best inventions ever. I love this cup. It keeps your hot drinks hot and if they become cold, just sit the cup back on its base and set your temperature, it warms up again.

    EMBER is one of the best product created. I enjoy coffee and tea. This mug allows me to have a perfect cup of coffee from the time it's freshly brewed until its finished...from 10 minutes to 4 hours!

    My mom is constantly heating up her coffee in the microwave and this mug was a great solution. She wished the max temp was a little higher, but it definitely keeps her coffee steamy and good.

    Working from home means lots of coffee. I honestly haven’t had a cold sip of coffee in 7 months, and I’ve had a lot of coffee. Definitely a great little gadget. Customer service is also top notch.

    LOVE LOVE LOVE my mug. Once you start temperature controlling your coffee, it's hard to go back. The price is crazy, but it really is awesome. Value is in the eye of the beholder, though.
