    This was a gift for my wife, although initially she gave me a bad look, now she won't leave it alone, she loves the mug and to be able to enjoy hot coffee all the time.

    Does a good good. Used with coffee, tea and cocoa. The downside is having to charge after each use. My morning coffee usually uses a complete charge (about 2 hours).

    Good coffee mug. Keeps coffee warm for extended hours as described. Only issue is coffee at the very end can taste a little burnt from the heater. Overall good mug.

    I love it. I don’t drink my coffee immediately. It sits on my desk and I sip at it. By the time I get to the bottom, it’s cold as ice. My new Ember mug keeps my coffee warm to the end. Very happy!

    Just a tad too small and pricy

    I couldn’t keep it. It’s ultimately too small for my size of coffee cup that I usually use. I really wish that it could’ve been USB-C and not a giant AC adapter that I have to find a spot for on my desk. Probably could not be a USB-C because of the power needed to charge the mug.

    No, I would not recommend this to a friend

    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.

    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.

    Looks great and does it's job. But be careful about about leaving a sip in the mug for a longer time, it will evaporate and leave a tough stain
