    I bought this mug for my mom for Christmas. She loves it. She has COPD and cannot get around to well. She makes three cups of coffee in the morning and then she pours them into her special mug as the day goes on. Every time she takes a drink of her hot coffee she looks at me and says “I love this cup”

    It worked perfectly, but the cup is too small. I need to refill all the time.

    The cup has been great other than a few software glitches. The cup went through a spell of randomly not working. Embers tech support had me do a hard reset which has worked for now

    Bought this mug for a Christmas present - had not even heard of it before its being asked for. Turns out to be an amazing mug. It is very well made and once you have the APP, it does everything promised.

    For the avid coffee drinker this is a must have. It’s amazing how many times I had to put my coffee in the microwave after letting it get cold. It never tastes the same. This cup keeps it the perfect temperature from the first sip to the last sip.

    Returned it because it was too small. Got the bigger one but I believe they need to make a 16oz. one.

    My wife received this as a Christmas gift and loved it! She ended up buying a second mug for herself to take to work. A note, though: we had some difficulty with the Android app (connectivity was spotty). The iOS app works flawlessly, though.

    Bought these as a gift for an upcoming wedding. Found the sale price and purchased 2 sets one for Holidays too. I purchased a set for myself last Winter and love them. Great buy especially when you catch sale!

    Little else I can add, other than to say that despite the price, I think whomever you buy this for they'll love it, even thought I would never buy one for myself. WARNING: not dishwasher safe! Wash it by hand always!

    Bought for my wife for when she works from home. She tends to get caught up with work and will forget her coffee. This will keep her coffee warm for when she remembers her cup. Nice little buy...

    The battery doesn’t last lining at all so if you want it to last all day it’s not for you.

    Seems silly to charge an extra fee for the charging base but either way it’s an awesome gift idea and works really well.

    Works as expected. One small quibble. If you want temperature higher than preset 130 degrees, you have to reset it each use.

    Cool concept but is flawed in ways that would have been easy to fix through software. Example: Cup only heats when it detects liquid. It'll only detect liquid if liquid is warm. So you can't warm up your coffee if the cup ran out of battery (which happens very fast).

      Hi Matthew, thanks for leaving a review and sharing this! The Ember is meant to stabilize an already hot drink down to your set temperature and not heat one up, so for best results, we do recommend pouring in hotter than your set temperature (around 165°F and above). We do appreciate this feedback and can certainly share this with our team! Ember

    I bought the 2 pack. I have 1 at work and one at home. I wish it would warm up the tea or coffee a little sooner than it does. I Also wish it lasted a little longer. But over all I love it.

    Works great, heats for about an hour per charge. No more reheating drinks in the microwave!
