    I love my Ember mug. Bought it as a Christmas present to myself. The one thing that’s a little wonky is the battery indicator on the app. It will get stuck at 85% charging level for a long time and then eventually will push up to 100%. The battery works fine it’s just a wonky thing. Otherwise a great product. I’ve found that cheaper coffee tastes better when it stays a good temp. I usually set coffee at 138 and tea at 141. Love the ability to set and save presets at lots of temps. A quality item that is somewhat life changing. They are expensive though.

    5.0 out of 5 stars Ember vs Nextmug vs warmer *update*

    *update* !! The mug still works awesome and I’m super happy with it…PLUS…I discovered that my yeti travel cover fits in it!!! This extends the 80 mins of heat to MOST OF THE DAY (at 120F) if you can get ahold of a travel lid then you’ll love it even more!!!

    I tried out Ember, Nextmug and a coffee cup warmer. I chose Ember and here's why:

    (For context I am a busy mom and I drink one cup of coffee per day. I tend to sip on that cup all morning long. I like to bring it around the house with me, often settling in one area for long periods (like to do a craft or do computer).

    I chose the Ember mug and here's why not the others:

    1) The warmer- I couldn't bring the mug around the house with me, it had to always stay on the warmer. Also, as I drank the coffee down, it got hotter and hotter (less to heat). I had to keep turning the warmer down. Twice I forgot I left the warmer on and left the house and it stayed on all day. The warmer was also very hard to clean if you got a ring on it because it gets baked on. Literally I could not get the ring stain off. Lastly, the coffee tastes super gross after a few hours. Not sure why...but the heat from the bottom does something to it.

    2) Nextmug - I didn't like the shape of the mug. It looks deep but actually half of the mug is the heating element so it's not deep. Mine kept shutting off randomly, like within 10 mins of setting it, maybe it was defective? It also seemed to get hotter as the liquid became less like the warmer did.

    3) Ember - immediately I could see the temp on the app as soon as the liquid hit the cup, which I thought was NEAT! It turns its self on automatically when the coffee is put in it and goes to the last setting you set it at. It keeps it at that exact temperature regardless of how much is left in the cup (yay!). Thus it never overheats the coffee and the coffee stays delicious. I can take it all around the house and it is sturdy, looks cool and is nice and deep. It does shut off a lot sooner (from inactivity) than others, BUT it heats back up again surprisingly quick, so I'll take it.

    Others have voiced connectivity issues. I have an iphone14 pro and it hasn't had any trouble yet, but I just got it.

    For the record I was hoping I could control it via the app even when I wasn't home (like turn it on and off remotely) but it doesn't work that way. Since it's bluetooth and not wifi controlled you have to be near it for it to work.

    Good luck friends!

    Reviewed in the United States on November 7, 2024
    In the beginning, you will receive your mug in beautiful packaging and it will work as you wish.

    The empty mug weight is 414g which is a little heavy but the handle is very comfortable. The first setup use very easy just charge your mug and download the app to set your preferred temperature.

    Once you set the temperature you need 10+ Min on average to reach your preferred temperature, the mug works on 110/220v if you need to travel. Please take a couple of minutes to read the user manual to avoid any short circuit while you charge the mug.

    PROS:
    1- Great build quality, just don't use a metal spoon to avoid scratches.
    2- The average time depending on the temperature is 70 Min which is doing what is supposed to be done, and the actual temperature of the drink is similar to what is displayed on the app.
    3- Smooth app to control and easy to connect, and the mug will automatically off if the mug is empty.

    CONS:
    1- The charging time is very long more than two hours to get fully charged, this is very annoying!!
    2- The battery percentage decreases rapidly after a full charge until it reaches 3%, where it remains for a long time. I believe a software update is needed.
    3- I would like to see a 70 C degree nether than 62.5 to drink a black tea.
