   Controlling the temperature is amazing. Beautiful mug.

   I love the mug but the advertised 10 oz means filled to the very top. I use it for 8 oz. I also own the 14 oz mug but only fill it to 12 oz at most. I wish the battery lasted longer for a single cup of coffee off the charger but leaving the mug on the charger works great.

   Bought for my husband for Christmas and he loves it. The mug is big enough for a Nespresso latte. It stays warm for a few hours on a single charge, and if on the base of course it will stay warm much longer. I honestly balked at the price of this product but now that I've seen it in use, I think it's totally worth it and I told my husband I wanted one too!

   Daily Use for a Year — Still Love It

   I’ve been using the Ember Smart Mug 2 almost every day for about a year (I skip caffeine on Saturdays), and it’s easily one of my favorite purchases. I haven’t had a single issue with it during that time.
   
   What I like:
   
   Keeps my coffee at an exact, consistent temperature once set
   
   The app lets you dial in your preferred temperature, and the mug remembers it afterward
   
   Build quality feels premium, and the copper finish looks great on my desk
   
   Works especially well when paired with a sliding lid to extend battery life
   
   With the lid, I rarely need to use the charging coaster while drinking
   
   What could be better:
   
   The app can be a bit annoying to use, especially during initial setup
   
   Battery life is short without a lid, so slow sippers will want the charging plate within reach
   
   Once everything is set up, the app becomes mostly hands-off, and the mug just does its job. If you like your coffee or tea at a precise temperature and tend to sip slowly, this mug—especially with a lid—has been a daily essential for me.

   *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!
