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.

*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!

This review is based on Ember's customer service. The mug worked well for about six months. The pin on the charging coaster broke and I reached out to "customer service" multiple times to ask if it was covered under the 12 month warranty with only one response indicating they would respond promptly; I waited a couple days tried in vain to reach them again with no response. I ended up purchasing a new charging coaster, so that I'd not have to discard the mug and have it be a total loss. If or when it breaks again I plan to replace it with the Nextmug. I still have the broken charging coaster just in case Ember contacts me in the next week or two.

Just hot enough at max temp for me. Lasts long enough off the cradle to go through several cups of coffee without rushing. Cup is easy to hand clean, and enjoyable to use- the texture is just right. I’m very satisfied with this purchase for my caffeine addiction.

Bought this as a gift and she absolutely loves it. I'm glad I went with the larger cup because it's the size of an average coffee cup. She keeps the base at work and her coffee stays warm/hot. Very durable and easy to clean.

The first one I had was perfect. So much so that I couldn't even imagine having coffee with out it... Always at the perfect temp... I can set it down on my desk, go away for an hour or more and come back and it's still delicious...But... (pointing to my butt)...The charging plate is seriosuly flawed... there are 2 little pins that connect to the botton of the cup... The one pin gets stuck and stops making contact rendering the cup useless... Customer Service was TERIFFIC and replaced the charging plate, but I'm not sure if it will happen again and would they replace the plate again if it did. It must be a problem for them to have a whole page on their website about it.Hopefully they have that issue solved. As I said above, this mug is incredible... and coffee without it is just not the same anymore.

It works beautifully. Temple is automatically maintained. Got distracted with a chore? You coffee is nice and hot and waiting for you. We bought two more. We are cautious and really dry the bottom of the cup. Easy to maintain and attractive. Highly recommend.

I like to drink a long cup of coffee over 20 minutes or so, sipping every once in a while and that was always a rapidly declining enjoyment with normal coffee mugs. The colder the coffee got, the more I would wince when I drank it. Off to the microwave! Not idea.I got the Ember more as a tech gadget than anything because I was skeptical. However, this thing really works for what I need! I never really need it for more than 30 minutes so for me the battery life is absolutely fine. In those 30 minutes the coffee stays at the exact precise temperature I set and it's an enjoyable sip... almost until the last drop. I say that because as the coffee level gets low, the heat still stays at the same temperature which means your last few sips could taste burnt. I learned to turn it off when the level gets to a certain point and I'm able to finish the coffee still hot, but not at my "maximum enjoyable level".Still... I ended up buying a smaller one for home after using this one for work. Expensive and not really needed, but it's something that has brought enjoyment every single time I've used it. If that's what you're looking for, I recommend it!

Not really much to say here, yes these mugs are expensive, all I would say is keep watching the price, normal retail is £149, I have seen the 14oz grey version drop to as little as £99, kicking myself for not buying then, I took the plunge when saw back on offer at £119, the mug itself works flawlessly, I never turn it off manually and goes to sleep as soon as it’s empty and wakes up once a drink is poured into it.The app which I am using on iOS could be much better, it very rarely automatically connects to the mug, however this is not a issue as once you’ve set your desired temperature the mug will remember those settings and the white led will remain solid once that temperature has been reached.I find the mug very easy to wash, I am mainly using with Tassimo coffee so even after being left a couple of hours and there’s a ring round the top of the mug it cleans off very easily.I read previous reviews of folks complaining that the mug marks easily from spoons, so with that in mind I am using wooden tea spoons and can confirm no marks as yet.
