This mug really works—keeps the coffee nicely warm (or hot, if you want that) for quite a while. We liked this mug so much that we bought two larger versions from the same manufacturer. It’s great! It seems very sturdy, cleans easily enough (but not in a dishwasher). When depleted of battery power, recharge requires a good bit of time, perhaps a couple of hours. You control the temperature with a simple button, no need to find your phone to operate an app. One thing to note—the handle is pretty rudimentary and not enormously comfortable. It’s OK, but not the large smooth coffee cup handle that you want to keep in your hand while curled up on the couch. But it’s OK. Overall, we love this purchase. These will be Christmas gifts for friends and family this year.

*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!

I've wanted one for a long time, finally pulled the trigger while it was on sale and it's a game changer as a new father. I'll make a coffee, baby wakes up, I forget about the coffee I'll make a coffee, go to change a diaper, I forget about the coffee I'll make a coffee, wife will call me for something, I forget about the coffee The best part about the cup is it's functionality and how I come back to my coffee and it's no longer cold no matter how many times I get distracted and forget.

The original review was accurate, but now that I've had the mug for 6 months (Originally 3 star), I have to reduce its rating... The mug itself is great, works well, and does what it says. It keeps my drinks at the temperature I set it to. The reason I'm reducing the rating here for 2 reasons. 1) Trying to reach an actual person or something more intelligent than an automated help desk, is seeming to be nearly impossible. - To expand on this: I have been unable to find any contact information to report any issues I do have with the mug or software (I have no issues with the mug so far, but the software annoys me to no end). 2) The software for the mug is so far below par, that they might as well just have a digital display on the side to show the temp and just set it that way. - Let me expand on this: a) If you don't keep your mug paired, ie: carry it with you 100% of the time, anytime it isn't paired, it forgets its pairing, and you have to go through the pairing procedure again to reconnect it. My car is a 2014, and the BlueTooth in it remembers my phone when I start it up, but this mug cannot. b) There's no way to override the heating to ON, if the sensor doesn't trigger to say the mug isn't empty, it won't turn on, even in the software Bluetooth connection. Through some digging, it states that it determines if it's empty by the significant difference in temperature: The mug is cold, pour warm to hot fluid in it, and it detects the temp change and determines it's not empty. I understand this is probably a safety feature to prevent the mug from burning out, but there should be some way to turn it on when you put room temp liquid into a room temp mug. (I usually make a batch of tea, and if I don't finish it all in a day, I use it the next day, I shouldn't have to microwave the first cup just to get it hot enough for the mug to realize it's full.) So in summary: -The mug is absolutely great, so far it's held up fine, with no chips/scratches. Works great to keep temp set. -Software needs a LOT of work. The biggest issue is the Bluetooth connection/protocol. I shouldn't have to re-pair it every day just to connect to the mug to change it from Tea to coffee, or some other temp for a different drink. -Better contact forms, for when you can't resolve the problem via automated help. I'm hoping that by rating this at only 1 star, maybe I'll get a way to contact the company, or at least they'll read this review and take the issues under advisement. Maybe even make a suggestions/complaints form to get these issues noticed so they know what to work on. Until I see a way to contact a live person, even if it's just email, or something simple, I cannot rate this higher than a 1. IF I were having a real issue with this mug (like it not working) I'd be out the money it cost me to buy it. Original Review Below this line: *********************************** Keeps my tea at the temperature I set, making every sip enjoyable. Pros: Heats relatively fast Keeps Temp very well. Con's: It's for Right Handers, if you're left-handed, (or hold the mug in your left hand), the LED is on the back side where you can't see it (less of a problem while you're actually holding it), but if you set it down for grabbing with your left hand you can't see the LED. The software is a little glitchy. I tried setting it to Celsius for a little bit, then when I tried to switch it back to Fahrenheit, it wouldn't switch, I had to reset the app completely to default to get it back to Fahrenheit. Couldn't find a contact form for issues (like the above software glitch), or suggestions.

The mug works great; I do wish the maximum temp was about 4-5 degrees higher, but we are a little intense with coffee. Also, the mug itself is insulated so even if the battery is not charged, it will keep your coffee warmer than a random glass mug will. And it won't burn your hands in the process. Mostly I am giving the 5 stars though because they have a WONDERFUL product support team. Responsive, friendly, and generous.
