This has been a game changer for keeping coffee or tea at the exact drinking temperature without constantly reheating it. The app control is easy to use for setting preferences, and the mug maintains a steady temperature so every sip stays just right instead of going cold. The build feels premium and solid, and it has held up well with regular daily use. Battery life is usually enough for a full morning session, especially when kept on the charging coaster. What I also appreciate is how useful the travel version is for being on the go, keeping drinks warm during commutes or longer outings. Overall, it’s a high-quality, thoughtfully designed product that consistently delivers on its promise and makes everyday routines a little better.

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.

The one thing that I wish this mug had is a indicator light on both sides. I sit the cup on the left of my keyboard. This puts the indicator light where I can't see it. Other than that, it keeps the coffee warm the whole time. Based on some reviews, I bought a lid for this mug. However, I don't think it is necessary. The mug comfortably holds 220 grams/ounces. That's about a third less of what I usually brew. So, there's less to drink and less time for the coffee to go cold. But, if you're outside or on the road traveling, this mug will keep your coffee warm and the lid will serve to mainly keep stuff out of it or prevent spillage.

I'm very excited about this mug. I had a white one for a year and a half, but kept it on the charger too much so it "died". The thing I like about the Stainless one is that it won't show the spoon marks on the bottom of the mug like the white one did. Plus the white one stained too. So I'm thrilled with this one!

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.

I bought two of the 14oz white Ember Mugs. The mugs are very reliable and work as advertised. However, there is a problem with the chargers. After using them for a few months one of the mugs stopped working. Turns out the charger charging “pins” had gotten depressed and was not making contact. No idea how that happened but my husband used a small tweezer and was able to pull it out so that it works. Every few weeks it happens again and he pulls the pin out again. But he said this last time the pin got depressed so deep that he did not think he could get a grip on it. He eventually managed it. So today the same thing has happened the other charger. This one is rarely used. I’m not happy. This is clearly a defect with these chargers. To make it worse I came to Amazon to just order a new charger and they no longer have white chargers. I gave these mugs a rave review on Amazon when I first got them, but I wanted to make potential buyers aware of this issue. I just read many reviews that mention this same issue so I am sure that Ember is aware of it. Mug are great, chargers can be defective. Obviously without the charger the mug does not work.

First, the Ember Smart Mug does exactly what it says it will do. So it would not be fair to give it less than 5 stars. If you set the temp on your app to 145, it will keep your drink at 145. It is easy to use. Once you have paired it to your phone initially, you never have to think about it again. Just hand wash it, put it on the charging coaster, and it will ready the next day. BUT DOES IT SOLVE THE COLD COFFEE PROBLEM? Ember is expensive. For that price, it should ensure I never have cold coffee again. Unfortunately, that is not entirely true. Ember will keep your coffee hot, but only until the battery runs out. For the 14 oz mug, this takes around 1.5 hours when fully charged. Like most coffee drinkers, you might down the first cup in 15 minutes, the second over the next 1/2 hour, but that last cup may sit on your desk for an hour or more while you're busy. Then when you get a moment to take a sip; ugh, cold disgusting coffee. So the WHOLE story is that Ember will keep the first and 2nd cups piping hot, provided you finish them within the 1.5 hour battery life. But honestly, I didn't search for a $120+ coffee cup for the first 2 cups of the day. I searched for a way to keep that 3rd cup hot, for an hour or more if possible. My first attempt to work around the short battery life was to use a standard coffee cup for the first 2 cups, and then use Ember for the 3rd. This did help, and the 3rd cup stayed hot longer. But not long enough for me. And should I really have to jump through extra hoops for a coffee cup that costs over $120?? I didn't think so and had made up my mind to return it. DON'T GIVE UP, THERE IS HOPE! Thankfully, before giving up and sending Ember back, I searched on Ember's website for ways to extend the battery life. And there I found the HOLY GRAIL... EMBER can heat your coffee while sitting on the "newly redesigned charging coaster", WITHOUT using your battery! WHY didn't I find this sooner! All I had to do was move the charging coaster to my desk, instead of next to the coffee pot. Clouds parted, stars aligned, and now my 3rd cup will stay hot all day if I want. And I don't notice any difference with the coaster on my desk. It is so slim and sleek, I don't even notice it sitting in that spot that was reserved for my coffee cup anyway. FINALLY, HOT COFFEE ALL DAY! I would give Ember 6 starts if I could, for finally solving the cold coffee dilemma. Thank you Ember for such an amazing product. Might be worth HIGHLIGHTING the ability to keep your cup hot for hours provided the charging coaster is used.

I ordered the Ember and read the reviews after ordering. I was a little hesitant after reading some of the negative stuff in reviews. I don't usually write reviews, but I like this product so much, I thought I'd give my input to help others out. -I work from a home office and found that my coffee tea gets cold before I finish it because I take my time while working. -It is even better than I expected to have drinks stay at the temperature I want. With the app, you can adjust the heat to the way you like it. The last sip is as good as the first. -I didn't have any trouble setting up the cup and app. I followed some guy's advice in the reviews to make sure the cup is fully charged before setting up the app and followed the instructions. That worked great for me. -I haven't had any of the issues some seem to have had with the Bluetooth disconnecting (I use and iPhone mini). It's been very solid. Twice in the first two weeks, it seemed to not be heating though it said it was connected. I simply turned off the heater through the app and turned it on again both times and it worked fine. -There's some talk about not getting the charging stand wet. I am careful with that, making sure that I haven't sloshed and gotten the bottom of the cup wet. Not a big deal at all to pay attention to that. I don't walk around with normal mugs wet on the bottom anyway. -One review I read complained about the length of time the mug holds a charge. I generally, sit it on the charger by my workstation, so it's always charging. If you do that, no problem with charge. A few times I've taken the mug other places in the house. It easily goes 1.5 hours and my guess is it'd approach ~2 hours, maybe a bit more. That's plenty long for me. And I can recharge it and use again later. It's definitely no iPhone in terms of battery life, but works for what I do. If you expect it to keep something warm for 8 hours, I don't think it'll do that. -It's a very solid-feeling mug that's got a really nice feel. Good heft, some sort of traction rubber on the bottom so it stays put where you set it down. -I was hesitant reading some of the negative reviews relative to the price. I am 100% happy with this purchase. One of the best things I've gotten recently and makes a fun difference in my days. Highly recommend it.
