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.

This is my third Ember mug. The first two were gifted to me. I am a coffee sipper not a gulper. I was constantly reheating my drink prior to receiving this gift. These mugs typically keep your drink warm for about 80 minutes before needing recharging. So this indulgence is perfect for me. My only complaint is that it only lasts about 2 years before the battery no longer holds the charge that long. I give it 5 stars for the first year then things start to go down hill after that. Maybe I am being unreasonable expecting something in this price range to last more than two years ?

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 Ember Mug 2, 14 oz Temperature Control Smart Mug is hands down one of my favorite purchases. I love the heaviness of the stainless steel, it feels substantial and high quality in your hands. Best of all, it keeps my coffee at the perfect temperature from the first sip to the last. No more reheating or rushing to finish before it gets cold. It makes my morning routine so much more enjoyable. LOVE IT!

Great coffee mug. Easy to clean. Me and my wife love the copper color. It is a little pricey for a coffee mug, but that everlasting warm coffee hits different in the winter

The first one the battery didn’t last long, this one we cover the coffee cup when we’re not drinking out of it which saves battery power it’s lasted quite a while
