Worth every penny if you enjoy hot coffee from the first sip to the last
Color: White Size: 14 Ounces
I was hesitant to spend this much on a coffee mug, but after using the Ember Mug 2 for several weeks, I can honestly say it’s one of those products that’s hard to live without once you’ve experienced it. The biggest advantage is that it doesn’t just keep your coffee “warm”—it keeps it at the exact temperature you prefer. Instead of taking a few sips, getting distracted, and coming back to lukewarm coffee, every sip tastes just as good as the first. That alone has completely changed my morning routine. The app is intuitive and easy to use. Pairing the mug took only a minute, and I love being able to set my preferred drinking temperature, create presets for different beverages, and receive a notification when my drink is ready. Once you have your favorite temperature dialed in, you rarely have to think about it again. The 14-ounce size is perfect for a generous cup of coffee or tea, and the 80-minute battery life is more than enough for my morning routine. When I’m working at my desk, I simply leave the mug on the included charging coaster, and it keeps my drink at the perfect temperature for as long as I need. It completely eliminates the need to microwave coffee halfway through the morning. I also appreciate how premium the mug feels. It has a clean, modern design that looks beautiful on my desk or kitchen counter, and the white finish gives it a sleek, minimalist appearance. Despite all of the technology packed inside, it still feels like drinking from a high-quality ceramic mug rather than a gadget. The mug is incredibly smart without being complicated. It automatically wakes up when it senses liquid, goes to sleep when it’s empty, and quietly does its job without requiring constant attention. Everything feels thoughtfully designed. If I had one piece of advice for prospective buyers, it’s to think of the Ember as a temperature-maintaining mug rather than a mug that quickly heats cold coffee. Pour your beverage in while it’s already hot, and the Ember keeps it at your ideal drinking temperature throughout your entire coffee break. That’s exactly what it’s designed to do, and it does it exceptionally well. Yes, it’s an investment, but if you’re someone who regularly reheats coffee, works at a desk, gets interrupted during the morning, or simply appreciates enjoying your beverage at the perfect temperature, it’s absolutely worth it. It has become one of my favorite everyday purchases and one that I use every single day. ... show more

Ember vs Nextmug vs warmer *update*
Color: Gray Size: 14 Ounces

*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! ... show more

Worth it but too tiny
Color: White Size: 10 Ounces
This product is quite impressive. While on the charger it will keep your beverage HOT all day. Off of the charger it keeps it HOT for 1 hr. While on the charger, it will heat up your beverage to HOT rather quickly. While off of the charger it takes way too long to do so. The product itself is amazing and I really recommend it for everyone who takes their time drinking and enjoying tea or coffee. I got this for my wife for Christmas because she constantly has to microwave her coffee because we have 5 children … but mainly because the 19 month old is demanding lol. I just regret getting a 10oz. I didn’t realize how tiny 10oz is because I assumed most mugs are 8oz. Wrong! lol. I am exchanging this for the 14oz. With the 10oz, once you put the coffee there’s hardly room for creamer and sugar (when it comes to a real coffee drinker). I gave it 5 stars because the product works excellently. The app is very impressive and fun (to me). I love to watch on the app how the T° of the coffee goes down immediately after pouring in creamer. I love it. You can customize the color code of the light on the mug and name the mug in the app. You can also set the T° you want your beverage to be going forward (set it and forget it). It’s awesome. I watched a YouTube video about the mug and the review said they don’t think it’s worth the $ although the product worked really well. That’s kind of an oxymoron. I think you’re getting what you pay for and in a good way. Your beverage literally stays HOT or (if you want) warm until the very last drop. I don’t often drink coffee or even tea, but when I do it’s Dos Equis lol jk… when’s I do I can’t stand where the last few sips are cold. I want to get one for myself except I hardly drink tea or coffee, just to show you how great the product is. I think the 10oz is too tiny. 10oz might not be as necessary to be in the size of a tech mug since it’s not much to begin with and can be finished rather quickly (although my wife still appreciates it in her lifestyle). For the real tea and coffee drinkers out there I highly recommend this product, but the largest versions. ... show more

Great mug, a LOT expensive, but definately works.
Color: Black Size: 14 Ounces
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. ... show more

Morning Coffee Must-Have
Color: Black Size: 14 Ounces
Review Image by Tina Balta
Seriously can’t live without my Ember Mug! I love my coffee HOT, but I also like to drink it slowly, so this is perfect for me. I’ve been using Ember mugs for years, and they normally last me a couple of years before needing to be replaced—but still worth every penny! My only wish is that the battery lasted longer. I’m actually considering getting two, so when one battery dies, I can switch to the other. I always hand wash mine and make sure it’s completely dry before charging. Definitely a must-have for me! ... show more

Best.
Had an Ember previously before they put ceramic lining inside. Loved it but bottom flaked off because of spoon. Purchased another brand and was very disappointed. Went back to Ember because of ceramic lining. Pricey but worth it. Highly recommend.

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. ... show more
