Customer Ratings & Reviews

This mug itself has been fantastic. A self-heating coffee cup, the future is here! The app and bluetooth connection can be a bit fiddly but when it works its a dream. After having this mug for under a year and a half having exclusively hand washed it, the inside of the mug is flaking off. Just a few months out of warranty and it's unusable in this state unless I would want to inevitably drink whatever material it's coated with. I've reached out to their support team and am waiting to hear back but in any case I would encourage researching the coating flaking issue online if you're considering anything from this line.

What a huge disappointment!! I like my coffee hot so I’ve been very careful with making sure the base is charged. What I didn’t plan for is the interior paint/coating to be chipping off ~ I’ve never put it in a dishwasher or used anything metal for stirring my coffee so I’m perplexed as to why this is happening. Tried customer service at Ember multiple times..no connection ~ no response!! For the cost of this mug there should be better customer service! What a BIG DISAPPOINTMENT!!

One of the spring loaded pins in the coaster has had it's spring fail, causing it stay recessed & not make contact with the mug. Really disappointed with the timing of this failure, 3 days after warranty expiration. $40 for a new coaster. My wife does love it for her tea.

The mug’s quality and heating system is exceptional

not a fan. $100 for a mug that is not dishwashable, cost 20x more than a $5 one, and make it feel like you basically only have 1 mug you want to use... just so that your coffee stays warm for like 30 minutes longer. you can even get a heated coaster for like 1/4th of the price on amazon, and it would work with ANY mug instead of only one, which you have to repeatedly handwash.

I love the mug and it’s the perfect solution for me. It’s just the charging coaster that keeps failing since the two little pins get stuck. Ember has replaced it twice but I worry what will happen in 2 months when the mug is out of warranty.

It caught fire after 8 months and the manufacturer said I put it in the microwave without replacing it unde warranty

I had been wanting one of these mugs for quite some time. Couldn’t justify the full price but finally bought one on sale. I’m definitely a bleeding edge technology person so the technology was very appealing. Ideally, technology should make your life better and easier, not more complicated. Unfortunately, the Ember mug had a few short comings that ultimately made me return it. I felt the quality was certainly there, but the functionality wasn’t better enough to replace my yeti mug. Here are a few things that the Ember fell short fir me. Hopefully the makers will consider these in their next generation of mugs. 1. The mug was too small. Most of the people interested in this mug will be heavy coffee drinkers and will probably drink more than the small amount this cup offers. By the time you drink the coffee out of the small size, you really don’t even need to keep it heated. No doubt, although the Ember would beat out a readitional non insulated mug, however the yeti cups (with closable lid) keeps beverages hot just as long as the Ember and better. I say better because with a heating element in place, as you get diwn to the final quarter cup, the coffee becomes visibly “cooked” and tarnishes the taste. Especially eith creamer. That doesn’t happen on a yetti. 2. The battery doesnt last long enough. Since the embrr is small, most people are going to have two maybe even 3 cups of coffee with it. The battery last for the first cup, but runs out of juice the second cup or third cup. I understand you can put it on the charging stand, but that’s not always possible when you have a lot of meetings to go to or stopping into other peoples offices to chat . Again, the Yetti (with a lid) wins out. 3. convenience - the embers app is very well-made, but it’s an extra step and after a while gets tiresome to go to. Not a big deal as you dont have to use it after its set up. 4. Longevity -the Ember is probably good for 2 to 3 years. After that the battery should be toast or brgin to diminish. I don’t think there’s a way to replace the battery. I’ve had yeti cups for 10 years and still going strong. 5. Simplicity. The ember is not dishwasher safe. The yetis definitely win out here. 6. Cost - Even on sale, I can buy two or three yetis for the price of one Ember. 7. The Amber doesn’t come with a lid. The yetis do. 8. The yetis work far better in a car. Sumnary: even though I’m both a coffee snob and bleeding edge technology enthusiast, the Ember ultimately became an inconvenience to use compared to a simple yeti cup. Even if the prices were the same between the two, I think I would go with the yeti just for the ultimate convenience and similar performance of keeping beverages hot. Just my two cents.

I love my Ember mug. Is it expensive? Absolutely. Is it for everyone? Absolutely not. The app for iPhone is hit or miss, but allows you to set the colored light on the bottom as well as temperature preference. It tops out at 145 degrees which is plenty hot for me, I actually dialed it back to 140. This mug has mediocre battery life which is offset by a few factors, specifically sleep mode and the charging coaster. First, the mug can detect liquid inside and will not heat if it is empty, saving battery and allowing you a few cups full before having to charge up. For charging, the included coaster charges up quickly and allows you to keep your drink warm effectively indefinitely, which would be ideal for office workers and other more stationary tasks. It charges up quickly, I only wish the coaster connected via USB instead of a proprietary connection. The mug is IP67 and very easy to clean by hand and warm water. Just be sure to fully dry off the rings on the bottom before charging.

Purchased as a Christmas present for the wife! She loves it and might get one for myself now. She says that her coffee now stays at the perfect hot tempo for her no matter how long she takes to drink it. Makes her coffee more enjoyable in the morning.

First, almost certainly your question, like mine was before I got my Ember, is can a mug really be worth the cost? Don't they make warming coasters for around $20 that will do the same thing? After using my Ember for 3 weeks is, without hesitation, yes it is worth the cost, and no, a mug warmer is nowhere near a replacement for what Ember can do. I drink between 5 and 10 cups of tea a day, and I got used to the phenomenon that I could drink it when it was scalding hot or I could drink it lukewarm, but I had about a 60-second window of that perfect sip of tea. I'm very precise with my food and drink (for example, I time my tea steeping for exactly 1 minute and 20 seconds and exactly 6 mL of lemon juice per cup), so having a tea mug that can get my tea to exactly the perfect temperature for every single sip, no matter how long it takes me to drink my tea (137 F, in case you're interested)? That sounded too good to be true. And yet, it is that perfect. It took a little tweaking at the beginning using the Ember app (Ember actually encourages you to tweak it to perfection; they give suggested temperatures, but they want you to find your exact sweet spot), but then it is zero maintenance after that. Whenever I pour tea into the mug, it can sense that there is fluid in the cup, and it begins the processes of allowing the tea to cool down to the right temperature and then maintaining that temperature until the very last drop. And, I really mean it, the very last drop (as a small note, the last drop is slightly hotter than the rest of the drink because it's been sitting on the heating element longest, but frankly, that's a joy to get a small burst in temperature rather than having the last sip be tepid as I've been used to). I even get an alert on my phone and Apple Watch letting me know that the mug has reached the correct temperature so I can start drinking it at exactly the temperature I wanted. Also, the mug works, for a while, off of the coaster. I keep my coaster on my desk, but I can get about 2 cups of tea between charges (depending on how fast I drink it), so I can have that same temperature expectations when I'm away from my desk. I wish the battery was a bit more substantial (2 hours would have been somewhat ideal) or if there was perhaps a portable charging station that holds a longer charge. Or, I wish an additional coaster was a bit less costly so I could have them at multiple points in my house for more convenient charging. But, now we're just getting into wishlist territory, and none of those are a reasons to knock the product down in rating. There is one design flaw that I think is somewhat problematic, and based on some other reviews, I'm a bit concerned that it will end up shortening the life of the charging coaster. The mug itself is water resistant, which is helpful for a product whose sole purpose is to contain water (it is not water resistant enough to let it run through the dishwasher, but hand washing a mug that I use many times a day is not a problem). However, if water gets on the sides of the mug, it naturally goes down the side, down the curve of the bottom, and into the seam at the rubber ring at the bottom. This is fine, except the charging coaster is not supposed to get any moisture in it at all. I usually wipe the bottom of the mug with a paper towel, touch it to feel if there is any moisture, and still about 30% of the time, when I pick the mug up from the coaster, there is a ring of moisture on the coaster itself. Because using the coaster while drinking from the mug is how you can use it somewhat indefinitely, it's not an option to just leave the mug off the coaster. I have read reviews stating that the charging nodes on the coaster get corroded because of the moisture, and I can see how even the most careful user could run into this issue. Other things I don't love about it: the handle is a bit uncomfortable because it has somewhat sharp edges, and the lip of the mug takes some getting used to for the same reason. They kept the mug walls very thin (it is actually stainless steel coated with ceramic, presumably to both control the temperature through the entire mug more efficiently and to keep the weight of the mug down as it's somewhat heavy because of the electronics stored in the bottom), which is fine, except it lends to sharper edges. I got used to both of those things pretty quickly and haven't thought about it for the last couple of weeks. However, as far as design goes, it's a very attractive mug, and remarkably, the sides are always cool to the touch, even immediately after pouring boiling water into it, so it is clearly an exceptionally designed mug. I could go on and on about it, but the bottom line is that this is, no doubt, a luxury. It feels really hard to justify paying $100+ for a mug. And yet, it has completely transformed how I drink my tea, and every bit for the better. And, aside from a one important design flaw, rarely do I see such perfect implementation of technology. Well done, Ember.

I never realized how much the coffee drinking experience could have been improved with this cup. To pour a cup and get lost in work only to return and find the beverage the same perfect temperature (to the last sip) is heavenly. It literally puts a smile on my face every time. A start reduced for a a few reasons: - This color only comes in 10 ounces... I'd like to have it in a 12-ounce size. - The Android connectivity (or lack there of leaves a bit to be desired. Luckily once you set desired temperature in the mug you don't have to futz with it anymore. - The battery could be longer than 90 minutes. Sometimes I take a meeting away from the charger on my desk and the battery runs out... Then you really miss the experience

Great mug to keep my coffee hot! Got the stainless one because the plastic looking ones just looked cheap and they were almost the same price. The battery lasts about two hours. Normally, it won't take me that long, but I happen to leave the house one time and came back with my coffee still warm. The app said the battery was depleted and gave me the temperature. It was only off by a few degrees, so I figure two hours was about it. My cons with this: 1) the price. It's expensive for a mug. 2) At the time, this was the only size, 10oz. That's way too small. All my mugs are 12-16oz. This won't even hold a large brew on a Keurig. Huge negative. Now they have a 14oz one and, of course, you're going to pay for those few extra ounces.

I loved my Ember Smart Mug² so much that I bought another as a Christmas gift. The copper color is stunning, adding a touch of elegance. Like mine, it keeps drinks at the ideal temperature, controlled via a user-friendly app. It's a thoughtful gift that combines style and technology, perfect for anyone who loves their hot beverages. Highly recommend for a unique and practical present.

The conveniences and benefits come at the cost of one convenience, and it's that washing and caring for this mug is more of a hassle than for a regular/dishwasher safe mug. - it is also quite expensive. Though the cup can be safely submerged in water for the purposes of cleaning, water does seem to seep in between the rings and silicone base. Also, the stainless steel does stain very easily with turmeric-based teas and is very prone to scratching from cleaning pads, so be careful about that. I will give my personal wash/care routine at the end of this review for anyone interested. The reason why I still give this cup 5 stars is that it has two major benefits. The first is the obvious one, it keeps beverages nice and warm. I love that I never have to make trips to the microwave. I generally keep the mug on the charging coaster as this is necessary to keep beverages heated for longer than 30 or so minutes. However, the other major benefit, which I initially didn't anticipate, is that I never burn my tongue or expose myself to damagingly hot beverages when using this cup. It always let's me check and make sure that the tea I brewed in it has cooled to a safe and enjoyable temperature before I take that first sip. And then, it keeps it at that temperature! I will say that this cup is less effective at heating drinks up. This is because, unfortunately, it seems like the sensor in the cup gets confused when the temperature of liquids in the cup is equal to the temperature of the room. It thinks the cup is "empty" and stops heating the liquid up. It would be great if Ember could develop a "Heat" setting/function on the app, to let the cup know that there IS liquid in the cup and for it to keep heating past that room temperature confuse point. Now onto care/use guidelines: I usually only use this mug for straight teas and avoid putting milk or other additives that might burn or stain the bottom of the cup. I wash by shooting water up into the cup while holding it upside down to avoid getting the base wet. Then I wipe down with a microfiber cloth.

The Ember Electric Mug is a remarkable innovation for those who take their hot beverages seriously. This smart mug allows you to set and maintain your preferred drinking temperature, ensuring that your coffee, tea, or other hot drink is perfect from the first sip to the last. The build quality is excellent, with a sleek, modern design that fits well in both home and office environments. One of the standout features is the Ember's battery life, which is sufficient for a morning's worth of hot beverages. The charging coaster is a smart addition, keeping the mug powered throughout the day. The accompanying mobile app enhances the experience by allowing remote temperature control and customization. However, the price point might be a bit steep for some, and the mug requires regular cleaning to maintain its functionality. Also, its reliance on technology means it might not be as straightforward to use for those who prefer a simpler mug. Despite these minor drawbacks, the Ember Electric Mug is a luxurious, high-tech solution for anyone looking to keep their drinks at the perfect temperature.

I never thought I needed this in my life, but the Ember cup changed my life forever. There is no better feeling than taking a sip of your cup of joe 2+ hours later (as long as cup is charging on plate) and realizing it’s still at that perfect temperature you set it at. Even my boyfriend feel in love with it, so I got him one so we don’t have to fight over the Ember cup. The copper mug is a really nice color and it doesn’t look like a tacky. Only downside is that these metallic colors don’t come in a bigger size.

I received this cup for Mothers' Day. I must say it is one of the best gifts I've ever received. Usually I drink 2-3 cups of coffee a day. This sleek cup is perfect, because it is easy to use. You power the cup on by pressing the bottom of the cup. It recharges fast. It fits perfect on my nespresso maker. The app is easy to download and use on the iphone. The app is self-explanatory and does not require much input. I set my cup temperature at 140. I only wish I had the larger ember cup. I washed this cup in dishwater and it worked perfectly the next day.

The Ember Temperature Control Smart Mug has significantly upgraded my daily routine. I'm giving it four stars for its remarkable performance and innovative design. This mug's sleek and durable build, coupled with its intuitive app, made setup effortless. It keeps my beverages at the ideal temperature for extended periods, allowing me to savor every sip without rushing. The battery life is impressive, ensuring multiple hot drinks throughout the day, although a larger capacity would be appreciated for longer sessions. Overall, the Ember mug is a game-changer, delivering on its promise of a perfectly heated drink. Despite the minor capacity limitation, its performance and design make it a worthy addition for anyone seeking beverage perfection. Highly recommended!
