    This mug is perfect for people who like to take their time and enjoy their coffee, but hate Luke warm/cold coffee. This is especially nice to have for long periods of studying. I would recommend the larger size though, and think it would be well worth the price ( 10 oz just isn't enough in one sitting). Also, the off base battery life is shorter than expected, but sufficient. The app is super easy.

    The best part of my mornings is a hot coffee. I used to end up drinking it cold because I have two little ones to take care of. Not anymore! My ember mug keeps my coffee at the perfect temperature until I am able to drink it! It’s easy to clean, charges quickly, and holds its charge very well. It also heats up my coffee quickly if I pour it in cold.

    As someone who takes their hot beverages seriously, I was intrigued by the concept of the Ember Temperature Control Smart Mug. After using it for a few weeks, I am thoroughly impressed and excited to share my experience.

The build quality is top-notch, with a durable ceramic coating that feels premium to the touch. Revolutionary Temperature Control: The standout feature, undoubtedly, is the temperature control. The ability to set my preferred drinking temperature through the Ember app is a game-changer. No more burnt tongue or lukewarm coffee halfway through my work. The mug keeps my drink consistently at the perfect temperature. Battery Life and Charging Coaster: The battery life is impressive. It lasts long enough for me to enjoy my drink without rushing. The charging coaster is a smart addition, ensuring the mug is always ready for use without any hassle. Enhanced Drinking Experience: The Ember Mug has transformed my morning coffee ritual. Each sip is perfect, from the first to the last. It's not just a mug; it's an experience enhancer for anyone who appreciates the finer details in life. Conclusion: In conclusion, the Ember Temperature Control Smart Mug is a must-have for anyone who values the perfect sip of their hot beverage. It's an investment in your daily comfort and enjoyment, and I can't recommend it enough.

    Girlfriend has been using it every day since I purchased this for her birthday. She never finished her coffee since it got cold during her morning routine. Now this keeps her coffee warm and she can stop wasting coffee. Easy to set up with the app. Have washed it multiple times by now and still no issues with it charging or working.

    So it works fine without the app, but the app is required to increase the temperature. The reason i returned it is because the battery only lasts an hour or so. Unless you're able to set it on the charger in between sips, it doesnt stay hot long enough in my opinion. Its probably ok at an office desk, but just isn’t practical for couch drinking. Plus, you obviously can't microwave it so we inevitably end up transferring the drink to a different cup when the nattery dies.

    I never knew how much I could love a mug

    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 received this mug as a gift. The mug is 10oz which is too small for me and makes me choose a smaller size on my keurig if i want to add creamer. The mug dies very quickly unless you leave it on the charger. It doesn't usually even last for 1 cup of coffee for me. The heating causes my coffee (with cream) to build up a gross film on the sides of the mug

    Love the mug as it keeps my coffee hot. As with the other reviews, the inner coating was flaking off my old mug but that was due to using a teaspoon in it which the instructions advised NOT to... Per the user's guide: "For best results, we recommend using a wooden or silicone spoon to stir as a metal spoon can damage the Ember's coating"). Don't let that discourage you from buying one, just don't use a metal spoon in it and it will last a long time.

    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.

    Multiple benefits and conveniences - pricy

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    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.

    I love HOT coffee through the last cup and this makes that happen, does not "cook" the coffee and app gives me ability to adjust. Handle is perfect, and rim is not thick so that is perfect too........only thing is that is hold a cup size not a mug size of quantity, but for my expresso maker its perfect.

    This cup is great when it comes to keeping your coffee or tea at the correct temperature but two things need fixing. First, the battery life is not very good. They say they improved the battery life so I'd hate to think how bad it was before the improvement. Second, It's way too expensive. I bought it during a sale with $20 off plus I had a $15 reward coupon but I still ended up paying $65 for it and I still consider this to be too expensive for a 10oz cup regardless of how hot it keeps my coffee.

    The Ember keeps my coffee warm for at least an hour, which is the longest I have taken to drink a cup. Probably will last longer. However, 10 oz probably means up to the brim, and you wouldn't be able to drink it without spilling. But for 8 oz, it's great.

    The mug does maintain the temperature of 145 degrees, once it is set up. Some may prefer their coffee hotter, I'm OK with this temp. For me the app is useless for a couple of reasons. Most important and annoying is, mug loses contact with app(on phone) and the app will not complete the update it insists is available. Loss of contact with the app has no effect on maintaining the temp. Lastly, the inside of the mug stains quickly. To me it's just a coffee mug, so I don't care. The ladies may feel differently. All said and done, it does do what it claims,,,,,, it keeps your coffee hot, for about 75 - 80 minutes. I would buy it again.

    i bought this for my sister for christmas and she loves it. shes a big time coffee drinker (as am i, though im more of an iced coffee drinker and rarely drink hot coffee) and she prefers hot coffee, so i thought this would be perfect for her. once she opened it she was so happy because she had apparently been wanting one! this mug does so much, it allows you to choose your desired temperature and itll keep your beverage at that temp. you can use the included coaster to keep it charged/operating or use the internal battery in the mug itself. there is also an app you can download to fully customize and control every option with, which i recommend for all users of this mug because the level of control and customization with the app is great! but the app isnt needed to operate and use this, and you can still choose your temperature and stuff without the app! if you're unsure of what gift to buy someone and they are a coffee or tea drinker, definitely buy them this! they will love it!!

    This is my second Ember, which I bought to supplement the one I have. On the days I want two cups of coffee, sometimes I don't want to wait for one recharge before I start my second cup. On the charging pad, it will keep coffee warm all day, but off the pad, the limit is about 90 minutes. The thing I like best is that I get to set the temperature I want through the Ember app.
