Customer Ratings & Reviews

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.

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 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

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 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.

Price is a little steep but if u get it on sale its a great buy. Keeps the drink warm but i mostly have to use it on the charger unless i give it a full charge the night before. It gets a little annoying when u get the coffee film on the drink while keeping it warm but finding the right temp setting could help this

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.

Works as advertised. This is my favorite cup and I use it everyday. It keeps my drinks hot for most of the day. I would recommend it to everyone that likes hot drinks

Love that this keeps your beverage hot. The charge doesn’t last as long as I would like however it works well. If I was to buy again I would buy a larger 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.

I was given one of these a gift, and like it. My daughter expressed interest and since she has a birthday right after Xmas I thought I would get one for her. I'm not one to gulp down my coffee so I like that it keeps it warm for about 1 hour, without needing to be on the charging pad. Wish it were a little larger capacity. 10 oz seems skimpy. Battery life could be a bit longer. I wish it lasted 2 hours (I solve this by using the charging pad as a coaster) I've dropped this cup several times and it survives well. I think this should be about 1/2 the price

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.

The Ember Heating Cup is a high-quality product that provides a unique and enjoyable experience for tea and coffee lovers. Its sleek design and precise temperature control feature make it a must-have for those who value both style and functionality. While it is a bit pricey compared to regular cups, the Ember Heating Cup's exceptional performance and durability justify its cost.

We already owned two Ember Smart mugs that have seen their batteries deplete over the years. Total Tech had a good deal on these mugs. I think these are a steal at $50, that deal ends soon. The cup works well, keeps your drink hot, and the app is polished on both iOS and Android systems.

Great product and a great Christmas gift or any Coffee or tea drinker. I wouldn't want to give this up now that I am used to hot coffee!

This mug is perfect for me.... HOWEVER, it may be too small for some people. I like to take my time drinking my coffee as I watch the news in the morning. My kitchen is close by, so if I really wanted a second cup, it would be a one minute job!!! The mug is a tad heavier than a regular one, but the handle is perfect for comfort and the lip is thin and makes your coffee taste delicious. What do I like BEST about this mug??? The LAST DROP OF COFFEE IS STILL HOT!!! Ummmmmm.

This was a good product. Performed as described. Keeps my wife's coffee hot. The only drawback is that since the coffee stays warm, we can use a larger cup and not have to refill as often. We will be looking for a larger-size ember cup.

I love the active heating feature, but expect it to last a year before the battery experiences issues. The Bluetooth connection also isn't entirely reliable, unfortunately.

This works so well! I would recommend getting the larger size, as this is not the standard cup size. However, the charge lasts a long time and keeps the coffee so hot!

Like most of us these days, I am working from home and using coffee cups instead of travel mugs. Naturally, I am a slow drinker, and I hated that my coffee would always get cold before I could finish it. Then I found the ember 10 oz mug. I'll admit, the price is high, BUT, for me, it has ended up being well worth the price. Ever since buying this mug, I have finished my coffee and teas without any waste. For me, the less than desirable battery life doesn't bother me. Because I work from a desk, I am able to leave the cup on the charging pad which will keep my drinks the perfect temperature all day. If I don't have the mug on the charging pad, I am able to get over an hour of 140 degree coffee or tea. I liked this product so much that I ended up buying one for my mother as a gift and will likely buy the travel mug in the near future.
