Ember Temperature Control Smart Mug, 12 oz, Black, 2-hr Battery Life - App Controlled Heated Coffee Travel Mug

Of course this Ember mug is punitively expensive, but as luxury, technological products go, this is the business! It arrives beautifully packaged - as if an Apple product. The mug connects wirelessly to a sleek ‘saucer’ which connects to the power. The internal battery keeps all manner of hot drinks piping hot - at a temperature of your choosing - for at least two hours. The scrolling display is beautifully integrated in the sleek exterior. I love its look and feel and only quibble about the modest 350ml capacity. Hand-washing only, obviously but this product is a triumph of technology over a very mundane issue: cold coffee!

Mug worked fine on the charger but the battery would not charge and it was blank when lifted it off - I had chucked out the box. I have started an amazon return and boxed it up and will get back to you all to see if the defective good was properly refunded. They had no black mugs left so have ordered from another website as I really wanted one and the idea is sound if the mug works.

Really good cup to keep hot drinks hot for almost half of the day

I bought this on the recommendation of a friend who knows I like my coffee! The concept is a great idea albeit an expensive one. I should have known that all wasn't well when I could not get the mug to charge, but 2 factory resets later all was well until yesterday morning when it stopped working altogether. I tried another hard reset and then another - no joy. Checked the charger, changed the plug nothing. Ember offered to replace if I sent numerous videos but told me I would have to wait another month, understandable until I looked on the Amazon site and saw that I could have one supplied by Ember the next day. This left a bitter taste in my mouth! The idea is good but the design could have been better. I particularly disliked the mouth piece which you have to push down to use which means that you can get burned if you are not careful. Not sure that I shall be spending my refund money on a replacement

The good: sleek beautiful design, super simple control & operation. Keep s temperature well for about 90 minutes. The bad: about 100 ml too little volume for me but might be sufficient if you choose small or medium size coffee normally. Obviously would like a little longer retention but understand that impossible with size issues. Beautiful well designed product, will buy again & again & again.......

Battery’s life is about 1 hour especially if it’s heating up away from the base! But hey I have a black one and my wife a white one and is the first Thing we turn to in the morning since, I bought them!

Great product, but the lid broke after 5 months and the distributor has gone bust. Owner left the country. Not happy and amazon not interested in a refund. Buyer beware

Very stylish product. Charges quickly and keeps my coffee at desired temp for couple of hours. Only negative is it does not hold as much liquid as you would think.

Funciona excelente. Mantiene mi café en el punto perfecto hasta por dos horas con la batería, o indefinidamente estando en su base de carga. Es bastante caro, por lo que es un juguete para los que les gusta la tecnología.

Important pour moi de boire mon café très chaud

Come idea è molto bella. La pecca è la batteria, ci mette molto a ricaricarsi ed è in grado di scaricarsi completamente nel giro di 10/20 minuti.

Veio com problema de bateria, nao carrega.

So I felt like a review was warranted, because this little mug seems to have quite a lot of mixed reviews. I think that's because people buy it expecting it to do something that it wasn't designed to do. It all depends on your need. If you need a mug to hold a hot temperature, without electricity, for hours, this isn't the mug for you. And there is no such mug, aside from vacuum sealed options - in which case, those are better for that purpose than this one is. I like my coffee at 140. This mug will hold it there for about an hour on battery-alone. BUT, I rarely ask it to do that. PRIMARY USE: I wanted a way to keep coffee at a perfect temp, sitting next to me while I type reports, or visit with a patient in my office. I drink coffee (sometimes tea) throughout the day. It was far too often I was running to the microwave to heat up a cup - not ideal. With the Ember, I can have my mug sitting next to my computer at home, next to my computer at the office, or next to my therapy chair at the office... yes this means buying more than one docking station. But, come on - this whole product is a very 1st-world problem solver, anyhow. SECONDARY USE: I'm also a part-time law student, and I visit the law school in Minnesota once or twice each semester for intensive residencies. I get there at around 7am and stay till around 5pm. How can I get coffee? Starbucks is too far to walk. The student center coffee is unacceptable. I needed a solution to brew my own coffee, at my desk. My solution is the combination of this mug (to provide hot water at the perfect temperature) and the Handpresso Auto, which heats its own water, and brews an espresso shot directly into my already perfectly temperature Ember mug... The result? A lovely Americano, brewed at my desk using tap water and an Illy espresso pod. For this method, I do need to wait about 15 to 20 minutes for the water to be heated up to 140 (depending on how hot the water was when I first put it into the Ember). ACCURACY: So far, for me, it's been very accurate. I have tested it at different times with a laser thermometer, and it's almost spot on each time. CONSTRUCTION: I like the soft touch materials, even on the charging dock. The standard lid is plastic, but works very well. The 360-degree drinking design is nicely thought out. The "dial" feels a bit scratchy - not smooth. Which surprised me, given the great attention to detail in every other aspect of the design (including the lovely packaging - similar to Apple Products packaging). CHARGING: One con that doesn't make much sense to me, is that the battery isn't being recharged, while the mug is on the doc being kept warm. This makes little sense, given that there is enough electricity being input, that both could be happening at the same time: the mug could be heating/maintaining, while the battery is being topped off. Perhaps there is some technical reason this isn't happening. But I can't fathom one. Most people wouldn't be ok with their laptop or phone being un-charchable while it was in use. But, does that change it from 5 stars? No. APP: Kinda neat. I'm a tech nerd, so it's cool, but not really necessary. Would be nice to see a computer app for this - maybe something that could pop up in the notification center of your iMac... sometimes I'm working on the computer and have no idea where my phone is even located. OPTIONAL RING: Embarrassed to say that I did get this LOL. I like the plastic lid, because if I'm traveling or walking around, the spring-loaded lid keeps the splashing at bay, and bug/gnats from sneaking into the coffee (I sometimes do sessions outside). But generally, I prefer the ceramic feel, and was happy to see that as an option - it, too, came in lovely packaging. Hopes for the Future: I'd like to see a car lighter option with a docking station designed to fit into a standard cup holder (about the size of the bottom of the Ember). I have thought about mounting an extra dock in my car, but I think it'd be too difficult. But eventually, it would make sense that Ember could at least increase their sales by 1/3 or even 2/3's if they re-marketed this add-on to EXISTING customers. One huge part of expansion is being able to market a product to your existing customer base (like with the ceramic ring). An auto-version of the base would most certainly be more successful than the ceramic ring. I'd like to see the battery start charging at ANY time the Ember is on the dock - not just while it's powered off. I'd like to see the display modernized. The dot-letters and dot-images remind me of dot matrix printers for some reason. Not the most aesthetically appealing, but not horrible either. Would be nice to turn off the display while on the dock - I don't always want to see what the battery level is - or show off to others my dot-matrix-y display LOL.
