I received this mug as a gift, and it's perfect. I paired it with the app, which can be a little glitchy, but not a complete waste. You can control how hot you want you coffee, up to 145 degrees. Also, if you share your mug, or have the same color, you can customize the LED color to identify who the cups belongs to. You cannot microwave your cup, but honestly, I have poured in cold creamer and waited for my coffee to get hot just to experiment. It's neat. And if you pair the mug with the app, you can choose which temperature to maintain your coffee.I charge the cup after using it, and will simply take the cup with me to my home office for a few hours. Battery life away from the base depends on the maintained temperature.Overall, I love this mug, because it's not ... MoreI received this mug as a gift, and it's perfect.

You can also wash the mug, but not keep it submerged in water, I recommended immediately washing it, or if you don't have time, fill with regular water to soak, turn off the base, and clean it later. Again, just don't submerge it or it will ruin your cup. All this is in the nifty packaging it comes with!I would recommend as a gift, buying it for yourself or to impress your guests.

My experience with the Ember Mug was far from what I had hoped for, both in terms of product quality and customer service.Upon opening the package, the mug appeared to be in pristine condition, with no visible signs of damage. However, things took a turn when I used the mug for the first time. After a brief use, I placed the mug back on its charging base only to find that it had stopped working. The battery continued to drain, and upon closer inspection, I noticed that the gold contacts on the base were bent and shedding metal fragments. These damaged contacts not only rendered the mug useless but also caused scratches and tears on the rubber pad of the mug's bottom.I reached out to Ember's customer service, hoping for a resolution.

Currently, this is probably the best overall drink warmer on the market but it's just a matter of time before someone comes out with something better at a lower price point. Especially for the price, it doesn't last long enough without having to be completely replaced and has some annoying quirks. Some of the ways this product needs to be improved are:Ability to Force Warming of Cooled BeveragesCurrently, if the mug detects the liquid inside to be too cool, it will register the mug as empty and will not warm the beverage. A firmware update is needed so we can hit a button in the app to temporarily override this limitation.Larger Capacity Options14 oz is often too small, especially if we add creamer or anything to our beverages.Replaceable BatteryIt's ...

This practice needs to be made illegal since companies don't seem to want to act responsibly on their own.Qi Wireless ChargingUnless there is a legitimate reason to have to use the proprietary contact charger, switch to an industry-standard Qi wireless charging coaster. It makes no sense to use a contact charger for a product that is exposed to liquids. Being forced to use an inferior proprietary charger is annoying and irresponsible.
I've had this mug for 4 months now and it is great for brewed coffee and hot tea WHEN it decides to work. Trying to update firmware is impossible and always disconnects and stops trying to update at 50% even if the mug is at 100% and even after all the suggested troubleshooting. The battery life is horrific and takes forever to charge so it almost permanently lives on it's charging station. Sometimes it takes 10 minutes or more just get it to stay paired to my phone which is either an app issued or a mug issue as it is the only Bluetooth product I have this issue with. It is supposed to remember your preferred temp, but only does that about 1/3 of the time. There have been times off the charging station that even when paired and with the heater on and a 75%+ ...

There have been times off the charging station that even when paired and with the heater on and a 75%+ battery, it will say it's at 139 degrees but my drink is lukewarm or cold. Problem wasn't fixed with re-pairing or keeping it on the charging station, it just randomly decided to start working again a few days later. Cannot use it for lattes as it burns the milk at the bottom, even at the suggest temp on the app. That part isn't as big of a deal because WHEN it works, I'm fine keeping it solely for brewed coffee and tea.I just wish it WORKED more than 65% of the time especially at the price point it's sold at. This product has potential, but as is I would encourage anyone I know that is thinking about getting it to save their money.
This mug is not for you if you gulp down a cup of coffee in ten minutes. If you spend your afternoon nursing that one cup you poured after lunch, consider the following. The Ember Mug does hold the temperature of your coffee for about 60-90 minutes on one charge. The functionality will last all afternoon if you put it on the charging coaster. However, I do have some warnings. Nursing your beverage over time will lead to the last few sips being VERY HOT since the mug keeps heating independently of the amount of liquid in the container. If you like cream and sugar in your coffee/tea the effect mentioned above will turn your last remaining sips into something between cream cheese and Creme Brulee.

The best use of this mug is keeping it on the charging coaster and refilling the mug when you have finished half the cup.The charge coaster needs an optional USB cord for charging. Often, there is never a convenient electrical outlet or space on a power bar for the charging coaster's adapter. Using a USB port on a laptop would make this the ultimate travel accessory!
I bought this mug just prior to Covid and I have been using it almost daily since minus some weekends. My friend had the original Ember Mug and did not like it but I bought one of these anyway due to specs and looks. Things I don't like: The most annoying part is cleaning it daily using what I feel is the most non-abrasive sponge and regular dish detergent and once washed, waiting for it to dry completely as the rubber rings on the bottom tend to retain a little moisture and I don't want the contacts to corrode because of it. The Bluetooth doesn't rerecognize with the app very well. I thought it was my hardware (aka phone I used) but I've tried 3 different phones and one tablet and I find the same issue so I'm just now blaming the bluetooth on the mug. but once ...

The Bluetooth doesn't rerecognize with the app very well. I thought it was my hardware (aka phone I used) but I've tried 3 different phones and one tablet and I find the same issue so I'm just now blaming the bluetooth on the mug. but once you've set it to the temp you like, even when it disconnects, it retains the memory so that part is good. I've been caring for this cup as instructed and It's lasted me this long. I have the black one and I am starting to see the paint? coming off from the bottom of the cup? I think it's just the paint. It looks like small speckles. I am assuming it's from the hundreds of washes and the heating element. Also My battery only lasts about 20 minutes now but it's also been 3+ years. Final thought: It's still an expensive mug! But it works way better than any external heaters, It looks nice, they did a great job in balancing out the weight to usability ratio. I thought it was pretty heavy at first but maybe I got use to it. But more importantly, when I get so consumed in work and I lose track of time, My mug keeps my drinks warm and at a good temperature so I am very happy. So happy actually that now that I have to go back into the office, I am thinking about getting a 2nd one for the office. I am wondering if the metallic is painted or not. If not and it's an actual metallic coat, ....I might have to cough up the money to get one. I hate tumblers, but I also do not like cold drinks that are supposed to be hot and I don't want to keep reheating as that also takes time. Lets just say I like this mug so much I am almost willing to buy my friends one who experience the same frustrations of unwanted cooling of their drinks (as long as they have the patience for the caring and maintenance aspect of things).
I purchased this after doing quite a bit of research between a few different brands. I landed on the Ember because of its Bluetooth connectivity.Most mornings I finish my tea in 45 minutes, but there have been a few times where I lingered sipping longer than the charge on the mug. At first I thought this would be a problem, but it’s not.I also have a “favorite tea mug” which I sometimes start with (bc it holds 16 ounces vs the 14 ounces of the Ember. When it gets cold I simply transfer the tea to the Ember and let the mug reheat it to my perfect temp.Most mornings though, I start and finish with my Ember. I no longer get up 4-5 times to reheat my tea in the microwave - which I am so happy about!On a perfect morning the Ember keeps my tea hot to the last sip ...

I have to remember to “pair” my mug up - which I didn’t know would be “a thing”, but perhaps this is “user error”, however it’s certainly not a deal breaker.Overall I’m very pleased with my purchase. I do wish it was a bit bigger by 2 ounces (but I’m probably drinking more tea at one sitting than most).I do also wish the charge lasted longer, however this does not take away from the experience of no longer needing multiple trips to the microwave to reheat my beverage - most mornings I am finished with my beverage before the charge is out. The mug does alert you to your charge status, which is nice.So yes, overall I’m happy!
If you ever drank coffee out of a glass pot that was on the burner for about an hour, you know it has that burnt/scorched taste.... that is what the Ember mug will do but in 15-20 minutes. It does these even at low temperature settings.Full disclosure, I do not typically put cream in my coffee, which will mask the burnt taste a little longer but not much.Now, for tea, this isn't an issue because steeped tea leaves work different than what extracts from coffee beans.With all Ember products (particularly the joke of a travel mug that is 12 oz), the size is too bloody small. Who really needs a mug to keep a 10 oz beverage hot because you'll drink it quickly.... this product would make sense more for a 16 to 20 OZ serving, but the largest is 14 oz which is ...

Who really needs a mug to keep a 10 oz beverage hot because you'll drink it quickly.... this product would make sense more for a 16 to 20 OZ serving, but the largest is 14 oz which is literally to the brim so in the 14 oz you're only really able to put in 12ish oz without spilling and 8-9ish in the 10oz making the sizes even more unacceptable for the price point.... which is EXPENSIVE for a mug that burns your coffee and will look like crap after a few uses as the cermaic scratches easily.For the price point, the internal coating could be more premium to reduce staining since you can't put it in a dishwasher and have to gently hand wash. I do find dropping a Cascade pod in the mug will remove tea stains after a short soak. Unlike others, I've had app connectivity issues which is good.... but there are other mugs that do this in larger sizes for a lot less money.Really sad that Ember has never really innovated new models to be better because they were on the right track with the first versions. For the price, a soft heat approach that isn't just a burning hot coil in the bottom of the mug is what one should expect and that is not this mug or any of their products.
I have had my ember mug for over 3 years, now -- it got me through all of the pandemic, where I was home every single day and using the mug for my daily morning coffee. It's finally time to buy another, but not because the mug has died completely. It has actually continued to work (at least for my weekend brews) for the last few months, it just doesn't warm for the duration of time it used to. It was capable of keeping a drink warm for about 2 hours on a single charge for the first few years; the last few months it started decreasing in how long a charge could hold temp, down to about 20-30 minutes. This along with an issue with the internal coating chipping are the reasons I'll be replacing. I would personally say this mug is completely worth it. It's just a matter ...

It's just a matter of time before these things die (as with all electronics), and this mug had a really good run at 3 years, with nearly 2 of those years being abused with daily use. Note: I never bothered with the app -- the standard pre-programmed temperature was perfect for me. Those who want the app may have a different experience, but if you just want a mug that keeps your brew hot for 2-3 hours, I think you'll be very happy with it.
