Good cup for work distractions
Owned for 2 months when reviewed.
My husband bought this for me since my coffee always gets cold especially when I am working. I work from home so sometimes I get busy and distracted and I dont get to my coffee quick enough. I wanted the bigger size as that is the type of cup I normally drink. The pros are that is definitely does what it says in keep your coffee warm. You have several different settings within the app to choose from on temp.level. It was extremely easy to hook up to the app and I havent had any issues since. Within the app you can check your battery level. Since I do work from home, I thought it would be best to just keep the cup on the charging pad, but I started noticing that the bottom of the cup started to become discolored. I was a bit worried that it was because I was charging and the heating element were being used too much together, so now I only charge when needed. I dont trust charging it while I am sleeping or gone with that discoloring. I have tried to wash it thinking it could be from something else, but it doesnt not come off. The biggest con is I do not think it keeps a battery life as long as it says. It does seem to lose battery quickly. It is also really hard to make sure it is off just by the press of the button. It seems to light up as soon as you pick it up or move it. The coffee does get an old taste if it has been sitting for a while just like it does in the coffee maker, like over cooked. I was hoping that wouldnt be the case. I use this cup every day during the week that I am working. The rest of the time I use regular cups. I think this would be ideal for someone who doesnt drink their coffee fast or gets distracted easily and comes back to cold coffee often. It is on the heavy side. Definitely bottom heavy as that is where the battery and heating element are. It must be hadn washed and dried quickly. You dont want to leave the bottom wet.
I would give this more like a 3.5 star. It definitely controls the temperature of the liquid you put into it but it does not make it warmer. So just be aware of that. I was expecting the coffee to be just a bit warmer and for longer. So I am not over-the-moon about it. But it is much better than just having your coffee continue to cool. However, I'm not feeling the value for the money. These things are not cheap. And the enamel in the bottom of mine has already started to come off just a bit. Not sure how that happened. I thought it was baked-on coffee, but it's the actual material that's rubbing off the inside of the cup. For $135 for a mug, I would have expected much better quality.

The mug I have been looking for!
Owned for 2 months when reviewed.
The mug I have been looking for! Now that I work from home occasionally, I found that my coffee got cold during work calls (because time flies). This mug keeps coffee hot for over an hour, and it even charges on its stand with coffee in it. Very happy.
How have I gone this long without this cup!? I am a slow coffee drinker and therefore I’m constantly warming up my coffee in the microwave to get it back up to the temperature I prefer. This cup truly keeps my beverage at the same set temperature long enough for me to enjoy every last drop and at my pace! Love, love, love this cup!
“I like my Coffee HOT!” I purchased this Ember 14 oz coffee cup fro Best Buy after seeing my Daughter-in-Laws’ at her house the other day. She told me that her every drink was “Piping Hot!” I was SOLD! Get yerself One!
I would recommend this to a friend

This mug worked really well and was a good size. However, now after 4 months (beyond return period) the paint or glazing is peeling off the inside making it unusable. So that was $32/month for a coffee mug. :(

So I was super excited to get this! I just had a baby and my husband would leave my coffee on my nightstand and sometimes when I’d wake up, it was cold. When I came across the Ember I was stoked! Come to find out that the battery lasts like an hour. I did, however find a solution which is to leave the charging station by my nightstand some it’ll remain charging while on it!! So now I can wake up and have my coffee at my favorite temperature!! I love that I can control it through my phone and it alerts me when it’s reached my temperature and when it’s low on battery. You can also choose a light color, kinda like a mood ring!
Always wanted the mug ever since my husband got his . I love how it gets my coffee to the perfect temperature how it stays that temperature thewout drinking it . I also love that it changes colors . It’s easily washable. Cools down quick and fits Nicely on my dresser . Highly recommend this cup ! Never going back to my normal ones again . I’m hooked being a huge coffee drinking this mug is my best friend to keep it nice and warm thewout my time drinking it !
A:AnswerHi there, thanks for reaching out! The charging coasters are interchangeable and laterally compatible to each mug. Both charging coasters use the same charging technology so you can charge the Ceramic Mug (both the 10 oz and 14 oz) on the Travel Mug coaster and vice versa!
A:AnswerThere's no burnt flavor. The element heats very evenly, so there isn't that burnt flavor that happens like you'd get when you leave a pit of coffee on a heating element. The biggest thing I notice is A) If you leave it in there a long time and use half and half, the heat will separate the fats in the half and half and they float to the top and make a film. I now use fat-free half and half and don't have the same issue, but I notice after an hour or so the taste does change a little, almost like it's the cream that's getting old from the extended heat. But if you drink faster than an hour, it doesn't create an issue. B) If you do use cream and leave a very small residual amount in the mug, it will continue to heat and form a sludge. Though it's easy to clean with some soap and water. I still highly recommend the mug. I like not having a cold cup of coffee sit there and go to waste as I'm working.
A:AnswerNo. This isn't a heated base like you'd see for much cheaper where it heats the mug directly. The ember mug has an embedded heating element and rechargeable battery in the base. The reason for the base is to recharge the battery, not heat the mug. The heating is handled by the mug itself.
