    Fantastic mug with just one flaw

    Let me start off by saying this a one of the best mugs for coffee lovers. With that said, the only two negatives I have to say will be the price and battery life. For the obvious reason, $150 is a little steep for a any mug/cup. It serves a purpose, so there’s not too much I can say. The battery life I wish was a lot better than what you get. It ranges between 2-3 hours. So if you’re someone who likes multiple cups, relaxing and drinking outside, or keeping at your desk while working you’ll definitely have to consider that. The few hours may seem like a lot of time but trust me when I say you’ll get plenty of notifications that your mug needs to recharge, which is slow to do that as well. It may not be perfect but it’s still a great cup.

    Love my Ember mug! Its a game changer, as my coffee stays hot all day if I leave it on my coaster. I also got a lid for it, not overly impressed by Ember's official lid, it isn't leak proof but it does extend the time the battery lasts.

    My dream coffee mug....

    This is an amazing little coffee mug. I have been waiting for like twenty years for someone to come out with a dependable self-warming coffee mug that actually worked and kept your coffee HOT. I mean steam comes off the coffee the entire time (I have mine set for 145 degrees (max). I will opt for the optional lid, too....as it makes it great to take on hikes, in the car, etc...not to mention it saves on the battery because it stays hot easier. At $99 sale price, it's still pricey, but honestly, I'd buy one again if need be. Bonus: I love the dark blue color, which was the only one on "Deal of the Day". Win win!!

    I was introduced to the ember mug at a friend's house. He served me lukewarm coffee, and it just got hotter as I drank it, which even when you know this beforehand, it's still an unusual experience. I bought one for my wife, and she has become a big fan, because unlike me she takes her time drinking tea or coffee and it remains hot the whole time. The mobile app connected to the mug with no issues, and you can see the temperature. A very useful gadget!

    Hot Coffee All Day

    Keeps my nespresso hot and fresh all day while working from home or in the office. Bought this on sale for $50 and highly recommend buying at this price. Knocked out one star because if the cup is at highest heat setting, it will drain the battery in less than an hour. Not great for traveling but just fine if the base plate is nearby.

    Good cup for work distractions

    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.

    Keeps coffee at correct temperature for about an hour depending on how high. I wish the battery lasted a little longer, but it’s usually okay. The inside of the white mug is already staining after about a month if use.

    I’ve been thinking about purchasing an Ember Mug for awhile. It was featured at a great sale price and it was delivered the next day. I didn’t realize how much better my coffee tastes kept at a higher temperature and never getting cold. Controlling it via Bluetooth is fast and efficient. It doesn’t take long to reach your chosen temperature. I use this every day two or more times a day so definitely getting my money’s worth.

    I love this mug! If you drink any sort of hot beverage this cup is a game changer. I can’t tell you how happy I get inside when I take a sip of tea thirty mins later and it still gives me the feeling that first sip did due to it being warm. You can pick your temperature for your beverage on the app. It even has presets of certain teas that should be kept around certain temps. Worth every penny! You can even change the light at the bottom to different colors incase you have multiple people drinking out of multiple cups!

    This is my second ember mug, and it's all i use. It keeps temperature for well over an hour and i can use it several times a day as it charges pretty fast! The sturdy, weighted bottom and the width of the handle make it the perfect cup

    If you are a hot drink drinker, then this cup is your shield, your defense from either walking away from that initial hot cup of joe (or whichever hot drink) or being distracted to come back to an unwanted cooldown of that precious pour you were just enjoying. This cup brings peace, satisfaction, and enjoyment, and makes drinking coffee that much more enjoyable. Thank you, Ember! Oh, and the Blue color make it even more joyful. (Find your color, find your peace.)

    My sister purchased me one as a gift - it is incredible! If you like user friendly tech, this is your new coffee mug. I like to take my time drinking my coffee and am often interrupted, my coffee stays perfect! Never a burnt flavor or old taste - simply perfect. The plate stand charges the mug, the mug holds a charge, the mug will keep the beverage can be moved about an maintain the temperature. Also, temperture can be customized. Not for the dishwasher and no metal spoons for stirring - will cause etching on coating.
