Customers find value in the temperature control feature as it allows them to set and maintain their preferred drinking temperature, ensuring their beverages stay hot for an extended period. They appreciate its user-friendly design, easy cleaning, and the variety of colors available. However, some customers have concerns about the battery life, size, and price of the mug, as well as the requirement of using an app to adjust the temperature.

    This mug itself has been fantastic. A self-heating coffee cup, the future is here! The app and bluetooth connection can be a bit fiddly but when it works its a dream. After having this mug for under a year and a half having exclusively hand washed it, the inside of the mug is flaking off. Just a few months out of warranty and it's unusable in this state unless I would want to inevitably drink whatever material it's coated with. I've reached out to their support team and am waiting to hear back but in any case I would encourage researching the coating flaking issue online if you're considering anything from this line.

    The technology is phenomenal it does what it claims however the cup is slightly too small at filling completely at the 7.76oz nespresso pod I use. I am unable to add creamer without fear of spilling.

    not a fan. $100 for a mug that is not dishwashable, cost 20x more than a $5 one, and make it feel like you basically only have 1 mug you want to use... just so that your coffee stays warm for like 30 minutes longer. you can even get a heated coaster for like 1/4th of the price on amazon, and it would work with ANY mug instead of only one, which you have to repeatedly handwash.

    This thing is wonderful for morning coffees - if you have an outlet near a side table the dock is great to have handy and not an eyesore. Only thing I'd say is opt for the 14oz if you're a heavy coffee drinker.

    A Smart Mug Made Dumb By Broken Software

    Posted . Owned for 1 month when reviewed.
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The Ember Temperature Control Smart Mug officially gets my award for Worst Product I Bought In 2021. First, let's talk design. The power button for the mug is on the bottom. Surely someone in the design process said, "isn't it a bad idea to put the power button of a mug on the BOTTOM?" Here's why that's a problem. My mug will randomly disconnect from the app and power off the mug. The only way to get it to reconnect is to hold the power button down to enter pairing mode. This is pretty tricky to do when it is already full of hot coffee. But okay, power button on the bottom for the sake a clean design. Sure. I get it. Everyone wants to be Apple. Take a look at my screenshots from just this morning. The mug attempted to update itself for the 4th morning in a row since I began using it last week. Sometimes it says the update is completed, but still it tries to update again the next morning. This morning it decided to disconnect while updating. What's really annoying is I have no way of knowing if the mug firmware is up-to-date or not because the app doesn't allow you take a proverbial "look under the hood." There's no deeper settings or device information to look at. It's either connected or it might as well not exist. Each morning it shows the mug in the app, but refuses to connect unless I select the "pair new device" button at the bottom. My experience with this mug, so far, has been an endless loop of bluetooth disconnection, failed updates and even app level errors (see my third image featuring "uncaughtException111," which is a deep level Java virtual machine function in the Android environment.) This is just good old fashioned broken software. Lovely. Folks, consumer electronics that are dependent on smartphone apps can only be as good as their smartphone apps. I'm guessing my mug is having problems because my Samsung Note 20 was just updated to Android 12. I'm also guessing that the folks at Ember haven't had a chance to check compatibility with Android 12 as it was just released in October 2021 and only just now for my specific device on my specific carrier. And that's okay, I get it. I've worked in software. QA testing takes time. There's a lot of phones, running a lot of different operating systems. But why, for the love of all electronics, didn't you just add some redundant controls somewhere on the mug or base? The idea is GREAT. A self-heating mug. Love it. But don't lock controls behind an app that you're responsible for keeping updated with the latest and greatest in smartphones. All you had to do was add a couple buttons to the charging base. A POWER button, a button for TEA and a button for COFFEE. That's it, three small buttons on the charging base that can control if it's on and two preset temperatures. No need to even get a phone involved unless you just really want a specific temp. Seems pretty logical to me, but what do I know? I'm no genius, but I'm pretty sure I'm smarter than this "smart" mug.

    I love this mug but after one month of using it, the bottom of the mug started to have a brown scratched up stain. After reading the reviews, I was so paranoid and never used a coffee stirer in it, I washed it by hand without a sponge or anything abrasive, and "babied" it like a delicate flower. Unfortunately, the stain appeared within a month of using it daily. Also, the cup is fairly small so if you drink lattes in the morning, I'd recommend going for a larger size. Overall, I really like the mug, just wish I picked a different color.

      Hi Gina, thanks for leaving a review here! We're glad to hear you've been enjoying your Ember Mug so far and appreciate the feedback in regard to the coating - we'd be happy to share this with our team! For best care and maintenance, we would recommend using a wooden spoon, or plastic/silicone utensils, if stirring and continuing to hand-wash using mild dish soap and a soft cloth. If you have any additional questions or concerns, please reach out to us at support@ember.com! Ember
