Ember Temperature Control Smart Mug 2, 14 Oz, App-Controlled Heated Coffee Mug with 80 Min Battery Life and Improved Design, Gray

Love it

Especially if you’re a slow drinker

Randomly switches off whether it's on or off its saucer. Randomly stops recognizing whether it's filled or empty. Just unreliable all around. I bought it based on a friend's recommendation (perhaps mine is defective, as my friend raved about his). Sadly, I threw away the box, so I didn't try claiming a return. All-in-all, my advice: don't waste your money. Just reheat your coffee when it gets cold, it'll take a few seconds instead of fiddling with this unreliable mess. Also, the decision to use a proprietary charging port instead of USB-C is silly anti-consumer practice. It forces you to carry the charger with you as you move around your house, instead of being able to use the USB-C cables already in different rooms. This is clearly designed to extract more money for extra chargers, especially frustrating when you've already paid a premium for an overpriced mug that doesn't work most of the time and is excruciatingly slow to heat when it does work.

The good: it’s really nice to have your coffee stay at exactly the right temperature. It gives me that ‘living in the future’ feeling. The bad: 1. The battery doesn’t last long enough. I use the lid and that helps a lot, but it also takes away from the magic. And even with the lid I wish the battery would last longer. If I am at home all day and want two hot drinks, one in the morning and one in the afternoon, I’ll have to recharge between drinks. 2. The app could be better. It will sometimes log me out and having to repeatedly log in to use my mug is quite dystopian. I also immediately disabled notifications because that is such a bizarre feature. But then the downside is that I might not notice when the battery has drained. And it’s jarring to drink from this mug and find that the drink is cold (because you get used to it always having the same temperature). 3. The charging pad is fragile. I accidentally broke it while cleaning it (I thought I was gentle) because the copper contacts are very fragile. My phone and my toothbrush can charge wirelessly and it’s weird that Ember mugs don’t charge that way too. As I mentioned, I do like the mug. However, my charging pad broke and I won’t be replacing it. If they release a new mag with double the battery life and wireless Qi2 charging then I may reconsider. They also need to make the app more robust. For now I’m happy to use a well isolated mug instead. Finally, I should mention that I tried to contact their customer support multiple times to check if the charging pad damage was covered by warranty, but they never even replied. Given how expensive this mug is, I’d certainly expect better service.

Stopped working after 6 months

Ember cups are a fantastic concept and incredibly useful, but I’ve encountered some challenges with the company's aftercare service. It's frustrating that I've had to rely on Amazon for repeated replacements of my cups. For users who utilize them often, it can become a hassle to request repairs or full replacements regularly. It’s disappointing, especially considering the investment. I hope the company can improve their customer support to match the quality of their product!

Got this for my wife who likes sipping on warm beverages for extended hours, often throughout the day. Up until now she’d keep making or reheating cups of green tea, coffee etc over & over or worse yet, get me to do it! ;) But this changed all of that. Couldn’t be happier. Does everything it claims. The wife loves it. She said it’s changed her life. Might pick up another one just to be safe :)

Not really much to say here, yes these mugs are expensive, all I would say is keep watching the price, normal retail is £149, I have seen the 14oz grey version drop to as little as £99, kicking myself for not buying then, I took the plunge when saw back on offer at £119, the mug itself works flawlessly, I never turn it off manually and goes to sleep as soon as it’s empty and wakes up once a drink is poured into it. The app which I am using on iOS could be much better, it very rarely automatically connects to the mug, however this is not a issue as once you’ve set your desired temperature the mug will remember those settings and the white led will remain solid once that temperature has been reached. I find the mug very easy to wash, I am mainly using with Tassimo coffee so even after being left a couple of hours and there’s a ring round the top of the mug it cleans off very easily. I read previous reviews of folks complaining that the mug marks easily from spoons, so with that in mind I am using wooden tea spoons and can confirm no marks as yet.

Fonctionne très bien. J’aime beaucoup mon café chaud. Très heureuse de mon achat.

I love this thing! I work from home and like to sip hot tea all day. This device keeps hot beverages at the perfect temperature—which is handy for slow sipping or when I make the tea, then get busy and don’t drink it right away. The battery doesn’t last a long time on its own, but it’s fantastic to use all day on the power/charging coaster. With the app, you can set your preferred temperature and the device will maintain it. Safety feature: Will shut itself off if not moved/lifted for a long time. It seems frivolous, but it gets daily use and I don’t have to keep remaking tea because it never gets cold with this handy device.
