[This review was collected as part of a promotion.] Beware of warranty fine print regarding corrosion. Bought mug for less than 2 months and got corrosion on the bottom of cup and on the charger. I cleaned and dry every time before charging. I don't write review but with expensive item last 2 months only. Contact customer support and corrosion is not covered. Within 2 month it's $130 junk. Reply from Ember Support: Thanks for reaching out and providing these photos. Sorry to see this happened. From the images shared, it does look like there is some corrosion damage on the bottom of the mug. While corrosion is not covered under warranty, here at Ember we want to support our customers as best we can and offer an out of warranty replacement for the mug at an additional fee.

[This review was collected as part of a promotion.] This was a birthday gift for my wife. She isn’t much into tech items, but she loves her morning coffee. She absolutely loves this coffee mug and hasn’t used anything else since getting it. It seems to be high quality and easy to use. We linked it to her phone and she enjoys getting texts from the mug. Attached is a picture of a text she just got saying the coffee is ready. We originally got her the 10oz mug but it didn’t leave enough room for her massive amount of creamer she likes to use so we upgraded to the 14oz one which is perfect. She likes that this mug helps keep the creamer from cooling down the coffee. We highly recommend this mug but it is a little pricey.

[This review was collected as part of a promotion.] 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.

[This review was collected as part of a promotion.] The Ember Mug is a game-changer for anyone who hates lukewarm coffee or tea. It keeps your drink at your perfect temperature for hours, which is fantastic for slow mornings or long work sessions. The app is easy to use, and the charging coaster is convenient. It's a splurge, but if you value consistently hot beverages, it's worth it.

[This review was collected as part of a promotion.] The Ember smart mug is pretty good but not great. The 10 oz is not big enough but the 14 oz is too expensive. I would definitely buy the 14 oz version if money is not an issue. It’s too expensive for what you get. That said, I make a cup of coffee in a 15 ounce cup. When the 15 ounce cup starts getting cool, I dump it in the 10 ounce Ember mug. Not very convenient. The battery is really bad. Believe the other reviewers when they say this. You must keep it on the charging station if you do not want this to die. If they can make a 14 oz cup with a long lasting battery at a reasonable price, this could be an awesome mug. I’m giving this 4 stars instead of 3 because the app is awesome. Pairing is easy. It will alert you when your coffee is at the correct temperature and if you can keep it on the charging base, you will not have issues. The app has presets for tea, water, coffee, etc. Overall the mug is pretty good, but consider buying the 14 oz version if the price decreases.

[This review was collected as part of a promotion.] I really like the way I can control the temperature of the liquid in this mug. Best part is that I can place this mug down anywhere and it will keep my beverage at the exact temperature. I am also notified when my beverage reaches the desired temperature.

[This review was collected as part of a promotion.] Received the mug as a gift. Overall it's okay, but expensive for what it is. It's a 10 oz mug to its brim so it only holds about 8 oz of fluid if you want to be able to carry it without spilling content (from the kitchen to your desk). I've had problems with the app and the mug disconnecting and that's a problem when the mug is full of hot fluid (press the bottom button to reconnect). Ideally you need to stir it, or give the mug a swirl as you drink (empty) the mug since the fluid at the bottom gets noticeably hotter the lower you get. There is some guilty pleasure when you finish something, reach for the mug and your drink is still hot.

[This review was collected as part of a promotion.] So far it's amazing but an 8 oz keurig dispensed with cream and sugar does not fit this very well I would go with the bigger size if you like cream in your coffee ! But it has definitely kept it cozy!

[This review was collected as part of a promotion.] Poor design and execution, just buy one of the much cheaper mug warmers. The battery only lasts about an hour, so it's never far from the charging base anyway. The one light, one button design is a real pain and makes it difficult to tell if the mug is on or off because there doesn't seem to be a way to completely turn it off. The light will pulse if I move the mug at all, even when not actively warming. There's no battery indication on the mug itself, you have to use the clunky app. The charging base isn't waterproof, so be careful of any spills. And instead of using wireless charging it uses two metal contacts that have to line up exactly with the mug.

[This review was collected as part of a promotion.] Granted. I never really used it before I was pregnant or had my baby. Now that I am a busy mom. Constantly using it. Especially when I am trying to do all chores and handle a baby. There are times when I do forget about my drink. It would suck when I used a regular mug. Constantly having to reheat. With this mug, i am able to do everything, even have moments I forget I made tea or coffee and when I am finally able to sit down, I can enjoy it hot still. Granted, if its not on the charger, it will die before I can get to it and start to cool down. But i always leave mine on the charger and its great. 10/10 recommend.
