    High quality and useful mug

    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.

    Love the color of this mug. Does what it says and keeps hot drinks at desire temperature. It does heat from beneath so the bottom of your drink may be hotter than the top where you sip. Scratches easily if you use metal spoons.

    I cant say ENOUGH about this mug! I’ve been eyeing them for a year and when I bought one… I bought three more! They should be awarded “Best Gift of The Year.” Keeps my coffee piping hot and the app feature is easy to use. Thank you so much Ember!!

    It keeps the drinks warm. I do wish it kept it I bit hotter and for a bit longer. But overall gives a very pleasant experience of not having to drink coffee all at once

    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.

    Its more than a cup. It literally heats up. Then stays exactly how hot i want it to so i dont have to drink my coffee super quick like previous inferior cups have mandated before my coffee liquids get cold. No more cold coffee liquids!

    This item was a repurchase for me after the first one developed battery issue and was out of warranty. I drink a cup of coffee every morning, and I would often sat my cup down due to the coffee being to hot only to find my coffee warm and much too cool for my liking upon returning to it. That problem is a thing of the past with this cup. I can set the temperature I want and when the coffee cools to that temperature the cup maintains it very well. Perfect! I would have gave it 5 stars if I didn't have to repurchase it, however it's hard to make do without it!

    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.

    The charge doesn’t last very long. I like It, for about 1 1/2 hours. For $100+, I’d expect 3 hours or longer off the charger.

    I finally get to enjoy a hot cup of coffee from start to finish! And the color is beautiful. I keep it on the charging coaster on my desk while I'm working so I don't have to worry about battery life. The app also alerts you when you reach your perfect temperature-be it a latte, cappuccino, coffee, or tea (herbal or not). You just tell it what you have to drink and it will let you know when that temperature is reached. Or you can set your own temperature and you will get a notification when it's reached at well. Love it!

    The reason I gave it a four. Was because it’s a little pricey. It was a Christmas gift for my son-in-law. He takes it to work. He owns a gym. This keeps his coffee warm while he’s training.

    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.

    A smart mug is one of those things that sounds ridiculous at first but you'll quickly find out how awesome it is. I have a lot of distractions at work so it's helpful to have a mug that maintains the perfect temperature while I'm in a meeting.

    8 Oz keurig compatibility if you don't like cream

    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!

    I got this 10oz for my girlfriend. She loves it. Only issue issue I see is that 10oz may be too small, and 14oz may be a better option if one has a coffee maker than can’t vary dispelling oz amounts for small cups or big cups.
