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!

Love this! It does a great job at keeping the coffee the perfect temperature. The warming lasts for about 1.5 cups.

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.

This was recommended to me by a good friend of mine that also has an infant and it truly is remarkable considering I can no longer have my coffee in one sitting . Greatest invention ever!

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.

Best coffee cup ever! This is the best coffee cup that I have ever had!! I will never go back to cold coffee again!

Best purchase I’ve ever made as a daily coffee drinker!!! I love my Ember mug. It was given to me as a Christmas gift. I am very happy with it and I use it daily.

I love it and useful to keep your drinks hot you can adjust your ideal temperature.

Wife loves the product. It’s durable and we have not had any issues with it thus far. I am a slow coffee drinker so it occasionally comes in handy when my wife is not using it.

I got this for mom for Mother's Day. She loves it! She loves coffee! Worth it!

Makes for a perfect cup of coffee! Easy to use and maintains an ideal temperature.

Love, love this mug. Keeps my coffee perfectly warm for a long time.

Love love love the price is pretty high but I use this cup everyday

The Ember Mug not only keeps my coffee hot, it ensures every sip will be the same temperature as the last. (Until you get to the bottom

I love it, so far my favorite cup. It works very well.

I love this cup. Such a thoughtful gift from my daughter. I use it everyday.

Works great and keeps drinks warm! Definitely recommend!

Awesome product. Having consistently hot coffee is way undervalued.

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.
