    This is a perfect heating mug. After helping my mom install the app on her phone/ipad she never has a cold cup of tea again.

    Love this mug. I am a slow coffee drinker so having this mug keeps my coffee warm for quite awhile. I wish I would have gotten the 14oz. I would suggest a better manual.

    So it works fine without the app, but the app is required to increase the temperature. The reason i returned it is because the battery only lasts an hour or so. Unless you're able to set it on the charger in between sips, it doesnt stay hot long enough in my opinion. Its probably ok at an office desk, but just isn’t practical for couch drinking. Plus, you obviously can't microwave it so we inevitably end up transferring the drink to a different cup when the nattery dies.

    The Ember Smart Mug is so easy to use. So cool how it connects to your phone and you can control the temperate on your phone. Great for people who drink coffee slowly. Such a great gift idea!

    We love these mugs! Use them almost daily. They have different settings for different kinds of coffee drinks. The only knock is that the battery doesn’t last long. So charge it daily.

    Girlfriend has been using it every day since I purchased this for her birthday. She never finished her coffee since it got cold during her morning routine. Now this keeps her coffee warm and she can stop wasting coffee. Easy to set up with the app. Have washed it multiple times by now and still no issues with it charging or working.

    The product itself is okay but I’m not really a fun of it. A little pricey but overall the quality is good. I would say go for it if you have extra dollars to spend on.

    Does exactly what it claims it does. Very cool cup! Bought it for my mom. She had a bit of a learning curve using it (because she's just used to how she does things LOL) but she loves it. She does want a bigger one though. My only complaint is that the instructions are virtually non existent out of the box. You get very basic instructions and have to download an app for everything else. The app is very useful, but not everyone wants to download an app for a mug.

    This mug is amazing. I am currently a college student who is doing all of my classes online and having my coffee be at the perfect temperature all day simply makes my life a little easier. I used to always get up and microwave my cold coffee to the point it was too hot and by the time I let it cool, it would always be cold. I love being able to control the temperature on my phone. I recommend this product to anyone who is an avid coffee drinker!! Best Buy College Crew members receive products to write honest, unbiased reviews.

    Love this cup! I never accidentally reach over and gulp cold tea or coffee anymore. It reheats and, I can control temp from my phone too. Just wish the larger size was available.
