    Didn’t think I needed to keep my coffee warm because I’ve always been fine with drinking it after it goes cold, but after using my Ember mug for about a month now, I appreciate the constant warmth — especially during this cold winter. Paired easily with the App on my phone, and easy to choose the temperature setting. I’ve been careful to take care of the mug by using a silicone spatula for stirring (metal spoons can cause cracking in the “ceramic” coating) and rinse and dry it afterwards to avoid coffee staining. The only change I would make is buying the next size up because I learned 10 oz doesn’t allow room for creamer.

    I heard about this mug years ago and laughed it off. There was sale so I purchased lol, I use my Ember Smart Mug daily! The app is easy to use. The mug keeps liquids hot. I have put cold liquid and it heats up to 135 degrees. I wish the larger 14 oz. was available for purchase. I originally ordered gold but exchange for copper but both look great.

    I purchased a second Ember device for home because I liked the first one I got for the office so much. It’s simple to use and I look forward to slowly sipping my coffee. The only downside is that I should’ve splurged on the larger size. I tend to drink my coffee black but I do like to add milk to my tea. I don’t think the smaller size is adequate for drink and add-ins.

    I really do love this little mug because I’m really bad a making a cup of coffee or tea and forgetting about it until it’s cold. I can set my perfect temp and it keeps it there. My only complaints are the cup is smaller than I like and it doesn’t charge with something in it if you put it on the charger.

    I’d initially purchased one for my wife who’s a daily coffee drinker. After she used it, she purchased one for me for Fathers Day and I’m so glad she did. Getting early morning coffee Mon longer requires multiple microwave reheats be sue the cup really does keep the coffee nice and hot! I highly recommend this this one!

    Works well 90% of the time

    I’ve wanted this mug for a long time. I’m one of those people who keeps traveling back to the microwave 2 or 3 times per cup of coffee. My experience so far with the ember mug is that it works, but it’s quirky. Most of the time it’s great. It’s wonderful to be able to pick up my cup of coffee 30 minutes after I’ve poured it, and have it be wonderfully hot. Problem is, this mug sometimes gets confused: The temperature will unexpectedly start dropping. Sometimes it recognizes it‘s mistake in a couple of minutes. Other times the app will say it’s 145° as it gets cooler and cooler. Sometimes that will eventually correct itself. Sometimes it won’t. So, with the mug I have, I have to use the reset button every 10 days or so for it to work. By the way, I had to replace the first ember mug I bought. It had the same behavior 50% of the time. Based on my experience, in the mixed reviews I read, there is a quality control issue. But I’m keeping the mug, after some struggle. I like the way it looks, the nice hot coffee most of the time. As others have said, a $100 mug shouldn’t act this way. But pressing a button every now and then is worth it to always have my coffee hot.

    Great idea and color, but too small and expensive

    I love the idea of this cup and it is better than other ones on the market. The color is awesome. However, I have two complaints'. One, the 10 oz size is just too small. The Keurig fills it all the way to the top, there is NO extra room, and as soon as you pick it up, it will spill. I don't want my coffee any stronger than the keurig being set for 10 oz. So one would say buy the bigger cup, however the bigger cup cost a fortune. Which leads me to the next complaint, it just cost too much. They should make only the 14oz and price it at the 10oz price. All in all, I like it, but would not buy another one unless it was the bigger size for under $100.

    This is the best gift I ever received for my morning coffee at work. Coffee typically gets warm, then lukewarm, then cold as I take too long to drink it as work mixes with my coffee time. Ember solved all of that for me. My coffee stays at a consistent 135 degrees through the entire cup regardless of the time frame. It’s the best!

    Okay, much better than expected. If you're looking at this you know what it does. It keeps you liquid refreshments at the temperature you want for much longer. It works very well. What was striking to me at first was the weight and seeming quality of the mug itself. Fantastic. Battery life feels a little short, the best use seems to be using the charger as a coaster next to your favorite place to imbibe. You will get more than an hour of life off the charger, but it's really nice to just put it down and keep it hot. Highly recommended.

    The cup is durable and has a nice finish. Holds a charge and heat well. I use it daily. Only wish it was a little larger in capacity. Will most likely purchase the larger version with lid.

    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.

    Got for my daughter who always likes her coffee hot while she's drinking a few cups during her work meetings. She loves it! So I decided to get one for myself BUT I use a Keurig coffee maker, always making an 8 oz size cup--problem is I like a lot of cream so I realize the 10 oz cup will be too full, need to get a 14 oz Ember mug! Hopefully it will be on a Deal of the Day soon!
