Customer Ratings & Reviews

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.

Like most of us these days, I am working from home and using coffee cups instead of travel mugs. Naturally, I am a slow drinker, and I hated that my coffee would always get cold before I could finish it. Then I found the ember 10 oz mug. I'll admit, the price is high, BUT, for me, it has ended up being well worth the price. Ever since buying this mug, I have finished my coffee and teas without any waste. For me, the less than desirable battery life doesn't bother me. Because I work from a desk, I am able to leave the cup on the charging pad which will keep my drinks the perfect temperature all day. If I don't have the mug on the charging pad, I am able to get over an hour of 140 degree coffee or tea. I liked this product so much that I ended up buying one for my mother as a gift and will likely buy the travel mug in the near future.

Design is sleek and it connects easily to the app. It definitely can keep tea warm for hours when plugged in. It takes a while, probably 10-15 mins, for a hot tea (~200F) to be reduced to drinking temperature (~135F). So it's about the same as leaving it in a normal cup. It also can't hold that much liquid; definitely holds less liquid than a regular size ceramic cup.

This cup keeps your coffee at the exact temperature that you like. You can set the temperature hotter or cooler than the factory preset temperature. It keeps your coffee at the temperature you enjoy for several minutes until you get your refill.

Excellent Smart Mug. Modern and stylish design, long-lasting battery that allows me to enjoy my coffee at the perfect temperature all day.

Great mug to keep my coffee hot! Got the stainless one because the plastic looking ones just looked cheap and they were almost the same price. The battery lasts about two hours. Normally, it won't take me that long, but I happen to leave the house one time and came back with my coffee still warm. The app said the battery was depleted and gave me the temperature. It was only off by a few degrees, so I figure two hours was about it. My cons with this: 1) the price. It's expensive for a mug. 2) At the time, this was the only size, 10oz. That's way too small. All my mugs are 12-16oz. This won't even hold a large brew on a Keurig. Huge negative. Now they have a 14oz one and, of course, you're going to pay for those few extra ounces.

This works so well! I would recommend getting the larger size, as this is not the standard cup size. However, the charge lasts a long time and keeps the coffee so hot!

Love this cup! I enjoy sipping coffee while it is hot and I don’t want to have to gulp it down in order to drink hot coffee. The new improved ember keeps coffee hot for at least an hour at 141 degrees.

Sleek and premium! Coffee stays warm for long! Worth it and perfect for a gift.

This mug is my husband`s saver )). He cannot drink warm coffee, which is getting cold so fast in the normal cup. This mug is keeping his coffee for so long. My happy hubby thanks to Ember mug))!! Definitely amazing purchase and highly recommended!

The conveniences and benefits come at the cost of one convenience, and it's that washing and caring for this mug is more of a hassle than for a regular/dishwasher safe mug. - it is also quite expensive. Though the cup can be safely submerged in water for the purposes of cleaning, water does seem to seep in between the rings and silicone base. Also, the stainless steel does stain very easily with turmeric-based teas and is very prone to scratching from cleaning pads, so be careful about that. I will give my personal wash/care routine at the end of this review for anyone interested. The reason why I still give this cup 5 stars is that it has two major benefits. The first is the obvious one, it keeps beverages nice and warm. I love that I never have to make trips to the microwave. I generally keep the mug on the charging coaster as this is necessary to keep beverages heated for longer than 30 or so minutes. However, the other major benefit, which I initially didn't anticipate, is that I never burn my tongue or expose myself to damagingly hot beverages when using this cup. It always let's me check and make sure that the tea I brewed in it has cooled to a safe and enjoyable temperature before I take that first sip. And then, it keeps it at that temperature! I will say that this cup is less effective at heating drinks up. This is because, unfortunately, it seems like the sensor in the cup gets confused when the temperature of liquids in the cup is equal to the temperature of the room. It thinks the cup is "empty" and stops heating the liquid up. It would be great if Ember could develop a "Heat" setting/function on the app, to let the cup know that there IS liquid in the cup and for it to keep heating past that room temperature confuse point. Now onto care/use guidelines: I usually only use this mug for straight teas and avoid putting milk or other additives that might burn or stain the bottom of the cup. I wash by shooting water up into the cup while holding it upside down to avoid getting the base wet. Then I wipe down with a microfiber cloth.

Great coffee mug for my WFH mother! No more having to get up and go to the microwave to keep reheating. Keeps it hot and fairly fresh vs that reheated coffee taste

I have bought several of these the last 6 years. All are still working, But, the interior paint(?) in the inside is coming off from the only white one I have. The black one seems to be fine of the same age. You should also know the chargers start to fail after a few years, but can be fixed with a soldering iron if you are up for it. I recommend these to every person who asks about it

I gifted the Ember Temperature Control Smart Mug² – 10 oz in White to my wife for Mother’s Day—she’d been wanting one for over two years, and it didn’t disappoint! Sleek, well-designed & app-supported – The app lets you fine-tune the temperature, choose LED colors, and even use steep timers and presets for different drinks.

Perhaps I am not understanding the directions correctly but this is not working reliably. It is sometimes tempermental in the length of time my coffee remains at drinking temperatur especially when after being charged it sits on the holder.for several hours. It shuts off even though the light shows its on. Dont like the idea that it takes 1 1/2 hours to fully charge. Cannot be used for my first cup of coffee in the morning and dont want to leave it overnight charging. Will be calling Customer Support before returning.

I bought this for my wife, we have small kids and coffee is always cold, she loves it and keeps her from using the microwave every 2 minutes.

The mug does maintain the temperature of 145 degrees, once it is set up. Some may prefer their coffee hotter, I'm OK with this temp. For me the app is useless for a couple of reasons. Most important and annoying is, mug loses contact with app(on phone) and the app will not complete the update it insists is available. Loss of contact with the app has no effect on maintaining the temp. Lastly, the inside of the mug stains quickly. To me it's just a coffee mug, so I don't care. The ladies may feel differently. All said and done, it does do what it claims,,,,,, it keeps your coffee hot, for about 75 - 80 minutes. I would buy it again.

For a slow cafe drinker like me this cup is amazing, I follow an IG account and realized she had one of these and got me curious to wanted to try, Keeps my cafe warm without having to reheat and that I like a lot.

Great coffee cup. Wish I would have gotten the 12oz because there’s no room got creamer. Keep coffee hot, must stay on charger for charge to last

This is my second Ember, which I bought to supplement the one I have. On the days I want two cups of coffee, sometimes I don't want to wait for one recharge before I start my second cup. On the charging pad, it will keep coffee warm all day, but off the pad, the limit is about 90 minutes. The thing I like best is that I get to set the temperature I want through the Ember app.
