Customer Ratings & Reviews

I am a slow coffee drinker and this is a life saver. I have one at home and at my office. No more sipping on room temperature coffee.

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.

I gifted this one but I love the embers and the colors are amaizing

I love the fact that this mug keeps my drink warm (to the temp I want it at) for up to almost 1.5 hours (yes I drink slow). The one downfall is it’s a little on the small side but it works for me. It works great though and I like it.

I work from home and while working I tend to neglect my coffee. I’ll go to take a drink and it’s cooled off. This mug keeps it nice and warm until I can finally finish it. No more trips halfway through to reheat my coffee in the microwave.

Wife loves it. Keeps her coffee at just the right temp! Where she used to have to microwave just to finish a cup of coffee, now thats a thing of the past!

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.

Keeps one cup at desired temperature but needs recharging for another cup.

Always wanted one. Got for a great deal as a Total Member! $100 off original price as the pick of the month for being a Total member. Paid $50. Like how it keeps my drinks at the exact temperature I want. Great battery when away from plate. If on the plate it has pretty much unlimited energy. Wish that on the Total pick you get to choose what color you want.

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.

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

Good product. It stay hot for over two hours on one charge

This is a good idea, but too convoluted. You need to connect it to wifi, app and outlet.

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.

Granted. I never really used it before I was pregnant or had my baby. Now that I am a busy mom. Constantly using it. Especially when I am trying to do all chores and handle a baby. There are times when I do forget about my drink. It would suck when I used a regular mug. Constantly having to reheat. With this mug, i am able to do everything, even have moments I forget I made tea or coffee and when I am finally able to sit down, I can enjoy it hot still. Granted, if its not on the charger, it will die before I can get to it and start to cool down. But i always leave mine on the charger and its great. 10/10 recommend.

If you're used to large mugs, do not think that 10oz is not large enough. After unpacking, I was initially tempted to return it because it looked small but it is just perfect. As someone who decided to reduce caffeine intake, I couldn't be happier: this is an ideal mug for hot drinks. Since coffee stays hot, I drink 2 cups instead of 8. How did I live without it? I love everything about this mug and if it continues to perform well, I will get the version for the car.

Easy to use app connects to the mug for customized temp settings. I leave mu coffee at 130 F and mug keeps it perfect for sipping over time. Also looks great on my home office desk! Is a bit pricey, but pennies added for each cup of coffee enjoye

The best part of my mornings is a hot coffee. I used to end up drinking it cold because I have two little ones to take care of. Not anymore! My ember mug keeps my coffee at the perfect temperature until I am able to drink it! It’s easy to clean, charges quickly, and holds its charge very well. It also heats up my coffee quickly if I pour it in cold.

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

If you're a slower coffee drinker like me, this is the perfect solution for keeping your coffee warm or hot the entire time. I usually sip on my coffee for an hour (sometimes more) and this cup does a great job at keeping it hot. You can set the temperature you want in the smart app and the cup will do everything for you. Easy to clean and return to the charger for later or the next day. I liked it so much that I purchased one for my son to drink his hot chocolate during the winter.
