    Definitely a smart mug

    Posted .

    I received this mug as a gift, and it's perfect. I paired it with the app, which can be a little glitchy, but not a complete waste. You can control how hot you want you coffee, up to 145 degrees. Also, if you share your mug, or have the same color, you can customize the LED color to identify who the cups belongs to. You cannot microwave your cup, but honestly, I have poured in cold creamer and waited for my coffee to get hot just to experiment. It's neat. And if you pair the mug with the app, you can choose which temperature to maintain your coffee. I charge the cup after using it, and will simply take the cup with me to my home office for a few hours. Battery life away from the base depends on the maintained temperature. Overall, I love this mug, because it's not your typical mug plate where you have to keep the mug on the base. You can also wash the mug, but not keep it submerged in water, I recommended immediately washing it, or if you don't have time, fill with regular water to soak, turn off the base, and clean it later. Again, just don't submerge it or it will ruin your cup. All this is in the nifty packaging it comes with! I would recommend as a gift, buying it for yourself or to impress your guests.

    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.

    Multiple benefits and conveniences - pricy

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    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.

    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.

    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.

    Keeps Coffee Warm!

    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.

    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.

    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.

    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.

    Too small, short battery life

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I received this mug as a gift. The mug is 10oz which is too small for me and makes me choose a smaller size on my keurig if i want to add creamer. The mug dies very quickly unless you leave it on the charger. It doesn't usually even last for 1 cup of coffee for me. The heating causes my coffee (with cream) to build up a gross film on the sides of the mug

    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.
