- Reviewed in the United States on June 5, 2025Color: BlackSize: 14 ozVerified PurchaseMy bf was incessantly complaining about cold coffee. Our poor microwave got a good workout on warm-ups and it was inconvenient when we were upstairs enjoying weekend whatever's and it was downstairs. THIS is a great solution for situations like the one I just described. I saw earlier models of this concept and the reviews weren't great, so I revisited it later knowing his birthday was coming up and knowing if I heard one more complaint about it I was going to lose my marbles. That is never good for our house when THAT happens. So, I took the plunge and it was a good call. I haven't heard a stinking squeak about cold coffee since, and it sure has been nice. Now, if we can work on the slurping when he drinks his coffee it would be perfection but we pick our battles, right? I'll take the quiet for now, Lol. Ladies, if you are a middle aged peri- menopausal woman like me who has little patience anymore for unnecessary difficulty and values low blood pressure and easy everything, this just might be your ticket to a peaceful, weekend heaven. Hot coffee and a happy boyfriend equal quiet weekend mornings for me so it was worth every penny and then some. Winning!
Side note: I waited to write this review to make sure there were no product flaws. There are none to report. Seriously, not a single one, and this guy drinks multiple cups of coffee a day. We bought this unit in January. It's been working consistently great, zero issues. We highly recommend. You're welcome!!
- Reviewed in the United States on June 21, 2025Color: BlackSize: 10 ozVerified PurchaseFor 50 years, as a mother, I had never had a cup of coffee or tea that was still hot at the last sip. That's what happens when you're a mother. I just got used to it. Then my DIL got me one for Christmas. Talk about a life changer! OMG! It is so wonderful to put my cup down to do something and come back to my cup and it's still the perfect temp.
Well, I let my husband try my cup out, and ended up getting him one for his birthday because he never finished an entire cup of coffee because he hates cold coffee. What a waste of coffee and money! Now, we both enjoy our beverages at the perfect temp, all the time. And no more wasted coffee.
- Reviewed in the United States on June 9, 2025Color: BlackSize: 14 ozVerified PurchaseOwning this is how I know I don't have any real problems in my life. I always thought flying cars would be the key indicator, but this item proves that we are now living in the future. Coffee stays as hot as I want it; I don't have to finish it more quickly than I'd like to, or settle for less-than ideal drinking temperature.
I will note two minor drawbacks which may impact you more than me, depending on your use case. First, I'm anxious to place the mug on the charging station until I know it's thoroughly dry, but since I only use it on leisurely mornings, not every day, this is no problem. Second, it can form a "skin" over coffee if I use too much milk or cream (which would be too much, anyway). But neither of these issues have managed to ruin the experience for me.
- Reviewed in the United States on May 29, 2022Color: BlackSize: 14 ozVerified PurchaseThe original review was accurate, but now that I've had the mug for 6 months (Originally 3 star), I have to reduce its rating... The mug itself is great, works well, and does what it says. It keeps my drinks at the temperature I set it to. The reason I'm reducing the rating here for 2 reasons.
1) Trying to reach an actual person or something more intelligent than an automated help desk, is seeming to be nearly impossible.
- To expand on this: I have been unable to find any contact information to report any issues I do have with the mug or software (I have no issues with the mug so far, but the software annoys me to no end).
2) The software for the mug is so far below par, that they might as well just have a digital display on the side to show the temp and just set it that way.
- Let me expand on this:
a) If you don't keep your mug paired, ie: carry it with you 100% of the time, anytime it isn't paired, it forgets its pairing, and you have to go through the pairing procedure again to reconnect it. My car is a 2014, and the BlueTooth in it remembers my phone when I start it up, but this mug cannot.
b) There's no way to override the heating to ON, if the sensor doesn't trigger to say the mug isn't empty, it won't turn on, even in the software Bluetooth connection. Through some digging, it states that it determines if it's empty by the significant difference in temperature: The mug is cold, pour warm to hot fluid in it, and it detects the temp change and determines it's not empty. I understand this is probably a safety feature to prevent the mug from burning out, but there should be some way to turn it on when you put room temp liquid into a room temp mug. (I usually make a batch of tea, and if I don't finish it all in a day, I use it the next day, I shouldn't have to microwave the first cup just to get it hot enough for the mug to realize it's full.)
So in summary:
-The mug is absolutely great, so far it's held up fine, with no chips/scratches. Works great to keep temp set.
-Software needs a LOT of work. The biggest issue is the Bluetooth connection/protocol. I shouldn't have to re-pair it every day just to connect to the mug to change it from Tea to coffee, or some other temp for a different drink.
-Better contact forms, for when you can't resolve the problem via automated help.
I'm hoping that by rating this at only 1 star, maybe I'll get a way to contact the company, or at least they'll read this review and take the issues under advisement. Maybe even make a suggestions/complaints form to get these issues noticed so they know what to work on. Until I see a way to contact a live person, even if it's just email, or something simple, I cannot rate this higher than a 1. IF I were having a real issue with this mug (like it not working) I'd be out the money it cost me to buy it.
Original Review Below this line:
***********************************
Keeps my tea at the temperature I set, making every sip enjoyable.
Pros:
Heats relatively fast
Keeps Temp very well.
Con's:
It's for Right Handers, if you're left-handed, (or hold the mug in your left hand), the LED is on the back side where you can't see it (less of a problem while you're actually holding it), but if you set it down for grabbing with your left hand you can't see the LED.
The software is a little glitchy. I tried setting it to Celsius for a little bit, then when I tried to switch it back to Fahrenheit, it wouldn't switch, I had to reset the app completely to default to get it back to Fahrenheit.
Couldn't find a contact form for issues (like the above software glitch), or suggestions.
- Reviewed in the United States on June 19, 2025Color: CopperSize: 10 ozVerified PurchaseI have bought this mug two times as a gift and both recipients love it. It's super easy to set-up and use and it keeps your coffee/tea very hot (sometimes too hot!). I like that it has temperature control, so you can raise and lower the constant temperature of your beverage to fit your liking. I plan on buying one for my work office, since I am always interrupted and never get to finish a hot coffee! Definitely would recommend for any coffee lover or for anyone looking for a unique/quality gift idea.

2.0 out of 5 stars 6 cups down and it the WORST
Color: WhiteSize: 14 ozVerified PurchaseEmber cups are a fantastic concept and incredibly useful, but I’ve encountered some challenges with the company's aftercare service. It's frustrating that I've had to rely on Amazon for repeated replacements of my cups. For users who utilize them often, it can become a hassle to request repairs or full replacements regularly.
It’s disappointing, especially considering the investment. I hope the company can improve their customer support to match the quality of their product!

3.0 out of 5 stars Great for coffee lover, not so great for tea lovers
Color: WhiteSize: 10 ozVerified PurchaseThe Ember Smart Mug 2 can keep your tea/coffee at the perfect temperature for hours, making every sip as good as the first. However if you like very very hot tea then this product is not for you. Because usually we like tea to be very hot. In short it does not give you a boiling hot tea. just enough to keep it not cold.
