- 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 February 3, 2025Color: WhiteSize: 10 ozVerified PurchaseThis product is quite impressive. While on the charger it will keep your beverage HOT all day. Off of the charger it keeps it HOT for 1 hr. While on the charger, it will heat up your beverage to HOT rather quickly. While off of the charger it takes way too long to do so. The product itself is amazing and I really recommend it for everyone who takes their time drinking and enjoying tea or coffee. I got this for my wife for Christmas because she constantly has to microwave her coffee because we have 5 children … but mainly because the 19 month old is demanding lol. I just regret getting a 10oz. I didn’t realize how tiny 10oz is because I assumed most mugs are 8oz. Wrong! lol. I am exchanging this for the 14oz. With the 10oz, once you put the coffee there’s hardly room for creamer and sugar (when it comes to a real coffee drinker). I gave it 5 stars because the product works excellently. The app is very impressive and fun (to me). I love to watch on the app how the T° of the coffee goes down immediately after pouring in creamer. I love it.
You can customize the color code of the light on the mug and name the mug in the app. You can also set the T° you want your beverage to be going forward (set it and forget it). It’s awesome. I watched a YouTube video about the mug and the review said they don’t think it’s worth the $ although the product worked really well. That’s kind of an oxymoron. I think you’re getting what you pay for and in a good way. Your beverage literally stays HOT or (if you want) warm until the very last drop. I don’t often drink coffee or even tea, but when I do it’s Dos Equis lol jk… when’s I do I can’t stand where the last few sips are cold. I want to get one for myself except I hardly drink tea or coffee, just to show you how great the product is. I think the 10oz is too tiny. 10oz might not be as necessary to be in the size of a tech mug since it’s not much to begin with and can be finished rather quickly (although my wife still appreciates it in her lifestyle). For the real tea and coffee drinkers out there I highly recommend this product, but the largest versions.
- 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.

- Scott MarshallReviewed in Australia on December 3, 2024
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.
