Best bug, holds the charge really well. Minor flaw is: Bluetooth disconnects frequently

Pick the temperature that you want your coffee to be, and it will always be it! No more cups of cold coffee

We have bought different ones but they alway disappoint, unlike this one my husband is really enjoying it.

Wife loves it!!! With a 1 1/2 and 3 1/2 year olds running around all morning coffee tended to get cold and microwaved but with her new Christmas gift cold coffee is a thing of the past

My wife is really enjoying her hot beverages. Mug exceeded expectations.

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

Like this mug so much, I bought the travel mug and sent one as a gift. If you like your coffee to stay hot the whole time - it is great!

My wife loves it especially because she set it to the temperature she takes her coffee and stays hot while she is busy

I love this cup, my drinks stay at whatever temperature I set for the entire cup down to the last drop!!! This is an excellent gift idea for anyone.

App for the cellphone has been updated from the original app that I got a couple of years ago. The new app works much better in regulating the mugs. This my second mug because I liked how well the first mug worked. Both mugs are working great.

I Purchased this item because I’m on zoom all day and drink a lot of coffee. I would make a carafe and microwave each mug full to make it hot before drinking- reheating often if I didn’t drink it fast enough and it got cold. I thought this mug would be the PERFECT solution. Here’s why it wasn’t: 1- I always started with hot coffee (pour over coffee) brewed directly into the cup. Although it kept the coffee at the desired temperature, the mug lasted an average of 45-50 minutes when it was advertised to last about 2 hrs. My average meeting is 90 minutes. 2-the mug took too long to recharge, so I took to keep it in the base (plugged in) whenever I wasn’t drinking. Even though I took sips often, it would still go into ‘sleep’ mode, the coffee would get cold and I’d have to restart the mug again and wait several minutes for it to get hot. 3- sometimes it wouldn’t restart… and I’d have to exit zoom to look at the app, which would show “empty” even though the cup was more than 1/2 full. So I guess it’s not good for continuous use. It did these things so often, I returned it. So I'm back to nuking my coffee when it gets cold. It’s a hassle but it works… and it doesn’t cost $120!

My wife and I always fight the temperature of our coffee in the mornings. We no longer have to do that when getting distracted with the kids and their activities. All I have to do is place it on the charger and come back hours later to a perfectly hot cup of coffee... It's so awesome! Be sure to blow out the bottom since water likes to hide in the grooves (it's waterproof but just to be sure).

Keeps hot drinks the perfect temp, works great for coffee and tea. Easy to keep clean and use.

I love drinking hot coffee, and this mug made it perfect to drink hot coffee and teas. I don't drink coffee too fast, and regular mug cools it down fast before I even get to finish the coffee. However, this cup made a huge difference. It's easy to setup and use!

Keeps coffee hot! Wish it would last just a little longer and was a little less expensive.

Good cup. Working without any issues for the last year

Serious Quality & Safety Concerns – Disappointed with Ember Mug I purchased an Ember Mug and treated it with great care, but was very disappointed to find that the interior coating began chipping and flaking off over time. This raises serious concerns for me about potential toxin exposure, as I may have unknowingly ingested harmful materials. I reached out to the company with hopes of a responsible resolution—specifically requesting a replacement mug made of stainless steel or another safer, more durable material. Instead, I was offered only $32 toward the purchase of another expensive mug that could very well chip again. This response felt inadequate and dismissive, especially given the potential health risks. TOXIN ALERT – I urge others to think twice before purchasing an Ember Mug until these issues are properly addressed. Product safety and customer health should be the top priority.

Works great and very easy to use. Wish battery wouls last longer.

I was reluctant to buy this mug. I have been looking into getting one for a few years. Once the 14 oz version came out I was even more interested. So far the Ember meets and exceeds my expectations. It is great to have a hot cup of coffee all the way to the last drop. It was even a little weird to not have to drink cold coffee on my last sip. I have only had this mug for a short time but I am very pleased.

My Mother-In-Law is still thanking me for this super amazing coffee cup!
