Customer Ratings & Reviews

The mug does exactly as advertised. I get about 1.25 hrs of usage out of this using the max temperature ( I like it uncomfortably hot). App has connectivity issues but can be fixed in future updates.

I like it. It keeps my coffee, warm and cold weather.

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

I've only had this mug for three weeks, but so far it works really well. Better than I expected. We'll see how long it lasts. I like that the cup recharges very quickly. The app to control the temperature seems to be easy enough to use. I only gave it four stars because I don't know yet how long it is going to keep working. So far though, it's been really great.

 This mug is the Cadillac of heated mugs if you add the lid, it’s the best of the best doubles the time your coffee will stay piping hot when you put the lid on and you sip out of it it’s smooth sailing not like other mugs where you gulping simply the best. Add in that you can run it all from your smart phone on your iPad and customize everything. Wow, happy happy 

Bought as a gift for girlfriend because she likes her coffee super hot. This goes up to 160 degrees (i think). The battery does not last long on the highest setting, so you always have to put on the charging base while using.

It’s perfect for the morning cup of coffee. It keeps my coffee warm up to 30 minutes.,

I have been using one of these terrific mugs at home for over a year. Once you have had one it is difficult to live without, hence this new one for the office. This ingenious product delivers exactly as promised keeping your tea or coffee at exactly the preselected temperature for over an hour off the base and indefinitely on the base. I thoroughly recommend it.

Boxes for my daughter because he makes her coffee and then she gets doing stuff and then her coffee she dumps it out she's only had two sips out of it now she can finish her coffee keeps it hot

I have been wanting this mug for a year but didn’t love the price. My husband surprised me with it and I was over the moon. I love the sleek design and the app. I will say the charge on the mug doesn’t hold that long (for someone who needs a mug like this, it’s because you get busy and don’t have time to drink when hot) The biggest issue is that because I use a little milk in my coffee the cup essentially cooks the coffee whole time which led to a skin of coffee/milk forming on the top. I returned it.

Great product and love the temp control! Only wish it was a little bit bigger. 20oz maybe? Otherwise great product!

Love this mug. Keeps my coffee hot for hours even if I forget to drink it right away. Easy to clean.

I love that it keeps the coffee at the perfect temperature for me. The battery won’t last more than 50 minutes off the charger, but I usually drink it with the charger nearby so that’s fine. My only ding is that the charging pins stick after a while and it struggles to maintain a connection to properly charge

Really surprised at this Heated mug. My wife has been asking for one for a few gift occasions, and I always thought they were silly. Well I got her one for Christmas finally - and she loves it! She uses it all the time- it’s the only mug she uses at the house (still uses travel mugs). But these are so cool that I’m convinced and want one for myself. I’m going from thinking they were silly to asking for one for my birthday!!! Would expect others would be sold like me. A great gift idea as it may not be something someone would splurge on for themselves

As most of us know, coffee is much more effective when it’s hot,  I work from home, and throughout the day, I used to put my coffee in the microwave 5 to 10 times a day and that ended when i got this smart coffee mug that allows me to set my preferred coffee temperature through the app on my phone. And it notifies me when that set temp is reached. The app works great, seamlessly connects with my phone with instantly. Its a game changer in my coffee life.

I bought 2 of these, one for my mom and one for my mother in law and they both adore them. It’s a great way to keep coffee hot, and super easy to use. Perfect gift for the hot coffee lover in your life.

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.

My wife loves it. She's a sipper, I'm a gulper. Her coffee has been hot all morning. She even takes it down to the bus stop and folks ask her how her coffee is still steaming when its freezing out!! So, yeah, she loves it. I clearly haven't been able to try it yet, because SHE LOVES IT SO MUCH. It took a few tries to learn the right temp settings to keep her Nespresso from getting a film, but she's found it and there is no turning back. (Might be a little pricey, but got it on sale and her smile is worth it)

It does work, but it’s not something that will stay charged long enough to use all day.

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!
