Works like it is advertized. Keeps the liquid hot for a long time

These mugs are great and do what they say they'll do. App is easy to use. Just make sure you don't leave it partially full, it'll keep working and the coffee with cook to the surface. Fortunately it's fairly easy to clean, but with the automated on/off, even if you turn it off, it seems to sense the liquid in there and turn itself back on. Just dump it out every time and you're good.

I would simply state it works as advertised. The mug keeps your liquid warm down to the last drop. The con for me is the price; a little steep for a mug. Even if it is a smart mug.

I was worried about the day I would eventually drop the mug and possibly watch it shatter. Well that day finally arrived, yesterday, dropping it directly onto my concrete driveway from about 3'. I saw it hit, expecting it to shatter, but it didn't! Still fully functioning with only a couple small scratches. I thought it was ceramic based but it appears to be metal, maybe aluminum, by looking at the scratches.

Liked that it keept coffee warm . More efficant battery would be great .

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

This mug is amazing! I love that my coffee stays hot without scorching it no matter how long I am distracted from it. My only thing is that the battery life could be better. But for me it's no problem as I have my charging coaster right where I sit in the morning.

When the package says to start at 135°, believe it. The cup and coaster are great for the work-at-homer, it’s not overly large and bulky. The cup has a nice weight to it but, is not to heavy when filled with liquid. Overall, I would purchase this again as a gift

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.

Got this as a present for my husband for Christmas. He loves how he can take his time drinking coffee and it will stay hot for a long time. Only thing is you must charge it every night.

I purchased the mug Feb 2022 for a Valentine’s Day present for my wife. She uses it every morning for her coffee and swears it has been the best thing ever! The only problem we have had with it is charging. You have to make sure it sits perfectly and wait for the flashing red to flash a couple of times. Besides that it still works just as well as the day we got it. If you take care of it and make sure it’s dry before setting on charger you will enjoy it!!!!

My parents love this cup. Keeps their tea warm for hours.

Love this!! Keeps my coffee hot all day long. Highly recommend

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!

This was a gift and she loved it. The cup keep the coffee warm to her temp. The phone app. is really simple to use. Great buy

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

Do you hate getting caught up with something, then you go take a sip of your coffee and it’s cold? That no longer happens to me. I LOVE my ember cup, keeps your coffee hot!! And it’s so cool, you get to choose your temperature and mess with the settings through the app to your liking for other beverages as well.

I like this one better than the regular ember mug which is around 10 oz. Honestly, if you work at an office or work from home, this is a must. Helps keep that coffee warm so you can be as productive and efficient as you need to be.

Pros: Mug - Sets and holds the temperature of hot liquids really well. I set my coffee for 126F (52c) and it's at a good drinking temperature without getting colder. Good for all day sipping. - The mug doesn't get too hot. It'll get warm but definitely no where what I would expect. - The handle feels nice and I can slip 3 fingers in there. The edge is sharp but definitely not something to worry about and adds a bit of class to the presentation. I like the handle. - The mug fits perfectly on the coaster so there's no guessing where it needs to be placed to charge.

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
