Customer Ratings & Reviews

I like the concept of this mug. Overall it has worked well, 9/10 times getting it right that there is a beverage in my cup. My I main complaint is thst i feel tied to the charger. 80 minutes goes by faster than you’s think.

Expensive, let me say that first. If BB did not have it on sale I would have passed on it but it does keep my coffee hot! The mobile app is a great plus as well to control the temp settings. Easy to charge, easy to rinse, and clean for the next use! Not throwing it in the dishwasher for sure!

I’ve read about the Ember mug for a while now. It went on sale and I thought I would try it out! I love it!!! Bought one for my wife as well! I get to enjoy my coffee while it stays hot the entire time. No more warming my coffee in the microwave. The app is great too. Tells me the temperature and how much the battery is charged. I recommend it!!!

I am so please with this mug. I thought it would be similar to the electric cup warmers but so much better. I work from home and at times get distracted, when I return to my coffee, it’s cold. Not this one, it remains at temperature I set. If I have to run out I can carry and it’s the same temp as I set. Saves from wasting coffee throughout the day because I let it get cold.

Love these mugs. I am spoiled by them now, it's so great having my tea at the perfect temperature all the time. Unfortunately, they are finicky and the charging coaster stops working after a while. Still worth it to me.

Some say, $130 for a coffee cup?!!!!! I just say, YUP! and it is worth every penny! I use this cup almost every day. If you are a coffee drinker or really any hot beverage drinker, you can take your time and savor it without the worry of picking it up absentmindedly and taking a big swig of luke warm or worse, cold liquid. Your 100th sip is as hot as your first. And if you are like me, absentminded at times, when you brew your cup and forget you did so until you happen to walk by it 30min later it isn't a big deal. It was sitting there waiting for you as hot as it came out of the brewer.

A nice mug, but battery life can be an issue. For me, it heats my coffee for about an hour, but for anything more than that it'l run out of battery leaving you with a cold beverage. Not the end of the world, but as long as you work within this limitation it's a fun product. Need to be careful when washing, so that you don't get a lot of water into the underside (where the battery is housed).

I purchased this as a Deal of the Day at a reasonable price. It does take time to get use to it. I'm satisfied with this Ember Smart Mug. I just needed something to keep my Lattes warmer a little longer. I like the 14oz size so there's room to stir without splashing it all over.

Love the mug, definitely keeps coffee hot. Not sure if my coffee maker is off or if this mug doesn’t actually hold 14oz. If I brew a 12oz cup it’s at the brim. Had it for a month and a half now with zero issues

I bought this cup for my wife. She likes to take her time drinking her coffee and latte. She would usually have to microwave her cup two or three times to keep it hot. This cup does the trick! Keeps her coffee nice and hot, 145*, for hours! You can adjust the target temp to your preference but it tops out at 145. Great cup and has held up perfectly since purchase almost 6 months ago.

This product is amazing! I no longer have to worry about my coffee going cold even after hours of schoolwork, my coffee is as hot as when i first brewed it. I will say that the only downside is the Embers app, but to me its not that big of a deal because i can use the mug without the app.

I adore hot beverages (coffee, latte’s, expresso, teas, coco...) but I don’t like that they generally don’t keep their heat for very long. My mom “especially” doesn’t like anything that’s not very hot! She makes a new cup of coffee, and before even drinking it, puts it the microwave oven to heat it even more. I bought one of these mugs awhile ago to see if it was a solid item. Found out that it was, even better they came out with a second generation version which stays hot even longer! I picked one up for my mom and while hesitant to accept it, truly adores it! As a side note, it’s has a great software addition (no extra cost) that allows you to select a specific temperature and manage its power usage! My heartfelt recommendation is to try this out... if you don’t like it, no problem as Best Buy has a great return policy. I’m confident that like me you’ll adore it. Happy shopping...

I never thought I needed this kind of mug. But it is amazing! Side tracked and forgot about your coffee? No problem. This mug keeps it warm and fresh, as though you just poured it. Easy to clean and love the color.

Like the title states, it is expensive for what it does, but it does what it is supposed to do well. App is easy to to use and the mug holds a charge well. Only cons is price, and isnt dishwasher safe.

Bought as a Christmas gift for my wife, she loves being to keep her coffee warm in the mornings. Only downside is they should include from the factory a lid for it to extend battery life and help with spills.

Okay was it a splurge? Yes! But honestly the amount of coffee I was wasting makes this thing worth every penny. I can walk away take a call or jump on a zoom and my coffee is still piping hot when I return. Love that I can adjust the temp for tea or hot cocoa if I want it slightly warm

In general wonderful! I sit at a desk for long periods and this will keep coffee hot for well over an hour. The only problem, is that its almost too hot. I know there is supposed to be a way to control temp on the app...I'll have to look into that. The button on the bottom is a bit touchy but it works.

This was a present for my husband. He like it very much as it keeps his coffee hot throughout even a long meal. It’s convenient and we even take it to restaurants to be guaranteed that the beverage stays hot. However, it’s quite costly and it’s strange that different colors have different, often higher, prices.

These mugs may seem like an extravagance - but when you experience access to hot coffee thirty minutes after you filled it.. you can't avoid a comforting smile! We bought two of them - one of them has less battery life. I doubt the battery is replacable.

Got this on sale for $99 and it was very nice. Great construction however if you are a huge back-to-back coffee drinker, you may want to consider that the battery life is about 80 minutes and you may want to purchase multiple bases/lids for it. Great concept though! Wish the battery was a little bit longer, but for how light the cup is, I can’t complain.
