Customer Ratings & Reviews

the cup works great, heats up quick, and keeps accurate temperature. Build materials are premium. The app doesn't connect all the time, even though is not required, unless you want to set the temperature to a new value.

Great product, excellent user interface, class looking! Only thing is, a little too small for practical use. Ended up returning to get the 14 oz.

Great product and a great Christmas gift or any Coffee or tea drinker. I wouldn't want to give this up now that I am used to hot coffee!

Great cup, bought it for my wife she uses it everyday

Wow!!! Just wow! every coffee drinker needs this. Amazing

Overall a nice purchase. I like the app but wish the temperature and battery life were on the same page. 145F temp is good for me, just right that it doesn’t burn. I keep the charger in my office and charge the mug overnight. In morning charge lasts 2-3 cups.

This mug has earned a spot on my work from home desk because of its set it and forget it and ease of use. The mug is on the smaller side with only 10oz but works as advertised. The max temperature the mug can maintain is 145 so if you like your drinks scalding hot this may not be the mug for you.

Easy to use , good quality exact what I needed in the mornings.

Product works well. Disappointed in the size of the cup

It’s a great mug.. everything good. The look .. . just size is a little small .. for the price ..

For all intents and purposes it does what it claims to do well, keep coffee warm. I had to dock it one star because it’s not a flawless device. The app is mediocre and it’s unclear at times what the temperature your mug is set to heat to without the app. That’s my #1 issue - the reliance on the app. Some physical tools to increase/decrease the temperature on the mug itself would make this perfect. The other issue I noticed is no matter what type of coffee I make - pour over, espresso, latte, drip - after I’m finished drinking there is a pile of fine crystals about the size of a dime at the bottom of my cup. If I drink the same drinks in a regular mug that never happens. I can only assume the heating element is causing them to form, and it wouldn’t be an issue if they weren’t so unpleasant to accidentally drink.

I have always loved hot coffee and continually putting it in the microwave was just annoying and wrong. I received this mug as a gift and will never drink from a regular mug again! I set it to my degree of warmth and it STAYS hot to the very last sip. And I can carry it wherever I go inside or outside. Absolute genius product! I would advise getting the 14 oz size to leave room for creamer and less spillage.

My wife bought me this mug for Christmas. I love it! My coffee constantly stays hot.

Great mug, works amazingly with the app to keep exactly the right temperature! Feels good and isn’t too heavy.

Something I’ve always wanted! My coffee stays hot even when I’m not in a hurry. Stays warm and fresh.

I am in meetings all day long and this ensures that I always have a warm cup of coffee or tea close at hand.

Have tried a couple of these for my wife (who is constantly microwaving her coffee keep it warm). This is the only one that has kept her from doing that - quality product (get what you pay for I guess - not cheap)

Very nice mom loved it and she says that she uses it daily

This cup is absolutely amazing! Its great!! Keeps my tea warm and tasty!

I bought this for my wife after she saw how much I enjoyed mine. I had bought mine a month earlier. These mugs are used several times a day and work perfectly. This mug did fail could not link to the app) and Ember replaced it for free even though it was 14 months old. The mugs are sturdy (coated stainless steel), I have dropped mine a few times, no issues to date. Very happy with the Ember mug.
