Wish it could be bigger . Works well and really keeps your drink warm .

Temerature control works very well and thw app is very easy to use.

Keeps temperature Perfect, very nice and feels solid

I got this mug for my lawyer friend! She always has to chug her coffee before it gets too cold and she has been loving it! She accidentally forgot it was heated up and after an hour she took a sip ad burned her tongue the mug worked so well. Def recommend for hot coffee even hours after you pour the first cup

I really like this cup. It is easy to operate and I no longer have to drink cold tea. I like that I can change the settings from my phone.

While it’s great to have your coffee never get cold, the max temp by design is 145 deg. Not hot enough for my palette. I’d imagine it’s avoiding some litigation? And be prepared to keep the mug on its stand as the battery dies quickly, probably due to the fact that I have the highest temp selected. Still I no longer have to microwave my coffee to warm it up. If it went several degrees hotter, 4 stars. Would still recommend despite the shortcomings

Keeps my coffee warm, love it. Great size too, normal size cup of coffee, easy to use. Great for working from home next to my desk.

Love the color, and the metal finish seems more durable than the old white plastic (my old white one is all scratched up on the inside from spoons).

It’s great for morning coffee! It keeps it at the perfect temperature for me. I love it!

Price is steep but works well. It's stylish and keeps coffee warm. I wish it was a few oz larger.

Perfect size, keeps drinks at a nice temp. Different temps for different drinks. Mug battery life is ok but it you're a really slow drinker may not last.

It's been used every day, great at keeping your coffee warm or even hot if you like. Battery doesn't last whole day but good enough for the cup size

I have had this mug for almost 2 years and have gifted to friends and family. Best invention ever! I love how pretty the copper is as well as how well the product works!

This is a MUST for every HOT tea/coffee drinker! It's a perfect office gift.

I love HOT coffee through the last cup and this makes that happen, does not "cook" the coffee and app gives me ability to adjust. Handle is perfect, and rim is not thick so that is perfect too........only thing is that is hold a cup size not a mug size of quantity, but for my expresso maker its perfect.

Wife LOVES this mug. She was reheating her coffee 3+ times before finishing a single cup. No more. Works perfectly. She did experience an issue after 7 months of use; customer service was great and handled the situation in a way that exceeded expectations. I bought three more as gifts for friends and family since.

I heard about this mug years ago and laughed it off. There was sale so I purchased lol, I use my Ember Smart Mug daily! The app is easy to use. The mug keeps liquids hot. I have put cold liquid and it heats up to 135 degrees. I wish the larger 14 oz. was available for purchase. I originally ordered gold but exchange for copper but both look great.

As the owner of both the black original and now the stainless steel version, the latter is my clear favorite. It does the same thing as the black, but it looks cooler doing it.

Love the mug, keeps it nice and warm at the temperature I want. Love that it it’s pretty big since I do drink plenty of coffee in the morning. Mug actually has stopped working couple days ago and I’ve had it for 4 months, contacted Ember they will be sending out another mug since it just completely stopped working, doesn’t light up or anything. But other than that works great, keeps it super hot if I put it on highest which I love since I look forward to my coffee and I work from home so I spend all morning drinking it. Love the purchase.

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