Customer Ratings & Reviews

Love the mug. Keeps my coffee at temperature I set for as long as I need it to be. Easy to pair with phone. Also easy to clean after use

Nice size. Attractive. Works well. But it is yet another electronic and luxury device. It requires careful cleaning and handling (no dishwasher, avoid getting bottom wet), and electricity. It is not for everyone. There are other ways to prevent cold coffee. That said, I use it every day.

Easy to set up and keeps my coffee hot! Very slick color

Excellent piece of technology. I use mine everyday. The battery doesn’t last too long, maybe 2-3 hrs off the charger. But does what it needs to do and satisfying at that. Works well and very simple.

It's definitely not a necessity, and I wish it was a bit more reliable in terms of when it keeps my coffee hot and when it turns off. I'm figuring it out as I use it, and it's nice to come back after an hour or so and find my coffee nice and hot.

The Ember Mug is Easy to set up and program, keeps you hot beverage at whatever temp you set. Will last for 2.5 hours without charge. Need to electric for base to charge mug.

I am always complaining because my coffee gets cold before I can drink it. My new Ember mug has changed all of this. I customized my coffee’s temp and it suits me perfectly. Best investment and gift I have had for a long time. So happy with this product!

Keeps beverages warm. Easy app to use. Enjoyed it a lot.

Bought it for the wife she loves it wish it had better battery life..By the way when your charging it while drinking it won’t charge the battery it just keeps temperature..

The bigger size is the way to go. Keeps your coffee warm and easy to use.

This is our fourth ember mug in our collection and we use them daily. The battery lasts a decent amount and being able to set the exact temperature really puts the icing on the cake.

I love Ember mugs, especially the blue color! It keeps my coffee warm down to the last drop. I love that I can set the temperature to the level that I like. I definitely do not regret my purchase. Also, I was very impressed with how fast Best Buy delivered - next day!

Got it for the wife for mothers day. She loves her coffee crazy hot and this cup keeps out that way. Having trouble connecting on the app, but the cup still works

My wife loves to sit and have coffee before work but I’m constantly going downstairs to reheat but not with this mug . It’s incredible how it keeps her coffee a 140 degrees for so long and I ordered a cover which makes it last even longer . She loves her cup !!

Love this mug use it every day I would highly recommend

Overall it is a great mug, Seems like I had to keep it on the coast at all times to keep the battery going, I could only get an hour or something out of it. Also seemed like it took awhile to charge. If you can keep it on the charger most of the time you'll be okay. I also wish it was more durable. I have heard alot of people chipped theirs and I am trying not to do that, so I have to be careful with it.

Works really great to keep my coffee at exactly the temperature I want it. My one complaint is the battery life, as someone who can take longer to drink my coffee (i.e. why I wanted the mug), I have to be able to set it on the charger while I'm drinking it for it not to die before I'm finished.

This cup works great and greatly increases the pleasure of a hot cup of coffee.

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

Great cup. Works extremely well. It’s too bad the price keeps jumping around
