Customer Ratings & Reviews

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

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.

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

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!

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.

Works wonderfully and keeps temperature . Love how you can sync it to your phone and have it set at a certain time of day and your beverage be ready for when you're ready to be on the go.

It’s perfect for the morning cup of coffee. It keeps my coffee warm up to 30 minutes.,

I love this cup, my drinks stay at whatever temperature I set for the entire cup down to the last drop!!! This is an excellent gift idea for anyone.

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.

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..

Love this mug. Keeps my coffee hot for hours even if I forget to drink it right away. Easy to clean.

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

Use the app to control the temperature. Easy to use

Wife loves it!!! With a 1 1/2 and 3 1/2 year olds running around all morning coffee tended to get cold and microwaved but with her new Christmas gift cold coffee is a thing of the past

Keeps beverages hot! Easy charging, easy controls.

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

Bought this as a holiday present for my husband and he uses it everyday. It’s been over a year and he still loves it!

Love this cup! However, I had to purchase an additional charger to keep at work. The battery life is ok if you are a 1-2 cup coffee drinker. Which I am, before I even get on the road to work but by the time I get to work my coffee is cold. After I purchased the additional charger, I would say this cup is a game changer.

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.

I bought this as a Fathers Day present for my husband after he was going back and forth about getting himself one. He was initially skeptical. However, he has come around and uses it every day. We’re even considering buying the travel mug version as well!
