Customer Ratings & Reviews

I would not consider living a life without this thing. We drink coffee every morning and drink tea once per week. You know how it sucks when hot beverages start to go cold? Welp for $150 you never have to experience that again!

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 !!

My wife has a home office set up with a mini fridge and coffee maker, and when she’s home working, she spends hours on video conferences, and when I happened to drop in on her, I noticed her coffee was often left sitting on her desk partially full. I know she likes hot coffee so I surprised her with this so her coffee will always be hot, and she is thrilled with the results, saying she never realized how much she missed having a hot cup of coffee during the day.

Works great. A bit pricey but it was a gift. Keeps coffee hot!

Ember works well. Maintains a consistent temperature. Only complaint would be regarding the length of time the cup is able to do so.

My parents love this cup. Keeps their tea warm for hours.

This is the second ember mug I've owned. I had to get a larger one because I enjoyed it so much. Get him when they're on sale. Novel product but thoroughly enjoy it.

I got this mug for my wife for Christmas and she loves it! The app works well and it keeps her coffee nice and hot all day long. It's easy to clean and very solid. Great buy!

Always keeps my cup to the perfect temp. App is easy to use and simple simple sjmlle. Highly recommend.0

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

Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

Great cup, it has a few quirks about charging and knowing when to charge it. The app has a few issues though.

It is the best at keeping your coffee hot without have a lid. Works great. It’s expensive but after using it on a cold morning it’s worth it

I like how this keeps my coffee or tea at a nice warm temperature for a long time. This is the second one I've had. It's been a good purchase.

If you love coffee, you need one of these! It is fantastic! By far the best gift I've ever had. It surprised me how much I love this new cup. Not only does my coffee not get cold as I move around the house, even when I'm using it at my desk keeping it on the charger, this cup let's me enjoy that cup even more. All the typical changes in temperature you don't even realize you've gotten used to in a cup of coffee are just gone. I promise you'll love it.

So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

Easy to hold, maintains perfect temperature for 3 hours with the Ember lid accessory.

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

Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

I've wanted to get my husband an Ember mug, but he thought it was too expensive. It IS a lot for a coffee mug, but he is really enjoying the fact that his coffee isn't continually getting cold before he can finish it. We've gifted four family members with Ember mugs over the past two years, and each one of them loves to use theirs.
