Customer Ratings & Reviews

I brought this for Christmas for my coworker/friend. She drinks tea throughout our whole shift. Our office area is constantly cool where she has to repeatedly rewarm her tea. I thought this would make the perfect gift. She uses it daily and love that her drink stays at the temp she like. Additional bonus is it works with an app on her phone.

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 !!

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

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

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.

Very good product and works great, easy to use and worth the money for any one who would like to enjoy their drink for a longer time, or someone who has a lot of multitasking

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.

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.

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

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

Decent cup. Works as advertised. Battery depletes fast when in use however.

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!

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

My wife loves this. She always takes forever to drink her coffee or tea so I got her this so it never gets cold or lets her beverage go to waste.

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.

I really like the cup. However, unless you purchase the lid that goes with it, you’re gonna constantly have a film on top of your coffee. Also, the cup doesn’t stay fully charged even when on the charger maybe 80%. but most importantly, it keeps my coffee, hot all day.

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

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.
