Customer Ratings & Reviews

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.

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.

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 love my Ember mug! This is my 3rd one. I am hoping they can increase the battery life.

Great warmer my tea. Heat lasts long and has been reliable for years

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

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.

Best cup for the busy day. Get distracted...no reheating. Your drink stays hot.

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

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 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!

Love the blue color, the matte finish and the larger 14 oz size. Keeps my morning coffee perfectly hot which is the only way I like to drink it.

Did keep the coffee warm. The battery lasted about and hour before it needed to be recharged. Returned the mug because the ceramic coating started peeling off.

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

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

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.

Like this mug so much, I bought the travel mug and sent one as a gift. If you like your coffee to stay hot the whole time - it is great!

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

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.

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 !!
