Customer Ratings & Reviews

Christmas present for wife. She already has one; this is a “travel” mug. She LOVES always-hot coffee. Genius invention. Once you have an Ember mug, you’ll never want to drink coffee in anything else.

Wanna win some brownie points? If you or your wife drink coffee (other other hot beverages) this is the way to go. Wife loves the 10 oz. mug, she REALLY likes the 14 oz. and the extra time it keeps stuff hot!

Controlled by my iPhone. I don't like lukewarm tea. This cup does what it says and honestly keeps my tea at 142 degrees to the last drop. I keep filling it during the day with tea from a thermos and it heats it up within a few minutes. Expensive - yes - but it's been worth every penny for me to enjoy hot tea every day.

Amazing!!! It keeps my coffee warm as expected and I don’t have to use the microwave for this anymore

These cups are amazing, we have 3 of them, keeps your coffee or tea warm up to an hour.

If you like hot coffee then Ember is the way to keep it hot. Totally recommend this product.

Got this for my wife who constantly has to heat up her morning beverage throughout the morning and hasn't had to do that since getting this mug. App is easy to use and she loves the special edition blue from BB.

What's there to say? I have several Ember cups. All perform exceedingly well. This is my newest. It's an exclusive blue color. I believe this is a Bestbuy only model. So, yeah, It's a no brainer. You get a one-of-a-kind color of an excellent item. So get it already.

I purchased this mug for my techy bf's birthday. He LOVED it! I tried it later and loved it too. Long story short, we have 4 of these mugs now for home and our offices. Just make sure you hand wash it, and put it back on charger once it's completely dry. Also, don't use a metal spoon. We got silicon spoons to protect the mug.

I LOVE MY MUG! Never another cup of hot coffee! I have the white model and it did stain a bit in the bottom, but I love the way it functions and I can select my temperature from the app. Excellent product.

The cup doesn’t get hot but your drink stays the temperature you like it to be. The simple functions it provides versus a warmer plate.

It does work, but it’s not something that will stay charged long enough to use all day.

Bought this for my wife as I’m not a coffee or tea drinker. She likes it but the battery life doesn’t last long at all. I think it’s rated at 80 minutes and that might be on a good day. She just moved the base to her desk and it pretty much stays on there all the time.

No more cold coffee!! Yay! Battery lasts about 90 minutes, which usually gets me through 3 cups full while working! Perfect for me!

Love it and use it several times a day. (8am-9pm). The reason I gave it 4 stars; The app could be better, the light on the cup could be more intuitive, and battery life could be better (1.5 hrs without charging).

Doesn't connect all the time and have to keep resetting it but when it does connect it works great.

Excellent smart mug. Works really great to keep my coffee warm at the perfect temperature at my desk. The only reason I did not give it a 5 star is because the battery life could be a little better. I did get around that by plugging in the coaster on my desk.

Bought this mug for my husband. He loves it! His only compliant is it doesn't hold a charge long. Which is why I rated it at 4 stars.

Elegant design works as advertised. Easy to program temperature. This is our 3rd mug.

I purchased for my wife as a Christmas gift...she loves th tech stuff. Was a big hit! Loved the ability to set colors on the LED, as much as how well it keeps her drinks hot. She's still talking about it!
