Customer Ratings & Reviews

I have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.

Great for one hour of hot coffee if not using the charging base. Most of the time this is more than sufficient. The downside is that after that hour, the mug requires 2 hours of time on the base to recharge. Ideally, it works better ON the base, but I don't have the room just yet (working on that).

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 put getting one of these off for awhile. That was time wasted. I have an entire cabinet of coffee mugs that have remained untouched for months.

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!

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.

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.

It’s amazing it keeps my coffee warm when not on charging plate and does the trick just walking around can sip on nice warm cup of joe all day

Works great! Was initially worried about some of the reviews mentioning difficulties using the app, but so far I’ve experienced no issues. Using the mug without the plate is still recommended though, as the coffee taste seems to alter very slightly after extensive use during a single sitting

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.

Given to me for Christmas- love it! No problems, heats up quick! No longer reheating my coffee several times! Love the blue! So unique!

Great mug, keep my coffee at just the right temperature for a long time. Awesome capacity.

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.

Love this mug and it does what it is supposed to. Just wish they had it in a larger size, my coffee disappears before I have a chance to really test the mugs heat consistency. It is really pricey though.

Great cup! Everything works well and is easy to use. My only complaint ( and it’s mine, not the manufacturer) is that the cup is too small! Should have bought the bigger one!!!

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.

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!

The Ember mug works well and I am very excited to have it. The only con is that I feel like you can't really turn it off, you just have to let it die (which doesn't take long).

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

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