Customer Ratings & Reviews

Works amazing keeps coffee nice and hot. Fits in all my cup holders.

Does whst it says it will do. Perfect for desk jockeys who don’t want run to the microwave between meetings. This will keep your beverage at the optimal temp through call after call. I have an extra charger plate on each desk so i can move between rooms with ease. It is one of those things you don’t know you need until you have one! Worth every penny.

This is my third ember purchase. I have never been able to pair them with my apple phone but the standard temperature is fine. I have had trouble with the charging base and my previous one quit working in the second year.

Keeps coffee warm and makes it last so much longer

Bought this for a Christmas gift and returned it. Love the idea of keeping your coffee at a certain temp. But, like the old time glass coffee pots, they cooked your coffee giving it a burnt taste. Same here.

Get the best buy coverage, DO NOT rely on Ember customer service. They are the worst. Mug died after months, and I can't get them to help.

I bought this as a last minute gift for my son and another for my daughter-in-law. They just loved them. They work very well! They were very impressed!

Received the 14 ounce Ember mug as a gift. The battery goes from 100% charged to 5% in 10 minutes. It works great on the charger, but on Day 2 of use, I pull the mug from charging over night. The app says the battery is 100%. I make a cup of coffee from a Keurig pod, add cream, sit down on the couch, and within 10 minutes a message pops up saying its time to recharge. The Ember stops heating, and worse yet, the thin metal cup cools my coffee faster than a dumb mug! Again, it’s great when I sit at my desk with the cup resting on the charger, but never wander from the charger!

Great cup and design. Functions as advertised. However beware that the cup coating may begin peeling. Contacted Ember and is only warrated for 1 year. They sent a cup ONLY after a year that cost almost the same amount as a new set. It did NOT come with a charging plate. When it peels, i recommend buying another. I got a year in a half out of it before it started peeling.

Don’t waste your $ on this over hyped heated mug. Gimmick and nothing more. I’m glad I didn’t spend any $. I selected it for my 20th anniversary gift with employer. Honestly, I’ve been debating for quite awhile, but the high cost was always an issue. Battery life is ridiculous. I get 1 cup of coffee and battery life drops 7%. In fact, it drops 10% when removing it from the base after a full night of charging. It may be the app is not accurately reporting the correct battery levels? My only solution is charging between refills. As for the notifications? What notifications? I have them on but receive no notifications. Plus, device will sometimes not connect to the app and a reset is required including removing device from bluetooth. Disappointing to say the least.

Bought these as Christmas gifts for my employees. Everyone loves them. Great for slow coffee/tea drinkers

Purchased as a gift. Keeps coffee hot for almost three uses and only takes 2 hours to charge. Convenient to adjust the temperature from your phone. Will likely purchase the travel lid.

Product was great, worked as expected, customer service was awesome while picking up order.... 6 stars out of 5

I bought it in my trip to Walt Disney World, I’m from Argentina. It’s totally amazing!!! I love my ember mug!

I wish it came with a lid, luckily I had one that fits. I feel like it keeps my drinks warm for eaily 3-4 hrs

Keeps coffee at perfect temperature gor slow sipping. One charge will last enough time for approx 2 drinks.

the packaging was great and the products works well just wish i was able to make the temperature higher.

How can you justify spending so much on a mug? What’s wrong with us, are we brainwashed? Are we so lazy that we can’t even use the microwave to reheat our drinks anymore? We need help, we don’t need useless gadgets. The basic idea with this mug is outrageous. Battery holds power for about 45 minutes, I’m constantly recharging this thing, i have received it as a gift, it’s more of a gimmick

They make great gifts. I've bought several over the past year.

The first one we purchased holds the power so much longer than this one - not too happy that it drains quickly.
