So great to sit coffee, tea or whatever slowly and last sip as hot as first!

This was given to me as an Xmas gift. I've successfully been able to use this with the app three times since December. There are consistent issues with connectivity between my Galaxy S20 and the app. The app will say the mug is charging, but hours will go by and it's still at the original percentage. When it has worked this thick film of burnt coffee accumulates around the rim. I'll be busy working grab the cup for a sip and it leaves the worst taste on my mouth and lips. Do yourself a favor and use the microwave if your drink gets cold.

Love it, just wish it stayed charged longer. Very happy otherwise.

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.

Keeps coffee warm and makes it last so much longer

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.

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.

Ive had these over the years when they first cane out. Every single one has stopped working after about a year. Ive tried to contact ember but they only offer a discount for a new one. I wish they would offer a longer warranty because the battery dies after a year.

Cup quite working a few months after having it a year. It charges and turns on but doesn't recognize any liquid you put into the cup. All ember wants to do is give you $22 off on a cup and it not come with the charger. Also took them over a week to get back. Truly upsetting

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.

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.

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.

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

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

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.

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