Wife loves it!!! With a 1 1/2 and 3 1/2 year olds running around all morning coffee tended to get cold and microwaved but with her new Christmas gift cold coffee is a thing of the past

Keeps my coffee piping hot all day. Note, the rechargeable battery is not replaceable and lasts around 2 years, then the whole thing is trash. That's why 4 stars instead of 5.

I love that it keeps the coffee at the perfect temperature for me. The battery won’t last more than 50 minutes off the charger, but I usually drink it with the charger nearby so that’s fine. My only ding is that the charging pins stick after a while and it struggles to maintain a connection to properly charge

I was always on the fence about getting this mug but after getting one I do not regret it. There are plenty of times I was unable to finish my morning latte and I would just end up drinking it cold or like warm. But after getting this mug I can now enjoy it warm all the way until the end.

Love the color! So nice and smooth to touch. Keeps my te hot. Great to have at home and at the office. Have to get one for my husband too!

Keeps my drink warm. Few quirks with the 1 hour battery life. White color also has coffee stains and burner stains at the bottom. Still works great after 6 months.

Love this cup Sometimes the charger has worn out but they sell replacement chargers. Only drink my coffee with that mig

My wife loves this. She always takes forever to drink her coffee or tea so I got her this so it never gets cold or lets her beverage go to waste.

My wife’s loves this mug. It would be great if the battery lasted a little longer but fixed that by adding another base in the house. It’s great that anytime you go to get a drink of coffee it’s the right temp!

I bought the 14oz mug and I must say it does exactly what it is supposed to do, and does it great. I was using a mug wormer that you place a regular mug on and it just wasn't doing the job well, so the Ember mug really solves that. Also, they claim the battery lasts 80 minutes, but I am able to get closer to 1.75 - 2 hours. My only real comments are that I am left handed and because the status light is only on one side, I can't see it without turning the mug around. I also wish it was 16 oz since my Jura puts out 14 oz of coffee and I have no room for creamer.

Wife makes the best use of it always having her warm coffee

Was surprised that I drink less coffee. No dumping cold coffee anymore. A little $$$ but still pleasantly pleased

This is an amazing way to keep your coffee from getting too cold. I love the fact that I can pour a cup of coffee and sip it for much longer than a regular mug. It has a nice sleek design too!

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!

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.

A nice mug, but battery life can be an issue. For me, it heats my coffee for about an hour, but for anything more than that it'l run out of battery leaving you with a cold beverage. Not the end of the world, but as long as you work within this limitation it's a fun product. Need to be careful when washing, so that you don't get a lot of water into the underside (where the battery is housed).

Love the copper finish! It cleans well and seems to hold temperature really well.

As most of us know, coffee is much more effective when it’s hot,  I work from home, and throughout the day, I used to put my coffee in the microwave 5 to 10 times a day and that ended when i got this smart coffee mug that allows me to set my preferred coffee temperature through the app on my phone. And it notifies me when that set temp is reached. The app works great, seamlessly connects with my phone with instantly. Its a game changer in my coffee life.

My husband and I each received an Ember mug as a gift. We weren't sure if they really worked. They do! We've been using them for over 2 years and love them! I'm a coffee drinker, but also drink tea. I'm able to set the temp that I prefer for whatever I'm drinking. We use them every day and recommend them to anyone who enjoys their coffee or tea the same temp with every drink.

The mug does exactly as advertised. I get about 1.25 hrs of usage out of this using the max temperature ( I like it uncomfortably hot). App has connectivity issues but can be fixed in future updates.
