I wasn’t sure if I would actually use this but I use it everyday at work!! I set my temperature on the app & I don’t have to worry about my coffee getting cold!

Great mug. Love that it’s not hot on the outside but the drink is hot inside. It works great. I wish they made it a little bit bigger like 16 oz and somehow make it last a bit longer. But great concept and works very well. Coffee is hot till the last drop!

I cant finally come back to my coffee after working and its still hot. The best part is that I can set the temp I want with my phone ahead of time to make sure I get the hot coffee I am expecting.

This cup definitely keeps the drink warm much longer. Which is exactly why I got it.

My wife loves her coffee and she loves it hot. At first we were skeptical but it does the job and does it well. Her last sips are as hot as the first ones making the entire cup enjoyable. We bought the white version and there is noticeable staining after some time. I’m not sure this will last forever like a regular mug but a great concept and performs well. The price tag could be less but if hot coffee or beverage is important to you to the last sip this is a must have.

I’ve had my ember 2 mug for a little over a year now and I absolutely love it. It does what it’s supposed to do and it does it reliably. The app is easy and straightforward also. Get the lid to basically double your enjoyment. Instead of a little over an hour of drinking time I get at least 2 hours of hot coffee. I like this mug so much that I bought 2 more as gifts. Seriously my favorite gadget that I get the most use out of.

Got this for my wife as a mother's day gift. She has a habit of leaving lukewarm tea all over the house. She loves it and it prevents her from nuking her tea in the microwave every 30 minutes.

This mug keeps my coffee at the perfect temp for a long time. But the most important thing is that it is not harsh with its heating element. The coffee does not develop a burnt taste that you might associate with a hot plate. The app is fairly simple. I did have some connection issues at first, but it seems that was user error.

Love this mug! Gave it to my sister for her birthday and she turned around and gave me one for mine. I absolutely love it. I like my coffee hot and really enjoy not having to drink it quick before it gets cold as I have had to do since I started drinking coffee 50 years ago! Nothing like a leisurely cup while reading. The 14 oz mug gives you enough room to add cream. Initially my sister gave me the 10 oz which I found to small.

The mug is a nice design and weighs about the same as a regular coffee mug. Coffee does stay hot but if you dont pick up the mug for 2 hours it will shut off. Overall its a great product.

This is easy to use and great to keep my tea warm for hours!

It's a nice mug that may keep your coffee warm, this is for someone that needs it for additional hour (or 2 if you're pushing it) of good coffee (or tea, whatever you prefer). However, the battery isn't that last-longing. You have to charge it every usage. and that takes around 2-5 hours depending your habits and how often you charge your mug. If I have to be honest, I think you're better off with a double-insulated tumbler/mug that may keep your drink warm up to 5-8 hours a day.

Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

My wife loves it. She's a sipper, I'm a gulper. Her coffee has been hot all morning. She even takes it down to the bus stop and folks ask her how her coffee is still steaming when its freezing out!! So, yeah, she loves it. I clearly haven't been able to try it yet, because SHE LOVES IT SO MUCH. It took a few tries to learn the right temp settings to keep her Nespresso from getting a film, but she's found it and there is no turning back. (Might be a little pricey, but got it on sale and her smile is worth it)

The coffee cup is a neat concept. Is it worth $129? Probably not but it does keep my coffee hot. Saying the battery lasts 80 minutes is very optimistic. Keeping my coffee at 140 degrees give me about 30 minutes before the red light comes on and it no longer warms my coffee and I have to put it back on the charger. Finally, you need to download the app to be able to adjust the temperature. I would prefer a "dumb" version where I could adjust the temperature on the cup itself.

Great cup to keep beverages hot and at your choice temperature. Lasts for over 4 hours off the charger. Sometimes it’s difficult to connect to your blue tooth. Other than that great coffee mug - love it! Would recommend

This is the 5th Ember mug I have purchased, with three of them as gifts. They have all been a hit as gifts and I personally love using mine every day. I am a verrrryyy slow coffee drinker but this keeps your coffee or tea at the perfect temp. It may not heat up liquid from cold, but it will heat up lukewarm liquids to the perfect temperature.

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.

Very usefull but a bit expensive. I enjoy drink at golden temptature while I am playing video game. I don’t have to worry about my drink getting cold.

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.
