This is great when you make extra hot beverage that you want to take with you and keep it warm.

Love the ember mug because it makes the perfect temperature for my coffee.

Works great, easy to clean and keeps a charge. My husband uses it every morning for work.

Stays hot but the lid that slides back and forth keeps breaking

I love all my Ember Products! Nothing like a Hot Cup of Coffee!!!!

Keeps my coffee hot I don’t need to be in a hurry to finish it

Works great and has lid.Fits in my cars cup holder.

Great quality, keeps my drinks warm for long periods of time.

Love,Love, Love my Ember to go! It really works and keeps hot drinks hot so you have time to drink it, I also have an Ember Mug. Love them both!

I had my eye on this for a while and waited until I felt I had enough BB points to get it. I'm so disappointed in this. I like my coffee HOT and the highest temp on this isn't as hot as I like my coffee. Plus, it's heavy and doesn't hold enough. I can't believe it's listed at the price it is. I'm returning it.

I purchased this for my daughter’s boyfriend who is a doctor (I got the idea from a blog written by a doctor about his favorite gifts). Shortly after we gave it to him, he texted me one morning to tell me how much he loves it. My daughter says he takes it to work with him every day.

I would give this product a 10 out of 10 if u could. Best money spent on a cup. I'm a teacher and i always end up putting my coffee down to teacher, but this keeps it warm for at least 4 hours before the battery dies.

Bought for a gift. They loved it. Would recommend to others.

works very well. nice to have in when placing in cold wisconsin truck in the winter.

Coffee is very essential in not just my life but also my wife's. This tumbler with a 16 oz capacity is great for sharing and keeping our coffee at optimal temperature. Connecting the tumbler to the phone via the app with Bluetooth was simple and quick. From there you are able to check battery life and set the temperature of the drink. The advertised battery life is 3 hours which if I'm honest haven't needed to keep if warm for that long while at most needing it to remain at my optimal temperature for less than 2 hours. Some complaints that I've noticed with this model is the fact that it won't fit in a car cup holder. The solution to that problem is simple. Get an expander for your tumbler. I carry this in my car with the expander with no issues with spilling. The 2 lid options are good and I primarily use the lid that you are able to slide. It's advertised as spill proof which at the moment holds true. Overall, this is a good capacity tumbler with the ability to retain a specific temperature for a long time satisfying the desire for a good cup of coffee in the morning.

Was the perfect gift for a guy who works outside in the winter and get busy ans forget his coffee in the truck! Easy to use, AND he actually likes the handle lid with all the things he had to carry into work.

I’ve had multiple ember products including two travel mugs and love them. This one is no different. Wish the batter would last more than 3hrs though. FYI, I’ve used mine mostly for green tea.

This doesn’t fit in cupholders. It also functions as a thermos rather than a travel mug— you need to remove the top to drink. It’s okay, but not what I was looking for.

I really liked this product, I just thought the lid was a little fragile

To be clear, I probably have a little caffeine problem, and very much enjoy coffee as well as tea. That said, I think this tumbler is excellent, does what it promises and does it well. I love the design. Simple. Clean. Plain. Matte black (mostly). This is more or less perfect for me. I like the look. I do really wish the lids were not glossy, but I understand why they are. A little nitpick, but just something to note. Beyond that, everything is built well. The tumbler feels solid and uses good materials (stainless steel…etc). The built-in LED used for status works well and is customizable. Honestly, however, I think its placement, while making sense, holds it back a little as it is not the easiest to see. The lids (one with a spillproof sliding lid, one with a handle) secure perfectly, do not leak, and are dishwasher safe (the tumbler is hand wash only). The charger is rather compact, has plain styling, and has a good build. It should never be an issue. In use, I am happy with “nearly” everything Ember has done here. It’s a pretty simple concept, and they nail it. In short, when it comes to keeping your drink at a constant temperature, it just works. Pretty much full stop. It just makes my whole experience better. My main two concerns are that is seems to lose initial temperature a little quicker than other tumblers I have used and that when drinking tea (which is normally a little hotter for me) that heat transfers to the outside surface making it a little warm to the touch. As for my first concern, I guess it is nothing more than another nitpick, as the tumbler does a great job of keeping my drink at a temperature I actually want to drink it at. As for the second, that is somewhat of a personal thing, and it may not apply to you, again, just something to note. Taken as a whole, it works, and I like it. The app, while not “really necessary,” is simple, intuitive, and useful. Drinks will default to 135°F, but can be set anywhere between 120°F and 145°F within the app. I really think it is worth it to play with it to dial in your preferences. Why not find out what you really like? You can also change the LED color here. Lastly, you can also see your charge status and set yourself up to get notifications when your desired temperature is reached as well as when it is time to charge your tumbler. As for battery and charging, I think it is good. I think a lot of this will depend on your use case and what you are looking for. On a single charge, it lasts roughly three hours. For me, this is not an issue, and I “think” should not be for many others, but again, check your use case. If? you are using this at home, you can easily just place it on the charger and never have to worry. Ultimately, I really like this tumbler. It does what it promises to do, and it does it well. It has a good build, looks great, and is simple to use. It is, however, somewhat of a luxury product. For someone who will use it daily, or often, and is looking for consistency and convenience, I think the value is there. It is for me.
