Customer Ratings & Reviews

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

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

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.

Get it. Yes it is incredible. Saving money on coffee creamer and enjoying better coffee.

LOVE this cup! I use it every day! It comes with 2 different lids which is an added bonus.

Great mug fits my cup holders dose what it’s suppose to do no weird taste.

Got this as a Christmas present for my husband and he loves it!

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 got two cups for my sister and her husband. One was the tumbler and the other was the mug. The cups are fantastic BUT when the app doesn't work, the cups are difficult to use at best. I feel like the cups are just a huge risk since it requires app support. We're trying to figure out if we want to keep them currently.

Shuts off on its own. Doesn’t stay hot like my ember mug does. My mug stays hot up until the battery runs out. This tumbler will shut off when its still half full with coffee and when I check the battery its half full too.

It was good while it lasted, but no longer works and Ember has not responded to support requests even after two weeks. They do everything to avoid helping you: There is no phone number, and they make you go through a bunch of FAQs and such before even letting you email sipport. Then they dont answer anyway. Not sure what I’ll do with my $160 useless “smart” travel mug.

Mug refused to connect with app both on android and ios, the mug takes forever to heat. A regular mug is much better to keep my tea hot than the Ember mug. Just disappointed generally.

The Ember - Tumbler, 16 oz – Black works just as it stated to work on its box. It has the ability to keep the temp of beverages (mainly coffee or tea) between 120°F - 145°F (50°C - 62.5 °C). I was able to take programmable functions of the Ember - Tumbler, 16 oz – Black by installing the Ember app. With the Embler app, I can program my tea to 137°F and receive a notification on my phone that my tea is ready to drink. The Embler app also has a timer for seeping various types of teas (Black Tea, Green Tea, and Herbal Tea). The Ember - Tumbler, 16 oz – Black kept my tea hot for over an hour at the temperature I set with the app. What I don’t like about the Ember - Tumbler, 16 oz – Black is the heat transference after pouring a boiling hot beverage inside it. It is impossible to handle until it cools down and I cannot travel with a beverage too hot (at boiling temperature). Also, it is too small to have a tasty hot beverage last for three hours. It would have more usefulness if it was a full one liter container. I finished drinking my beverage in less than an hour and then it must be carried around outside. The Ember - Tumbler, 16 oz – Black is simple to use through the app and manufactured with high grade technology. It keeps my hot beverage at the precise temperature that I set with the Ember app. I can drink two cups of any hot beverage for up to several hours, if I need too.

NO START TO THIS PRODUCT HORRIBLE IT DOESENT HEAT AFTER 2WEEKS OF PURCHASE TO MUCH MONNEY FOR THIS $165

The Ember Tumblers is delivering what is designed for. With a 16oz size, you finally have the right size for our breakfast drink that with the Ember proprietary technology can be maintained at the exact temperature defined by the user in the app. In the box, you can find all needed to use your Tumble: the tumble, two lids, the “charging coaster” and the full power adapter. One of the lids is designed for carrying liquids with a full lid closed and the second one is for regular sipping. Consider charging your mug before first use (less than one hour for a full charge) and during the charge, consider downloading your app and creating your account. The app goes very fast as your account, perhaps (depending on the version) you could also be required to do a software upgrade. This goes in less than 10 min. After charging and with the app installed, thanks to the Bluetooth connection, you will have both devices paired. The app basically serves you to define the temperature at which you would like to have your drink. A few comments here: .- Temperature options are between 50 and 62 Celsius (120 to 145 Fahrenheit). Yes, in the app settings, you can also define your unit scale. .- The design is to introduce a warm/hot drink and to keep it at the defined temperature. Doesn’t seem to work if you introduce a cold drink and you plan to warm it up. .- The battery can keep your drink at a defined temperature for three hours but this is more than enough for me. I drink my coffee faster than that so I can only refer to this with the specs. For cleaning, despite some messages in the instructions about keeping the bottom side of the tumble dry when you are charging the battery, thanks to the stainless steel material, the tumbler can be cleaned directly (always hand wash) by submerging it under the tap. Just keep it dry for the charging. On the good news side, the two lids are dishwasher-safe. Basic, easy-to-use technology and app that delivers.

This mug seems to shut off while in use and says it is empty when its not.

My wife has many of the Ember mugs and was really happy to get this Tumbler with more capacity while still being able to connect easily with her app. In this version of Ember products she appreciates the new lid with handle, the smaller charging station coaster, the adequate battery life, and the fact that it can still charge on her other Ember coasters if needed. Her wish list for small improvements includes having it just a tad bit bigger as 2 cups of coffee are a tight fit for it as she mostly uses it for storage to replenish her mug. (so she didn't have a comment on the sipping lid but its great that it comes with two lid options) Personally I think that means you drink too much coffee. LOL While the Tumbler fits in her vehicle's cup holder, her other wish is to have it be compatible with her car charger. That is the charger she probably uses the most with her travel mug. So besides the minor wish list for a future version, she is very satisfied with the Ember quality and performance in the Tumbler that she has come to expect each and every day with her other mugs and travel mugs. With the addition of the Tumbler, she now has enough warm coffee for work!

Very fragile and is not made for heavy use. Do not recommend.
