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 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.

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

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.

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

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!

I have used an Ember mug before and it works great to keep hot drinks like coffee or tea hotter longer than a ceramic mug would. I always bring a tumbler around so when I want to bring my coffee to go it would keep my coffee hotter than say a paper cup and it's also reusable. So I figured I would give this a try because why not. This tumbler is 16 fluid ounces in size and comes with the handle top and a top that gives you a mouth piece as well if you rather use that than just opening the top itself. It also comes with the AC adapter and charging base as well which works like wireless charging your phone. Just put it on top and it charges. You also download an app to set the tumbler up with bluetooth connected to the tumbler as well. You can set a temperature that you can keep the coffee or tea at as well. As far as the battery life goes it lasts long enough where it's not a hinder for you to use it multiple times as well. Also connecting it to your phone is quite easy with only one button on the bottom of the device which you can use to turn it off, on and connect to a Bluetooth device.

I have been putting the Ember Tumbler through its paces over the last week. Since it is for keeping things warm I have been using it for my coffee daily. First off, the Ember Tumbler feels well built and has some weight to it, but not too much. I would say it is about 20% heavier than my Yeti tumblers which makes sense given the battery/heating element inside. Second, it does work and works well for about three hours which is what Ember estimates. I would say on average at the 135 degree F setting my coffee stays warm around 3 1/2 hours. Additionally, it came with two lids. One for drinking and one for carrying around if you are using it for something else (like soup maybe). The drinking lid even comes apart for washing which is very handy. It has an app that connects to the tumbler via bluetooth and will allow you to set the temp and see what the current temp is. It's a nice setup and clearly Ember has been evolving this over the years. So why three stars then? Well, first off, the insulation quality isn't great. The outside gets quite warm when in use and without the heating element working things cool off very quickly. Much faster than my 'standard' vacuum insulated tumblers. And forget putting anything cold in because it won't stay that way long. So, this immediately places the tumbler into a very narrow set of use cases for me. Basically it is my coffee cup and nothing more for my lifestyle. Next, the charging requires you to pay close attention when setting it on the base as I have found myself twice without a charged tumbler in the morning and that makes my coffee sad. The handwashing's situation isn't a problem, but you do need to make sure you dry it thoroughly due to the charging contacts on the bottom. Maybe I didn't get it completely dry and therefore it didn't charge? I don't know, but you definitely want to pay attention to the light on the tumbler at the bottom to insure it is charging properly. Lastly, it is hard to easily gauge how much battery is left. Yes, one can go into the app and then into settings to see what percentage it is at, but that isn't exactly convenient. At least place the battery indication on the main screen of the app with the current temp. The Ember Tumbler is a very neat concept but needs a little more refinement to make it worth the asking price. It might be the right value proposition for some, but one might need to be drinking more than just coffee to make it so.

The Ember tumbler is a very well-built product that does exactly what it says it does: keep your beverage hot for an extended period of time due to a built-in heating element. The product is high quality, it feels really good in the hand. Included with the tumber are two tops, one is the handle you see in the picture which unfortunately does not allow for drinking. The other is allows for drinking - it has no handle. It has a slot that opens and closes allowing you to drink / save heat. The best part of this top is that the drinking apparatus is removable and can be cleaned. Unfortunately, the only way to operate the mug is through the app. Without the app, it is just a glorified mug, ALTHOUGH, if you setup the mug initially in the app, it will remember your settings going forward so in reality, as long as the mug is charged, you will never have to use the app after the initial setup. It just becomes a nice means of tracking the battery life and controlling the temperature if necessary. The app is nice, I will say. They say coffee is 135 degrees. In reality, coffee direct from a drip coffee makers is at 165 degrees. After adding a little milk from the fridge it drops to 145 (tested with a thermometer). As a result, I pushed the temperature control above 135, which maxes out at 145, which matches what I make with the drip coffee maker plus milk. I did some tests for battery life. If you attempt to use this product to heat a drink from cold, you will get 1 hour of battery as the heating element is using too much energy. I heated 66 degree tap water and the battery was exhausted after an hour and the water topped out at 120 degrees. I mean, it isn't terrible but 120 isn't hot enough for those who like hot drinks. If you use the device as intended, that is, putting in a hot drink and keeping it hot, you will get upwards of 4 hours. I put in 165 degree water from a tea kettle and the Ember tumbler kept it hot for 3 hours at the max (145) setting. I assume that if you do lower temperatures you will get longer battery life. Of course you can always use the device while its charging. The charging mechanism is a pad that has some charging rings on it. It allows for any orientation of the mug. I.e. it doesn't have to be facing one particular direction. I would have preferred a much more visible LED indicator. It is a very small one at the bottom of the mug. The app lets you change its color, but that is just a novelty. Overall, I give the product itself 5 stars, but at $200 I have to knock it down a star. You can get a super high quality thermos-style mug for much less, which is all most people need as they intend to drink their beverage not too long after putting it in the mug, at least that is my intention. Even in the case where I consume my beverage later, I am usually near a microwave to reheat it. As such, I think it's a great quality product and unique concept that some people may find useful but I can't recommend it.

Looks plain and simple but the build is solid with aluminum, plastic and the bottom has rubber/silicone to keep it from sliding. It comes with a charger/coaster, a screw on lid with a handle and a non screw on lid with a sliding cover. With the tumbler full of water, It took 1 hour 20 minutes to warm the water from 70 - 135 degrees Fahrenheit while on charger. It took about 3 minutes to go from 125 to 135 and consumed 3% battery. Maintaining the 135 degree temperature in my room temperature of 74 degrees for 15 minutes took 18% of battery. After sipping my coffee for 30 minutes, the battery level went from 94% to 60%. This is without using the lid. Battery life is good enough for my needs. There’s a power button on the under side of the tumbler but I haven’t figured its best use yet. If you set the heater off in the app, the power button is pretty useless. I think some button gestures should be added like a double tap that would turn the heater on to your desired temperature. Come on Ember! Without the app, there’s no way to change the temperature from the factory setting of 135 degrees. There’s a status LED at the bottom of the tumbler. The LED breathes white while it warms up to temperature you set. Solid white when the set temperature has been reached. You can change the color of the LED to your preferred color so that you can easily tell that it is your cup. It only shows that color when the heater is not on though. With the heater off, the preferred color will glow every time you move the cup. This cup will help me keep my coffee warm in my office where the AC is always on and now I can take my time sipping on it.

I love coffee… anything that makes that drink better…I love that too and Ember keeps my coffee temp right where it needs to be AND I love Ember for that! What a great product! Got my Ember 16 Oz and downloaded the app. Super easy set! charged it up for the first morning run the next day. 5 am came too early as it usual does but I was excited to use the Ember. Brewed a pot of my finest grounds and poured it in the Ember. It’s smart, it turned on when I poured my coffee and turned off when I finished it. Really cool! I love that I don’t have to take my cup back to the microwave a couple of times as I had to in the past…or when the coffee is sitting in the craft but doesn’t quite stay hot enough with the craft warner so I would have to microwave…. Those days are long gone! Ember had a consistent temp the whole time I enjoyed my morning coffee!!! You can also set it on the charging coaster and get the right temp all day if you’re a coffee junkie like me! I also liked the two lid options. The handle is great for pouring a cup of coffee and storing it in my bag as I head out the front door for work with no leaking! The sipper is great for sipping from the get go! Both lids are dishwasher safe but you need to handwash the Ember. It is IPX7 which means you can submerge in water to wash. With coffee I usually just rinse it out but it’s nice not to have to worry about shorting it out with water! It looks sharp and feels great in the hand. Over all if you are a Coffee person or any hot beverage person, this is a MUST HAVE! It really keeps the first sip as good as the last! LOVE IT! I wish they made an Ember cooling tumbler as well for my beer! Can’t go wrong with Ember!

The packaging was simplistic and easy to unbox. As you unpack it you come across instructions and warnings. It comes with two lids. One being a handle that twists off. The other being good for sipping. I prefer using the handle because I will walk around work with it. It is a good and bad thing that I had to download the app. I wish it just kept my drink warm without the app. However, the app tells me the charge of the product, allows me to adjust the temperature and keeps track of how much caffeine I had for the day. It is the perfect size, not too big and not too small. The lights on the outside of the mug describe whether it is charging or charged. The lights also show if the temperature is ready to drink at my desired temperature. I did have one weird day with it so far. It told me the battery was low after taking it off the charger 45 minutes prior. The first few days I was able to let it sit in the office for a couple hours and then receiving that message. I wish I knew what level the low charge was. On the app it does not give me a percentage. The product mentions it auto turns off but I'm still unsure if I'm doing something wrong. I am hoping this one day was just a fluke because so far it has become my favorite tumbler.

It keeps my hot beverage at just the right temperature, it easy to use, and I think it as a cool, sleek look. Design The Ember Tumbler has a sleek rounded look all around. I think it looks very good, and normal, not like it has a battery and a heating element in it. There is a LED on the base but even that doesn't really stand out. The body of the has a mat finish and doesn't show fingerprints. It comes with two. Each have a smooth, shiny plastic finish. The bottom has a power button in the middle with two concentric metal rings around it so it will charge when turned any direction on the charging base. But the bottom of the tumbler has some extra weight from what I would guess is the battery and other components. That helps to make it more stable than you may think. Features You will want to install the app. It enables the key features and allows you to see the battery level, temperature, and adjust the temperature. Among other things. You need to give it 10 or 20 seconds sometimes to notice a change, like when you pour a drink in or turn it on for it to tell if it's empty or not. But it works great. It will tell you the current temp and you can select a preset item/temp combo, or edit any of those. For instance, they have Latte at 131 degrees (F), Coffee at 134, and Green Tea at 137. There is also a timer for Steeping your tea. There's even a link that takes you to a handful of beverage recipes. It does a great job maintaining the temperature for a 2 to 3 hours. It's sort of weird at first actually when every sip you take, even after 2 hours, is still hot. I've been a bit sick the last few days and mostly used it with tea. I'm used to drinking my tea cold after a while but have really been enjoying it hot to the last drop! It's great that the tumbler detects when it's empty and shuts off so I need to to worry about wasting the battery or running it dead if I don't turn it off right away. Lids There are two lids that it comes with. One screws on and off, as you may expect, and has an easy to grab handle. The other lid presses on and pulls off. The second has a slide to have it closed or open to reduce spilling or to drink from respectively. I said reduce spilling because, unfortunately, it didn't prevent spilling for me. It just slows the rate that your drink comes out at. I think that's pretty common in general but I was hoping they got it perfect on the Ember. I do like the design of the slide in that it locks on from underneath the lid. You can unlock the sliding mechanism to completely clean it and it will not fall off when you drop it. It just doesn't completely seal when closed. I normally use the lid with the handle because I really like the handle to carry it. Charging Base The charging base works well. The spot for the Tumbler is recessed so it would be hard, maybe not even possible, to put the Tumbler in wrong and have it not charge. The power cord is about 6 feet long and has "brick" attached to the plug that goes in the wall outlet. Summary The Ember 16 oz Tumbler is an excellent choice if you want to have your hot beverage kept a just the right temperature for an extended period of time. It does that very well and, like I mentioned before, it's almost strange that the drink never gets cold! It works very well and the app is simple and makes it easy to see and control the temperature. I normally use the lid with the handle but was pretty disappointed that the lid with the slide is not water tight. It's slows the liquid from coming out a lot but it's a lot more than a few drips that still comes out. Because of that I have to give this four stars. Still, the Ember Tumbler does what it says and does that very well!
