Great products, Great company awesome customer service. Keeps my coffee hot. No need for an app. Simple, straight forward to use. The lid fits snugly and they offer travel lids. (All lids and bases are interchangeable) I've had it for 18 months and It stopped charging and i contacted company. They got back right away and helped me troubleshoot. Turned out one of the charging pins broke off. They sent me a new base. These days it's rare to to find a company that stands by their product especially after 18 month. Love this Colorado company. I've now Ordered a travel mug and a mug for my sister straight from their site as they were on sale. They have beautiful new colors in the 14 Oz. Mugs I've tried the ember and another from Amazon and didn't like either.

I have an Ember and Nextmug. I’ve had the Ember over two years and the base broke. One of the tiny little spring-loaded nibs lost its springiness. A weakness in design if you ask me. But, the Nextmug uses the same little nibs. Their design is a little stronger in that one nib is right in the center of the cup-base. But still, a weakness in design that you cannot (and I stress CANNOT) get the baseplate wet. I’m not sure what happened to my ember, but I ended up making a solid nib out of solder for the one that lost its spring. It’s holding, but I’m not confident in it. I’m guessing at some point, the Nextmug base will do the same thing. That aside, the Nextmug is superior for a few reasons. One, it has a definitive on and off option. Where the Ember has a sensor to know when you’ve added liquid, it’s hit or miss. The Ember on/off switch is also inconveniently located underneath the cup. And it also is hit or miss. Where it gives you a tactile response that you’ve clicked it, it’s unclear most of the time what you’ve actually done. Sometimes a light comes on, sometimes not. Sometimes it’s blinking red, sometimes it’s solid red, green, white, blinking… The Nextmug on/off is located on the side (superior) and it’s easy to know when the cup is off (no lights) and which option you are picking. The Ember app? Garbage. It is unreliable. If it works, it’s fantastic. The trouble is that it rarely connects no matter what you do. When I went shopping for a replacement, I specifically looked for cups that did not have an app. “App” means IT developers, means more cost, and generally for a product like this, average developers (I mean, it’s a cup not an air-traffic control system). Plus, the Bluetooth chips they must use have to be the bottom of the barrel (aka, unreliable). Therefore, all the features that the app provided (heating options most notably), were useless to me. The Ember cup size (10 oz) was a little small. There’s now a 14 oz option, but the train had left the station! The Ember on/off button on the bottom of the cup, again, is a nuisance. And here’s something I didn’t think I would care for… the Nextmug lid! I have to say, it’s great! It helps keep the coffee warmer without using as much energy (longer charge when it’s away from the base). Also, it nearly erases evaporation. And, I’m not 100% sure, but the coffee seems to be much less bitter because of it. Maybe my imagination, but the coffee taste better from the Nextmug cup. Plus, no spills (or at least, less chance of splashing). The Nextmug light indicators where intuitive and having a button for “warm, hot, and piping” versus an app… Way to go Nextmug! Between the Nextmug and Ember, it was an easy decision for me. I’m still concerned about the little nibs losing their springiness… But, there you have it.

As I write this I am using this amazing coffee cup. It does exactly as advertised. It keeps my coffee at the exact temperature I want. The battery charge last quite a while,,, lots of time to finish my "hot" coffee. Looks great too. Highly recommend.

I'm not sure what aspect of my being this comes from, but I was finding myself constantly grabbing a cold mug when I finally remembered it was there. I'd make a pot of tea, make my cup, intentionally let it cool, and one way or another it was too cool / cold by the time I got to it. I can't say that I've been monitoring how long it took for the mug to cool down, but it always seemed too quick. I was already looking for a reason to get a new mug as the rounder handle resulted in holding it in a painful way and it was frankly getting heavier to my hands as well (being ceramic). So I had a few reasons to look anyway. And with that in mind, I decided to look for something that might help with those issues or at the least, not let the cup's contents drop below a certain temperature Long enough for me to get around to drinking it, while also having a more comfortable weight and handle. Initially, I thought about those coasters that heat up, but felt that that'd be too much of a burn / fire hazard and likely not able to control the temperature as well. Seeing as how I didn't know what temperature I was waiting for it to cool down too, I knew that I'd want something with a measured setting. I was also looking for something that could heat up a cold cup to the desired temperature. When I first saw this listing, I was taken back by the price, but not so much that it kept me from looking into it. Especially since I have a habit of deciding on things that one way or another tend to push the budget. I looked at the various aspects of the design and saw that it was basically self-contained, so there was a little to no chance of being hurt by the mug (unless I spilled the contents on the upper two settings). Being able to choose from a known selection of temperatures was a must on this purchase. I also liked that the handle appeared (correctly) to be large enough to fit my average sized, closed grip. While I've not weighed it, it definitely feels lighter than a comparably sized ceramic. Most of its weight is, of course, the battery at the bottom. I was a bit bummed that the charger was a barrel plug as that doesn't allow me to just grab the nearest USB-C cord from my station (where I sit). That said, if it Did have USB charging, then it would have only been to the base anyway, so that would be a moot point since it would likely never get unplugged unless moved. While I don't know how much my old mug held, it's quite apparent that this is likely a few ounces less, but it's also exactly 1/3rd of the 1L pot when brewed vs ~2.5 fills with my old mug. I'm sure I'll get used to the difference eventually. Now, when evaluating the performance of this, it became apparent that I was running into my desired functionality vs its design. It has become obvious that this is designed to start with a hot liquid and keep it at the chosen temperature until empty or the battery runs out. It does that quite well, but I can't say how long the battery actually lasts for sure because I lose track of time too easy. So when I say that it 'feels' like it's losing power (not temperature) quicker than advertised, I can't quantify that statement, but it 'feels' closer to 2-2.5 hrs vs 4 hrs (lid on). I can say that I figured out that my comfortable temperature is the lowest setting and that the middle temperature more closely resembles my freshly brewed pot. The charging time feels like forever, but definitely a couple hours from depleted. Now when trying to see how it does with 'heating from cold', that definitely seemed to drain the battery much faster while also taking a long time. I even tried setting it to that middle choice and then turning it back down, but that still drained the battery rather quickly. So if That is how you want to use it, then leave it on the charger until it's hot again (and expect to wait a bit). I did have to stop myself from walking it over to the microwave the first few times until I got myself better trained with how it's designed. Because of this, as much as I hate adding to an already pretty penny, I chose to purchase a 2nd base to sit where I eat / drink. I thought about moving the original base, but then I realized that it was better to leave that there for when I've cleaned the mug (default storage location and all that). What improvements would I like to see? 1) Make a slightly larger (16oz?) mug, but have it be taller so that the base and lids don't change. 2) Source a higher density battery if possible. 3) Increase the speed at which it warms up (if feasible). 4) Add a little more texture to the handle / housing as it is metal smooth and slides a bit easy in the hands. 5) Offer a closeable lid as that should prevent spills and likely assist in keeping it warmer longer.

2nd UPDATE: It is now April 2026. A sad day. It seems that the mug no longer heats up, even when sitting on the charger. Time to be replaced. Total lifespan was just about 2.5 years for anyone looking to purchase. UPDATE: It is now May 2025. About a month ago, I noticed that the mug no longer held a charge after about 5 min. I sit near my coaster all day anyway (desk job) so I just kept it on the coaster and it was fine. Unlike the Ember mug I had, this still kept things hot while on the charger. But now I'm also noticing it seems to auto shut-off after about an hour or two, so I have to keep an eye on it to make sure it doesn't turn off. I'm a sipper so, yes, I do take hours to drink a mug of whatever! *************** I purchased this mug in Nov of 2023 and wanted to give it a good, long use before reviewing. I had previously gotten and used another, more expensive electric mug which is sold in all the stores at Christmas time. With THAT mug, you could set the temp of your mug via their app to a specific number and that was nice so I didn't expect to like this mug as much. But with the other mug, the coating inside the bottom wore off in about 6 months from stirring and after about a year, it really didn't keep my drinks piping hot anymore. With THIS mug, I use the middle (of the 3) setting, "hot" and it is piping hot for me. The hottest, "piping" is too hot (I used the max number on the previous mug to get it to the heat level I wanted). I have also not had a circular path appear on the inside bottom of this mug. And, a year later, it is still going strong. CAVEAT: I do keep it on its coaster the whole time and sip as I work (it takes me hours to drink a mug of something)... when I happen to be up and take my mug, without the lid, the charge lasts on HOT for about an hour. Maybe 90 min with the lid on. I am still quite satisfied! The previous mug's charger was concave and this one is convex, so I just had to get the hang of placing it on the charger correctly without it toppling over, but that was an easy adjustment. Both mugs are heavier than a standard mug (obviously - there is a battery in the bottom!) but I got used to their weight. I am very happy with my Nextmug and would buy it again!!

This mug works well, keeps coffee hot for an hour or two. It's a little heavy, but not much more than a ceramic mug. The controls are simple, and the three heat settings are sufficient for a good range of preferences. After a year my mug stopped charging, and the company did a warranty replacement quickly. Now after two years with the replacement, the same thing happened. Two years of use for about an hour once a day is a fair service cycle, I suppose, but not what I would expect from a $100 item. That's my only complaint about it.

I read the instructions and plugged in the charging coaster, which already had two green lights and charged it until it was fully charged at three green lights which took a while. The directions were confusing to read. But it wasn’t until I actually used the mug that I was able to understand them. I was also concerned about the length of time I could leave the charging coaster plugged in for charging. I went online and ask customer service whether the charging coaster could be left charging overnight, but never heard back from them. But I figured if the charging coaster could be left on indefinitely according to the instructions when drinking coffee at any temperature, I could charge it overnight. The charging coaster didn’t get hot nor did the plug. The first time I used the mug I had it on warm uncovered, which was the perfect temperature for me. My 1st cup of coffee stayed warm for just under two hours. For what I paid, I was not happy and thought about returning the mug. I chose this type of coffee mug because I need to use it without the charging coaster. So I tried again and followed the directions, using what I learned from my first cup of coffee. Pulsing lights, heating up, pulsing lights cooling down. There are pictures and few words, but I figured it out by just using the mug. For my second cup of coffee I did use the lid. I prefer not using lids, but it made sense not to lose heat. Warm is the perfect temperature for my coffee and it stayed warm for about four hours. Yah! The next test was finding out what would happen if I added coffee to the coffee left in the mug. (I make French press coffee and it doesn’t stay hot for long,). When I added the coffee, the light started pulsing letting me know it was heating the coffee. Okay! And it did and it was perfect and didn’t take long. The final test was a cup of tea. I made the tea in the mug and set the temperature to warm. Pulsing lights again but this time to let the tea cool down!!! One of the reviews I read before purchasing the Nextmug mentioned that the coffee tasted better. For me it’s that first sip of coffee that’s the best. But with the Nextmug all the sips taste like the first sip. It took me by surprise. Same temperature and same wonderful flavor from start to finish. I love this mug and highly recommended it. But it is a little pricey.

I love the mug but hate the price. I enjoy having a hot cup of coffee in the morning and this does that. I enjoy that as I drink my coffee it gets hotter...not colder. It's well designed, doesn't feel like cold steel against you lips like other mugs do. The battery lasts long enough for me to finish my coffee. I took off one star because I think these mugs are way overpriced. It's a nice splurge and I bought it with credit card points so it was free.
