Nextmug - Temperature-Controlled, Self-Heating Coffee Mug (Slate Blue - 14 oz.)

I am an all day coffee sipper, but my coffee often cools down if I'm not paying attention. This Nextmug resolved that issue. The best way to use it is to put in hot coffee, put on the lid, and set your temperature. It's all very simple and it works perfectly. The cup itself feels very "high quality", and the cover is very strong and well made. Finally, I had a minor issue with mine; I wrote the company, they replied within 24 hours, and went above and beyond to make me happy. Great customer service is always the clincher for me. It's somewhat pricey, but you get what you pay for. I have no problems recommending this mug. Besides, if you don't like it return it within 30 days. Enjoy!

I’m so glad I found the Next Mug! This temperature-controlled coffee mug does exactly what it promises—it keeps my coffee hot for hours without making it taste burnt or overcooked. I love that I can sip at my own pace without worrying about reheating.The design is sleek, and the color choices are surprisingly stylish and modern. As a mom of three this mug is super easy to use and keeps my coffee hot! It’s so nice to have warm coffee and I’m not warming it up in the microwave 2-3 times a day.I’ve had this mug for two months now and the quality of the mug is amazing! It holds a large cup of coffee and it stays charged for a while. Overall highly recommend this mug!

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.

I bought this for my wife since she likes a 1:1 coffee creamer ratio. Also, she takes her time drinking it, so it gets cold fast and I was tired of reheating the same cup 2/3 times a morning. This does the job well! In fact, the lowest setting is enough for her, so the battery lasts longer. My only two complaints are that it dies very fast when off and not on the charger, it has very diminished charge retention. And, the most coffee you can put in it is 10oz which leaves the smallest amount of room for creamer. Otherwise, it looks great and the induction style charger is such a cool concept for waterproofing!

I LOVE having a mug that keeps my coffee warm until the last drop. This is great for me and I use it every day. My only issue is I should have opted for the larger model. I would love to have that model and may give my mug to my wife and order the bigger mug. It works perfectly and I have exactly NO problems with it. I poor my hot coffee in the mug - switch it on and enjoy. I have found as I get near the bottom of the cup I have to switch it off because the element is pretty powerful and even too hot as I get to the last swallow! Love it!
