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

*Update* - I've had this mug now officially 2 years. It was starting to lose some battery life and I had a few issues with it. I contacted Nextmug to get some advice and assistance and after answering a few questions they are sending me a replacement mug. Their customer service is stellar. Their product is fantastic, but if anything goes wrong, it seems they will do whatever they can to make it right. Best purchase I've ever made -and I would make it again. I love my nextmug - best bug like this for the price by far. Highly recommend. Now that I have used this mug for 6 months, I feel I can provide a completely honest, inclusive review. I had been using Ember mugs for several years and when my latest Ember stopped working, I wasn’t willing to shell out the big bucks on another and began searching for alternatives. I found Nextmug and decided to give it a shot. Nextmug vs. Ember Mug: A Comprehensive Comparison 1. **App-Free Experience**: Unlike the Ember Mug, which relies heavily on its companion app for customization and temperature control, the Nextmug offers a hassle-free experience with no app dependency. This simplicity appeals to me and I much prefer straightforward functionality without the need for additional software. 2. **Extended Battery Life**: One of the standout features of the Nextmug is its impressive battery life, surpassing that of the Ember Mug. With longer intervals between charges, I find I can enjoy my coffee throughout the day without constantly worrying about recharging. 3. **Convenient Lid Design**: The inclusion of a handy lid adds practicality to the Nextmug, providing spill-proof protection and heat retention capabilities. This feature enhances my experience by offering added convenience and functionality. 4. **Temperature Control**: While both mugs excel in maintaining beverage temperature, the Nextmug offers competitive performance without the need for constant app monitoring. Its intuitive design allows me to enjoy my coffee at my preferred temperature without any fuss. I find I don’t need the ability to pick a super specific temperature, the 3 settings are adequate for finding my perfect temperature preference. 5. **Design and Build Quality**: Both mugs exhibit sleek and modern designs, but the Nextmug's durable construction and thoughtful design elements, such as the ergonomic grip and spill-resistant lid, contribute to its overall appeal. In conclusion, the Nextmug emerges as a commendable alternative to the Ember Mug, offering a seamless user experience with its app-free operation, extended battery life, and convenient lid design. The Nextmug delivers on both functionality and convenience, making it a worthy investment for anyone in search of a smart beverage companion. And with a price that is quite reasonable compared to my ember, it’s worth the investment in my opinion.

This mug keeps my coffee warm without any complicated fuss. Never understood why I need an app to program my coffee mug or why I need to set the temperature to an exact value. This one has 3 settings: Warm, Hot, Piping. The latter to be taken seriously. One simple button to step between those settings and off. Battery lasts a couple hours which is all I need to survive through half-day meetings. The mug cleans easily and is stylish enough to not call attention. The only issue I have encountered is that if the mug is on to a particular setting and you add hot fluids to it, the controller gets confused. Just remember to turn it off before filling. Otherwise, very easy and intuitive to use.

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.

After 15 month the mug would no longer keep heating and Nextmug offered to send replacement even outside warranty.

Received product. Did not know needed Uk adapter for plug-should be in description. Otherwise would give 5 stars. However mug is fantastic. I set it on ‘hot’- lasts hours with cover on. Love this product.

Lo di a mi esposo para Navidad. Le encanta. Lo trae con el todo el tiempo! Puedo recomendarlo a todos que disfrutan su cafe!

At first great, does yellow with coffee but the aftr 9 months the battery will not keep its charge anymore. Tried customer support with no success

Beautiful..
