Make Nextmug your next Mug….
This cup is incredibly versatile and has three heat settings: 130°, 140°, and 150°. These settings work well for me, allowing me to brew tea, coffee, and hot chocolate to my preferred temperature. The charging coaster pens are significantly larger compared to competitors, providing ample power for charging. Additionally, the cup displays the current temperature and battery level at a glance, making it easy to monitor its status. The 18-ounce capacity is perfect for my needs.About nine months ago, I bought a competitor’s cup (the largest available 14oz). Unfortunately, I didn’t use it for more than nine months. It began overheating, causing the charging pens to burn. After burning up three coasters, I realized that the problem wasn’t the charging stand; it was the cup itself.

Great mug
Best mug ever. Now a year old and I drink several cups of coffee per day and it still keeps it hot. The highest temp is really hot so I tend to use the mid level setting. Hot but not scorching. My husband had the next smaller size as he only drinks coffee in the am. He has now taken this one as he can use the largest coffee fill setting on his kerig coffee maker. I have traded up to the 24 oz size. These mugs are pricey but I have bought them on Black Friday. Well worth it.

5 star on all counts as long as coating holds up
So far I give this a 5-star review, however, time will determine whether the coating holds up better than Ember. I like the larger 18 oz size of this mug, and the feel of the coating. I defected from Ember mugs as their coatings do not hold up over time. Considering the cost of these mugs, I want it to last more than a year and not worry about the coating material seeping into my coffee or tea--not to mention it just looks gross.What I like better than Ember:1) Nextmug is a manual operation with simple on-off and temp buttons on the base of the mug. It can be set to one of three temperatures (At first I was setting it to the highest temp, but found that the second one is better for me for an easily drinkable temperature.)2) I also like being able to turn it off when I finish the cup to prevent the congealing of remnants on the bottom of the cup like happens often with the Ember mug (yuck), and that it doesn't drain bandwidth from my wireless network.3) Also I found that Ember mugs would not heat the liquid back up if it had cooled down (this happens if you have the mug off the charging coaster for too long or leave it sitting for too long). The Nextmug also has an auto shut-off, but it will heat the drink back up if you reset the temperature.4) I like that they include the lid with your purchase. This helps keep the drink hot longer, which preserves battery life.Tips:1) I don't use a metal spoon and keep a plastic spoon (you know, one of those heavier duty ones you get from the froyo stores?) by the coffee pot to stir sweetener or creamer with these mugs, just to prevent unnecessary scratching (as I did with Ember), and only hand wash as per instructions from the manufacturer.2) I have also purchased two additional charging coasters so I can have one by my living room chair and by my desk where I spend the most time, and one in the kitchen for overnight charging.All I can say is if the coating material doesn't degrade like the Ember mugs have (I've seen this happen on the three different Ember mugs we've owned as well as several my daughter and husband have purchased), it will hands down be my preference and recommended self-heating mug option. I will update my review if I see the coating begin to degrade, but I purchased this in Nov. 2024 and so far so good.

Hot coffee for hours
I purchased this for my husband for Christmas and it has become his new favorite. This is a solid build and performs like champ. It came with easy to understand instructions. The cup sits on a base and keeps the coffee warm for hours plus the cup heats itself allowing you to take the mug with you while it retains it heat. It is a sleek beautiful design, with a lid to help contain the spills or splashes.

These work great but are pricey.
I bought this one for my husband and so far it is working great. It’s the second one we purchased. We have had the first one (mine) for almost a year. Keeps coffee hot.Mine will now only turn on if the mug is set on the charging disc for a moment and then turned on. It then shows a full battery and can be instantly taken off of the charger. If the temperature is changed to another setting while off the charger, the mug will shut off, or if the mug sits for any amount of time it will also shut off even though it still has full, or near full, charge. I was able to get it to work for a small amount of time by doing the reset process of holding the power button down for 5 to 10 seconds on each of the settings (once the mug was turned on by the charging disc) and advancing to the next setting, but then it would go back to doing the same thing it was doing before after a short bit. It has worked for the longest amount of time once I left it on the piping setting and let the coffee mug heat up all the way and then shut it off so far it will still turn on every now and then.We have let the company know this and they have been very responsive to the emails. Hopefully if you have these same issues this will help. The mugs are made very nice and mine still looks like new. I do think they could be a little cheaper on the price though. I would have purchased for Christmas gifts if they weren’t so expensive. Super easy to use when they work and hold a charge very well if you don’t want it on piping all the time. piping is SUPER hot lol. It is very true to its name lol.

Simple, easy to use!!
The wife speaking. I absolutely love this self-heating coffee mug!!! my husband used to make fun of me because I would never finish my coffee before it got cold and now it doesn't get cold any more. I love there is NO APP with this mug!! one button and super simple. I have the 18oz mug. I really like this mug came with lid and that I did not have to buy it separately. I will be recommending this mug to friends and family in a heart beat!!

Great, While It Lasts!!!
This mug does what it’s supposed to do very well, but it’s unreliable. The first one I received didn’t work, but customer service was good and they exchanged it. But that as of yesterday just stopped working. I trade very good care of things. It lasted less than a year. Not a good bargain at the price!
