Smart Mug - Fine Bone China, Dishwasher Safe, Luxurious Self-Heating, Wireless Powered, Hot Fully Automatic Heated Ceramic Coffee and Tea Cup - Pink

This product is designed to keep the fluid in container at what the manufacturer considers to be the optimum temperature. You have no control over it. It only works for an hour off of the base plate. It will not charge with liquid in it, so if you don't drink your beverage in an hour, you are out of luck. You will have to dump it out before you can recharge the cup. It also appears to be fairly fragile. Very Very pricey for what you get.

Self-heating mugs is a must in a working areas, especially when the environment is always cold.GLOWSTONE is a Nice fine bone china mug. It works.Good points:- nice design- fine bone china makes you feel the coffee taste- easy to clean- you can't control the temperatureCons:- you can't use it while charging. Once you put it on the charger it will stop heating.- you can't turn it on, it detects the hot liquids automagically. Sometimes it did sometime it didn't.- you can't use it to heat a cold drinks like Ember mug.- I found it hard to use it twice a day. Since it takes time to recharge. So you have only one shot per day.I used Ember before, it is great alternative but it won't last for more than 3 months before the taste changes and the steel is getting a weird scratches in the bottom. That's why I think the fine bone might be better in this.If you drink coffee one time perday go for GLOWSTONE. if you sometime bring coffee fromoutside and would like to have something that can heat even non hot drinks for you go for Ember.

I was an early adopter of the Ember Bluetooth coffee mugs. I've used both generations of Ember travel and a couple of different self-heating standard mugs over the last half decade-plus. The Glowstone ceramic smart mug is a direct competitor (and the best I'm aware of) to Ember's dominance. If you are considering a self-heating mug, I hope this review will help you choose between the two.First, why get a self-heating coffee mug? I am a huge fan. Coffee (especially higher-end, single-origin, fresh-roasted) changes taste as it moves through various temperatures. It is most enjoyable in about the 130-135 degree range. Most of the time mine comes out of the pot at about 170, and without a self-heating mug, drops to the 110's by the time I finish it. I only catch that sweet spot for a few minutes, and if I miss it I find myself struggling through too-hot coffee or just drinking the cold stuff for the caffeine and not the flavor. Self-heating mugs let the temp drop to the sweet spot (not insulated) and then heat as needed to keep the temp where it should be. Ember allows you to choose this sweet spot for yourself via Bluetooth control from your phone. I personally like this because I am a nerd and even track which coffees I prefer at different temperatures (Just so you know, the fruitier, brighter flavors do best at about 130-133, while nutty/earthy/chocolate is usually best at 133-137). The Glowstone doesn't allow you to pick; it seems to lock in at just about 135, but I haven't measured it to verify. Regardless of which you choose, I give the concept of a self-heating mug an enthusiastic 5-stars! It is my preferred way to drink coffee at all times, and I have only grown in this preference over the last 5 years.Appearance and feel: First, the Glowstone fixes one of my biggest complaints with Ember. The Ember is made out of dense plastic and doesn't "feel" good at the mouth. This, in my mind, is the biggest attractor to the Glowstone. The mug doesn't "look" like a piece of tech. If you didn't know, you might just think it was an attractive, standard coffee mug. Glowstone wins this category.Charging: The Glowstone charges via an included Qi charging pad but can charge on any Qi surface. However, and this is the biggest limitation in my mind, it cannot charge while it has a hot liquid in it. So you have to pre-charge it. Then you get about an hour to 90 minutes of heating to keep your beverage warm. The way I handle this is that I have the Qi charging coaster on my office desk. I just keep the mug on it at all times. I then will choose my Glowstone whenever I anticipate sitting and reading or working while sipping coffee for about an hour or so because once the battery is gone, the mug just turns into a standard dumb mug. The Ember, on the other hand, should be pre-charged. But it is able to stay on its contact-based charger even while hot. Thus, I can use my ember mug all day long by using the charging base as my coaster. For this reason, I end up using the Ember the vast majority of the time. I have charging bases both in my home office and at work. Ember wins here.Adjustability: The Ember allows you to pick the temp. Glowstone does not. How many people are like me with Ember and actually change the pre-set? I doubt many. Both mugs automatically turn on the heating element when liquid is inside. So unless you anticipate that you are the kind of person who would micromanage the temperature, both are fine here. Honestly, for most people, the Ember Bluetooth thing introduces a level of complexity that probably doesn't help them. Toss-up.Durability: While ceramic is probably more breakable than plastic, I haven't had any problems with breakage on my Glowstone despite regular use over 6 months. I haven't seen any concerns here.

I loved this mug and used it almost daily for 6 months until it stopped working. Of course the return window has long passed but when a coffee mug is this expensive, I expect it to hold up better.

I disliked the fact that it stopped charging after a few months. Definately not worth the money!

Totally worthless. Doesn’t keep coffee hot

It’s a great idea but unfortunately doesn’t work as well as I would hope, for the price. It extends the heat for a bit, which is nice, but this day and age you can spend less on a really great travel mug that keeps your drink both hot or cold for hours. What’s good about this is you can keep it at the office and keep your coffee warm for a bit longer than normal. I don’t have much to say other then, it’s a mug, it keeps your coffee warm for maybe an extra hour, is nice to have at your desk or in your office, but definitely not worth the price!
