“I love my glowstone mug. The color is awesome, and once you figure out when to and when no to put the mug back on the pad, you are going to get hot wonderful coffee (or tea) for one hour. The only thing that would make it perfect is to have the heat last longer.”
“On my 5th glow stone. 2 for my bike, one in each car for emergencies and one in the house for dark corners. Just the right size to be indispensable . Brilliant design , quick delivery and good customer service.”
“Very high quality bone china mugs which perform exactly as described to keep drinks hot. Obviously very expensive but that reflects the current market for similar items. One small improvement I would recommend is that the mug heating element be activated as soon as the mug is filled with hot beverage, rather than waiting until it cools as currently designed. This change would make it even more effective in maintaining the temperature, since it obviously takes some time for the heating element in the base to heat the entire contents.”
“The mugs we purchased are first-class. (Great packing...they arrived in the states undamaged.)
But we were really impressed by customer service. We got a courteous response to an email question in a day which was much appreciated.”
“I ordered the mug for a Christmas present. I didn’t expect it to arrive before Christmas because I had left it so late so I was delighted when it arrived three days before. The cup itself is extremely well made and looks great. It also does keep my husband’s coffee hot and you can put it in the dishwasher as long as below 60 degrees wash. An excellent present”
“Beautifully packaged and well presented mug and a nice, simple method of charging. However, even when fully charged, the mug doesn't seem to maintain the temperature of the drink for very long. It does work, but just not as effectively as the Ember mug I also have, which was the same price. For what you get, this is quite an expensive purchase.”
“My wife likes her tea, but she's the kind of person who gets hyper-focused on something and then everything else is forgotten, including various mugs of tea abandoned to go stone cold, even after a reheat (or 3) in the microwave. This infuriates me, so I bought her a self-heating mug. Admittedly I didn't go for Glowstone to begin with, as I hadn't come across them yet. I started with a competitor, which appeared plain and minimalistic but was very gimmicky, and I needed an adaptor to plug it in to charge, an app and a Bluetooth connection. All this to get my absent-minded wife to stick to one cup, and finish it at some point in the day. It quickly lost charge and became a hassle, so I sought a better alternative, and that's when I found Glowstone. British plug, British design and founder, no app needed, no Bluetooth or other requirements, just a cup that heats a beverage to the right temperature until it's empty, and a charging stand that you can use overnight without worrying about overcharging. Just put it there and forget about it till the next cuppa. Perfect!
She was also impressed by the incorporated design of the heating element. You don't see any electronic parts, it looks like pure bone china, even the bottom of it which charges magnetically I assume, so we don't worry about any elements of it deteriorating when washed in water. It's so simple to use that even the most tech-phobic person would appreciate it, and the classic design gives a luxury aspect to it that befits its quality and justifies the price.”
“What a fab product - you don’t have to rush through your morning coffee in 10 min before it gets cold or constantly reheat it, with Glowstone it stays a nice consistent temp while you leisurely enjoy your cuppa. I promise, you’ll never drink your coffee or tea out of any other mug again! I just ordered my second mug (heritage, gorgeous!) after using the first one every day since 2020.”
“I was impressed with Glowstone's delivery as the initial product was miss directed by the shipping company and Glowstone arranged another without any input from me.
The product does what the literature says but the heating is limited and doubt it will keep coffee hot for an hour. Warmish yes. However when you consider the size of the "heating source" I'm not sure my expectation was completely realistic.”
“I have been using the mug for a month and it only seems to keep one cup of tea warm before it needs charging again - which takes a while. I am disappointed that it doesn't heat a few cups before needing to be charged - perhaps I have a faulty mug ?!”
