The ceramic mug is really beautiful (unlike other self-heating mugs). It has a nice feel in your hands. The mug was a much-appreciated gift, but I don't know yet how well it works. The idea of keeping your beverage warm AND being able to charge your phone on the heating pad is brilliant. Please note that the mug is dishwasher safe, a very nice (and rare) feature.

Bought this for my wife after reading the WIRED review. She absolutely loves it and uses it daily. No more dumped half-cups of cold coffee ten times a day. Now it's always the perfect temp. Bonus that the pad can charge her phone. Dishwasher safe!

It worked perfectly for 2 months. Now nothing. Good expensive charging device.

We’re incredibly happy with this. Aesthetically beautiful, feels good in the hand, the ceramic is a joy and feels more natural than plastic or metal. Easy to clean, but don’t microwave it! Keeps drinks hot but not too hot as advertised. Depends on your preferred temperature, but for us it’s ideal. We’ve expanded to two mugs and their full teapot now, we’re converts. We experimented with a few self warming mugs and this was finally “the one”.

Works well. Only disappointment is that you have to keep it plugged in constantly. I was hoping it was rechargeable so I could place it on my desk without it gobbling one of my USB C slots. Really lovely, and I expected a little more functionality than this.

Really nicely designed; a beautiful glaze, and shape of the cup and the 'water-formed stone' shape of the base is really pleasing. A gift for my wife- she loves it. Very high quality workmanship. And after your cuppa, charge up that phone- so very conveniently; has a permanent spot on her worktable.

This is my second time purchasing this mug. This version is more current and works far better than the first. This will keep your coffee warm until the last sip is left. I absolutely love it!
