  • Works fantastic!
Color: Moonmist Blue
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!

  • Very happy with the purchase
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”. ... show more

  • Short lifespan
Color: Moonmist Blue
It worked perfectly for 2 months. Now nothing. Good expensive charging device.

  • Very attractive, and effective.
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.

  • No more cold coffee or dead cell batteries!
Color: Deep Navy
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.

  • Mug warmer
Color: Moonmist Blue
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!
