Great original idea, but not perfect
The mug is really cool looking, and changes colors instantly. But you can still see a very obvious residue of the opposite color. Definitely not like the pictures shown. I'm going to contact seller and update review with the outcome.
Vendor just contacted me and informed me that the actual technique will not allow for the colors to change the way they are depicted on the pictures.
