Q: Does this plug into the wall socket? In the picture it looks like a USB. Who has a USB at their bathroom sink?!?
A: yes, this is so unnecessary. I wish to have a normal plug, especially for bathroom to have usb to have extra option for water access, I am surprised they want to take that risk for few cents to keepsubmitted byQuality - 1 year ago
