"Can I use regular cleaning supplies on the mirror?"
Yes. You can use any normal glass cleaners and mirrors cleaners to clean these wonderful fogless mirrors. Since the mirror is heated, don't use combustible or toxic substances.

"Can I install the Clear Mirror horizontally?"
Yes. If you would like a wider view, maybe for two people to share at once, feel free to. You need to alter the installation directions yourself, paying close attention to the Clear Mirror height, sink centering, and the cutout location.

"Since the fogless ClearMirror uses an electrical heating pad to warm the glass, is there a chance I can suffer an electrical shock?"
The fog free Clear Shower Mirror is Underwriter Laboratories (UL) and C-UL listed, tested to the CSA interantional standards. The low voltage ensures electrical shock cannot happen.

"If I didn't place the adhesive heater squarely on the back of the mirror, can I pull it off and re-stick the pad?"
The heating pad has been designed to be very sticky. If you attempt to remove the pad, it will probably get ruined.
