$8.99 and works quite well! I was surprised. Kind of complicated to apply but I managed to get it right the first time.

Tips: WATCH THE VIDEO!

Install in the bathroom after a nice steamy shower for optimum dust removal from the air.

Have all your implements laid out and ready to go before you start

Will definitely buy again.
