    Signal Protect Silver Film

    Posted by Sharon on 30th Jun 2021

    Love it. It took me about an half hour to install this product on the glass. After its installation, I could feel the difference right away as far as its emf blocking properties. Instructions were well written and easy to follow. I will be purchasing more of this film from this seller.

    Great window protection

    Posted by Valerie Bergquist on 9th Feb 2021

    Great product! I was worried this film would decrease the sunlight in my kitchen, but it didn’t. It’s still bright and sunny- but feels much calmer w the emf protection.
