Amazon strips the 16 strips are cut into 3 strips resulting in 48 strips. I remove the strips after each trip. My July trip drive from Columbus, Ohio to the NY Hudson Valley thru Pennsylvania and NJ did not result in any double charges. I did not register the plate to my NY EZ Pass. My tolls for the trip were approximately $120.

I left the pass attached to the windshield below the rental car box. I have a scraper in my keychain which makes removal easy. I removed the pass when parking in NYC at the Yankees game.
