Guys, not to scare but beware putting the smart tag holder on your windscreen, as these smart crooks nowadays are smart enough to think that there is a smart tag in your car when they see the smart tag holder on your windscreen, and smashes your window to get it from your glove box. Even if your smart tag is in not your car, you might end up with a broken window.

Happened to my brother once, just sharing. IMO, safer to just put it on a non-stick mat or just hold it.
