Basics
The PhotoShield is a license plate cover that distorts the numbers of your licens plate if you look at it from the side or above. From straight on it appears to be a run of the mill license plate cover. The idea is that red light cameras and speed trap cameras, which are usually situated above or to the side of the road can't take a clear picture of a license plate, therefore making it impossible to get a ticket.
How I Tested It
Obviously I wasn't going to slap it on and intentionally run red lights to see if I'd get tickets. So what I did is install the PhotoShield on my license plate, then took looked at my license plate to see if it really became illegible.
Pro's
The PhotoShield really distorts the numbers and letters on any license plate when looked at from the side or above. I can see why the creators claim that it will stop 90% of all speed trap or red light tickets.
Con's
The PhotoShield has some drawbacks, though. It can't protect against all red light or speed trap cameras. If the camera is situated at the right angle, then you'll get nailed all the same. I also didn't like the fact that it always distorts your plate. It could cause some potential grief from cops. The law says that your license plate has to be clearly visible from the naked eye. This isn't always the case if you look at a plate covered with a PhotoShield from the side.
Overview
I honestly wouldn't recomment the PhotoShield. It seems to be a little unpractical. Instead, I'd recommend PhantomPlate Reflector Cover or PhantomPlate Reflector Cover. They seem to be more effective and practical to me.
