Review on BOKA Student Driver Car Magnet, Thick Double Magnet Student Driver Signs for Car, Enhanced Magnetic Please Be Patient New Driver Safety Bumper Sticker for Novice Teen Rookie Driver (Upgraded for Better SEO) by Jay Ngo

Great! They are highly reflective and can be easily seen/noticed by other drivers. They stick well to the car and are easy to remove by hand without leaving any marks. They are advertised as thicker than others but I have no way of comparing as I only bought these. They seem to think enough to last and stay attached to the car for as long as I need them. Warning: Make sure you have a *metal* part of your car that you want to attach them to. Many cars today can be plastic or composite. I tried gluing them to my (plastic) bumper but it didn't work that well. Luckily there were pieces of metal in the back of my tailgate big enough for the magnetic signs, so that's fine.
