Review on 🚗 High-Reflective White Botocar Student Driver Magnet for Car - Please Be Patient New Driver Sticker, Rookie Novice Driver Magnetic Safety Vehicle Bumper Sign - Honeycomb Reflective Design - 10×3.5in, 3 Pack by John Pound

I wanted this one. The first time we used them I had to wash the car to get them stuck to it. So I thought maybe my car was too dirty. When we got home I took it off and put it in the trunk for next time use. The second time I used them, they curled around the edge a bit here and there, but not around the corner. It's not much more than 70 here, so I'm surprised they made it. They didn't lay flat on the car and I had my fingers crossed they didn't fall off as they didn't hold up very well. The third time, the plastic coating on the front and part of the reflective part begin to separate from the reflective material. I'm still waiting for them to fall off while driving. I was hoping they would last over 2 hours of use on the car.
