These were the first set I ordered, and have been on the car for over two months. I saw a tip online to put your car wax on the back on the magnet before putting it on your car, and make sure it is freshly washed and dust free. I plan on trading in the vehicle in a couple of years, and have ruined finishes with decals, so this was my best bet. I love them, too bad I can't post a photo of probably the only Subaru outback with flames! One caution, if you live in a very hot area, the very thin ends of this particular design may roll up a bit in the sun. My other design doesn't do this. Easy to bend back, but I would just select one of the other designs that aren't so thin at the ends. Very happy, price was right, too, super fast shipping.
