First of all this is a very attractive wheel cover that makes my car look great. This means they are very fragile. The design of the adjustable ring, which allows it to fit a variety of rims, leaves a lot to be desired at best. I got my first set on the second wheel, even though I read the instructions and saw the video about it, my hubcap broke. Now, about a month after installing the second set, one of them fell off the car. Very embarrassing and a bit embarrassing. It was like one of those horrible 70's TV shows where the car speeds up and the wheel cover comes off and rolls down the street. When I went after him, he was destroyed. POOH. I've had good luck with Revain on my orders, but this is definitely an exception. I am extremely disappointed.
