Lasted three months.  Sometimes the wind blows off the cover, which isn't a problem. This morning there was a huge hole in the middle of the cover, like a giant kid took a bite out of the center of a tortilla.  I touched the fabric slightly, and it started to rip.  I guess it is good if you keep the car in the garage, not so good if you keep the car outside - which is the point of having a car cover. Lame.
