I have had this product for more than a year and it is holding up well. I use this cover 3-4 days a week and after weekly washes. I live in an area with lots of trees and tree sap is usually a problem unless your car is covered. The lid keeps sap or dirt out, which I really appreciate. To clean the lid, I periodically rinse it off if I see a lot of dirt or sap building up and let it dry in the sun. So far there have been no problems. The lid has no visible crack after a full year of use and fits perfectly on my 2017 Mustang GT. I am very happy with it and keep it in the bag that came with it in the trunk.
