Mine is finally in bad enough shape to replace, so time to get a new one. I don't even remember how old it is, 5-7 years of constant Texas sun and heat. cold and everything else. It takes the brunt of everything Texas has to offer even the deep freeze of 21. For the most part it is still effective, but on the shelves and in some seams it is startin to show it's age. I am 100% impressed with the quality of these covers and will most definatly extend the life of your grill/smoker!
