My grill is over 15 years old ad this will be the third set of flavorbars I have used. It is the secod replacement set. The first set lastted 10 years and the first replacement set lasted 5 years. These replacements are about the same quality as the first replacement set. They are heavy and well enameled. It is about 30 degrees outside and I am going to break these flavorbars in this afternoon !  Another good product delivered by Amazon and they came fast too.
