I bought a new performer deluxe grill to replace my old Weber that was 16 years old and had rusted out. The new grill lives up to its name with many nice enhancements including the charcoal bin. However the supplied grill cover is a big disappointment. The first thing I noticed is it is much thinner. With a decent gust of wind it will blow right off the grill! (I have to use a brick to weigh it down.) Additionally, and to my surprise it is not waterproof like the old one. When I take the cover off after any rainstorm the grill is wet!!  This has never happened before with the old grill cover. Weber, this is not the quality I have come to expect in you. You have really cheapened the grill cover in a big way! Great grill, lousy cover. Fix it!!
