I purchased the S-420 sometime between 2008 /2010 and have used it continuously since.
It has performed without a hitch, grille looks brand new, of course I clean it  after each use and every other time wipe it down  (on the outside) with WD-40 ... the only problem after all these years is the starter for the side burner, which is no real problem ... why would I send in a review after all these years, well, it's because I read the reviews tonight for the Weber S-470 and wanted to let Weber and it's customers know that my grille is still doing it's job and looks almost new. I was going to get another grille but I think I'll keep this one, it's been faithful and keeps our family happy.  V/R  submitted
