I have been a big fan of Weber Kettles for over 40 years; this is our third Performer. I was excited at the many 'improvements'; a heavier cooking grill, better timer, better thermometer, larger ash catcher, higher quality wheels, etc.  
Unfortunately there are flaws:
-The ash sweeper arms angle up, and do not seal the vents; the fire is never extinguished. 
-The gas line and regulator needed to be replaced.
-The table has a very slick surface; plates can slide off.
-It is tricky to correctly position the cooking grill on its bracket under the bolts for the 'hide away' lid once the coals are burning. 
-It is almost impossible to replace the ash can after removing to empty the ashes. 

I'm still a big fan of Weber, but this experience has been disappointing.
