I have had a lot of covers over the years, but this one at first glance seems to be better than most.  I just bought a new Weber grill, but Weber grill covers are just garbage.  They become brittle after about one season and don't even fit the grill well.  This one makes it easy to take on and off, looks exactly as pictured and appears to made of better quality materials.  Time will eventually tell, but one thing I do know is I can't imagine any product being worse that what Weber sells for their own grills.
