I bought this Weber Grill, my second in three months, as I needed wheels to get my grill inside at night.  I live near a national park, and wildlife requires my grill to wheel inside at night.  The 4 wheels work well!  My only criticism is that this grill has two puny grill grates be the normal heavy duty Weber Grill grates.  This means less even heating.  This grill needs the traditional Weber grill plates and then it is the awesomeness we expect from Weber.
