Product review (4 stars): Looks okay, for the price...
I asked customers who bought this item whether it comes with any rubber gasket and has been replied with "yes" (rubber one for above and fiber one for below the sink).  I just received the item today.  There's nothing else beside the flange itself!  Though it doesn't cost much to buy gaskets for it, I'm still a bit disappointed...  It looks acceptable, but time will tell whether the finish will last long or not...
