Not very happy.  In general the burners are not fully adjustable from the max rating down to a simmer.  Even the smallest burner when cut down low seriously boils water.  Impossible to simmer anything.  Also some of the igniters seem to randomly start sparking even after a burner has been on for a while.  Also the ignitor for the triple crown burner will not stop sparking.  A nice service rep at Fagor is working on getting that fixed.  Also I had to buy the gas pressure valve from Fagor because it was not in the box even though the instructions say that it is included.  Generally not happy with the unit.  May just bite the bullet and buy another brand.
