Product review (2 stars): Don't buy Fagor gas cooktop if you want to simmer
I have the 36" 5 burner gas Fagor cooktop.  It is no longer the current model, but other than looks, is about the same. I bought the older model because of the issue in the other reviews about the grates being too open and pots not sitting straight.. So that is not my issue, BUT I do have a serious issue. None of the burners will even come close to simmering anything.  In other words they will not go low enough.  Customer support does not have an answer and referred me to the service department.  Get this.  They told me to use a " flame tamer" because there was no way to reduce the heat except with the control knob on top.  On their website it says their triple crown burner is powerful and yet can be turned down to simmer delicate sauces.  NO WAY. On its lowest setting all 3 fire rings continue to burn which translates to boil NOT SIMMER.  Even the smallest burner will not reduce to a simmer. I wish I had bought another brand.  Bob
