Product review (3 stars): Electrolux ICON E36GC70SS gas cooktop
This is a beautiful cooktop and compliments any kitchen.  It is well made and cooks with precision control.  The deep set sump catches spills and cleans up with ease.  I have it converted to LP and it operates flawlessly. I often use it to can vegetables so the top often carries a heavy load.  My one complaint is the knobs.  They are plastic and break easily.  I have not melted any of the knobs but all 5 have broken and are hanging on with tape and glue.  Considering the cost of the unit the knobs should have been made of stainless steel.  I would have awarded 5 stars to this unit if the knobs were not so flimsy.  I will not replace the unit with an Electrolux.
