We replaced an aging cooktop with this Frigidaire gas model. One of the advantages of this 36” model is the standard cut out size. Many others we looked at would have required a dusty, and costly modification to our counter top. The lighted metal knobs and substantial grates are quality touches. Some reviews noted the higher grate space and claimed a longer time to heat their cookware. I suspect their installer did not adjust the flame intensity or even neglected the regulator and nozzle changes that might have been required for natural gas vs propane use. Our experience has been that this cooktop is quite fast with cook times and, with adjustment, the low settings are excellent. We are very pleased with this unit.
