I bought this gas cooktop and was installed Aug 12, 2020.  I like the cooking, however the interior was scratched out of the box and one of the knobs is scratched and I am very careful,  Don't know how that happened.  I like it other than the scratching.  For a professional cooktop this shouldn't happen.  My griddle was damaged in the box.  Frigidaire needs to look at their product and redesign so scratching of knobs is not a problem.  I'm bummed my new cooktop already is damaged.
