We love our new Frigidaire slide in cooktop range except for a few scratches that appeared immediately upon using the cooktop after properly applying the recommended cleaner before using.  We are very careful not to move our pans while cooking so as to not cause more scratching, which is a little bit worrisome that we have to be that gentle with the surface.  Other than that, it works great.  Perfect oven temperature and we like having five burners on top.  We would definitely recommend this range for many reasons but do worry a little bit about how the cooking surface will look with continued use.
