I like my glass top Frigidaire unit. I just use the cleaner for glass top stoves and with a little(real) elbow grease, it sparkles like new.
The old ones are a Pain to clean....but... you don't use them for a countertop either.
And burn things you left on there like we do with the new one.
Just ask me what I think after I drop something on it....
Pro's and cons to everything.
