I have this stove just about a year and I am on my second cooktop. The first cooktop seem to scratch just sliding a pot to the side. Then it seemed that the spots were becoming deeper gouges. I have the correct pots to use on this cooktop as I had a least expensive cooktop of another brand for close to 10 years that I maintained perfectly and it never scratched. This expensive stove has an incredibly high maintenance cooktop that I stress every night when I need to clean it, just unbelievable. I am doing everything possible to maintain this second cooktop scratch free, I feel like I’m walking on eggshells every night when I cook! Very stressful!!! There needs to be an improvement on the design of this cooktop. I would have thought twice about purchasing this grouping of products if I knew this was going to be a problem.
