We've had this cook top installed for a month and it works exactly as hoped. We are still getting used to how quickly induction heats and how hot it can get, but overall, it's such an amazing change switching from traditional electric to this. We'd been warned about how easily dutch ovens can scratch the glass surface and I did purchase teflon burner covers to try to protect it, but even when we haven't used the covers, I haven't noticed scratching. It is a bit noisy when operating, it sounds like fans blowing and can be a little high-pitched, but it's not really that big of a deal to me. I really love this cooktop. He had ours custom painted to match our oven and dishwasher for a 1960's look.
