    Kinda not great.

    I love this for cooking but after just 7 months, the indicator for which burner is for which knob has come off around all knobs. The inside of the stainless cooktop area has rust showing in places. I read not to use abrasive, only mild dishsoap and water. I have only used a soft cloth and dishsoap in warm water to clean, I clean it daily when we are done cooking. The grates are wonderful and look like they will last a lifetime but the rest is pretty much junk. It’s sad because it was very expensive. I called and they will have me call a local rep to come out and check it. They might replace it but I don’t know if I want this junk again.

    Basic gas cooktop

    Replaced a 20 year old DCS gas cooktop whose electric ignition was flaking out. In hindsight, I should've kept it and disconnected the electrical - since it flakey - and continue to use a lighter or match. This is a basic cooktop - the grates, covers stained easier than expected. The catch basin is a fairly lightweight stamped steel. Lighter than the 20 year old DCS. The grates are asymmetric.
