I waited a long time for my new cooktop. Overall I’m very happy with it. However I do have a couple of suggestions. One is what I consider a design flaw. The knobs stick up further than the grates. You have to be very careful not to slide pans over them because the finish on the knobs scratch very easily. Shorten the knobs. The second is about the instructions for install. It doesn’t mention that the gas supply is very specific to each burner and once you find that out, you will need a magnifying glass to read the necessary codes. Just put it in the instructions. But again, I’m happy with it.
