The cooktop and the convection oven work great. Good control over temperature, and speed of the boil is remarkable.  What I think could be better is if the cooktop was entirely the black glass surface and did not have the rubber gasket at the front. It’s constantly catching crumbs and pops up several times a week. I’ve only had the range for a month and I worry it won’t last.  There is another crumb trap at the back of the cook top that I wish wasn’t there.  The range is also an inch higher overall than standard counter height and the installation isn’t as streamlined as it could be.
