Product review (5 stars): Works as advertised and looks good.
This unit replaced an old Jenn-Air cooktop.  The cutout for the Jenn-Air was a bit larger front to back than for this unit.  So I had to do a bit of creative patching.  But once installed, the only issue was getting the gas line hooked up.  My existing gas line had different threads.  A trip to Home Depot to buy a new one -- you're supposed to always use a new one with a new installation anyway -- solved that problem.  The unit comes with three different gas line adaptors and one of them fit.  After gas was hooked up and electric plugged in, and all the fixtures up on top  put in their places, it came alive.  Five beautiful gas burners, including a double ring in the center, all with the right pressure and good blue color, with instant ignition when you press down on the key.  Very nice to look at.  Should be easy to clean.  So far, so good.
