Product review (4 stars): So far, so good.
I was a bit nervous to order this.  I've had some bad luck with GE appliances and mostly use
Whirlpool and Kenmore now.  But my wife and I wanted a black downdraft 30" gas cooktop and options were limited.
So far, we very happy with it.  It does show spots (just like a black car), but it can be cleaned up or you can just
ignore the spots (like I try to.)

My only real complaint is how the downdraft connects.  It's a 3.25" x 10" rectangle that you can adapt to a 6" pipe,
but I didn't have enough room to do this easily for my install.  Ended up needing quite a bit of flex pipe to loop around
an connect.  When the downdraft fan is turned on to the max, it does mess with the flame, but on low,
it did a good job of venting the bacon smell to the outside.  Normally, we don't use the downdraft since
we mostly cook eggs, beans, veggies, etc.

We've had it installed for about 3 weeks now and so far, it lights nicely.
