Product review (4 stars): Great but hard to clean.
This stove top looks beautiful and heats up quickly.  I love the griddle option where two of the left burners can combine to make one long heated area great for a pancake griddle.  It arrived in two days and the price was $40 less than anything else I could find on line, or by calling various appliance shops.  With Amazon Prime, I paid zero for shipping!  My only issue with it is that it's very difficult to get a streak free clean on the glass.  The knobs are tricky to get around to clean as well.  This cook top is on an island in the middle of my kitchen so it's sort of a focal point.  I guess I'm obsessed with it staying perfectly clean.  The best solution so far has been a squirt bottle filled 3/4 with water and 1/4 white vinegar.  I added a little squirt of dish soap as well.  Spraying this on it and wiping down with dry paper towels has worked best.  The cleaner they give you with the stove just ended up in a big streaky mess.  I'm regretting that I did not buy the version without knobs.  The fan is a bit loud on high, but not bad at the lower speeds.
