I have had my PGP9030 for 1 week.  Love the control available to the burners.  In fact they are so ht I haven't even cooked on high.  On the flip side the grates are already warping which is a disappointment.  Also the grates are very tall compared to my previous cook top.  Easy to clean except around all the buttons.  I slid a cookie sheet onto the grates and a button got scratched, so the buttons are too tall in my opinion.  They should be shorter than the grates to avoid this.  Overall I am pleased but I may be just pleased because my old cook top was really bad.
