Product review (4 stars): Huge improvement, huge pain to install
A huge improvement over our old GE Profile modular cooktop, which (although still functioning) was chipped and worn and looked terrible. Upgrading to this unit was NOT EASY.  We knew there would be ducting issues from other reviews however we also had to upgrade the wiring (30A to 40A).  New cooktop works very well, love power boil and melt feature.  Would love it more if (1) knobs were not in the middle of cooking area, they are always getting dirty (2) fan grate could be put in dishwasher instead of handwash (3) didn't show every little splash and fingerprint (4) was more scratch-resistant.  Am so paranoid about  scratching it that I don't use it as extra countertop space like I did with the old crappy one.
