Product review (5 stars): Nice looking but high maintenance
The installation took me about two hours due to the existing cutout on the marble counter being a tad undersize.  Cutting marble was quite a task.  Once the cutout was properly adjusted, the cooktop dropped in nicely.

It's been about six months of use and we find out that while the cooktop is pretty, it requires a lot of maintenance to keep it clean and it cannot take abuses as the previous low-tech cousin did.
