Product review (1 stars): Enormous disappointment for price
Pros:
1.  This cooktop generally performs well.
2.  Look like a high tech and restaurant style cooktop when installed
2.  The electronic igniters do a good job on repeatedly lighting the flames, with consistency and regulating the flames.
3.  LED lights illuminate the base of each control knob when the flame for a burner is on.  This is a nice feature to let you know if any of the burners are on.

Cons:
1.  The thickness of the stainless steel base is not very thick and does not appear to have the hardness, required to resist scratches and dents that come from general cleaning with scourers and dropping the occasional kitchen implements.  Also, the cast iron grates do not have any protection on their footings to protect the stainless steel base from being scratched when removed and replaced for cleaning.  It is impossible to keep the stainless base from scratching and maintaining a clean pristine finish.  The cooktop looked aged within a 3 months of use.  An enormous disappointment.

2.  The controls all had different degrees of play and resistance.  Some would turn very easily, other had a high level of resistance.  Also, most of them had up to 0.5cm of loose play from their central spindle.  The extent of play got worse with daily use.  This gave the impression that handles were fragile and constructed of poor quality.

3.  The numbering and lettering for the flame control is of a small font size and not easy to read if you have poor eyesight.  More disappointing was the ease by which the numbering and lettering eventually disappointed with customary cleaning.

4.  The cast iron grates sit too high above the burners, causing a significant time for cooking pans to reach temperature.  The burners were never able to achieve the high temperatures needed to sear meats or make stir fries.  Getting 1 gallon pot of water took over 7 minutes and it took almost 15 minutes to return to boiling, after pasta was added.

5.  The flat cast iron griddle is a great idea, but it is impossible to swap it in and out on a regular basis without scratching the stainless steel base.  The cast iron griddle had recess on one side that was intended to collect drippings and juices from the food for cooking.  The recess was insufficiently deep to collect the juices and would easily overflow.  Also, the griddle did not have a sufficient gradient to force the flow of juices into the recess.  The height above the flame and thickness of the flat cast iron griddle caused the griddle to take a long to heat up and would never reach to necessary temperature to sear steaks

6.  The LED illumination of each control knob is of insufficient intensity to be useful.  The illumination is difficult to see under the lights of a rangehood and from a distance.

Overall:  I ranked this cooktop with the lowest possible rating and is a significant disappointment, relative to its premium price.  This cooktop is constructed with poor quality materials, fragile, cannot withstand even the mildest of wear that comes with general use, and does not achieve the necessary temperatures for cooking.
