I will start at the end:  I love it.  Even though it was not our first induction cooktop, there was still a little learning curve.  But once I learned and understood the differences between this unit and the one I was replacing, it was game on!  Very intuitive controls, and I particularly like (love) the flexibility of the left-side flex zone, the even heating across the cookware (we use All Clad), and the speed boost function.  Beautiful clean design, easy to use, easy to clean, easy to maintain.  Zero second thoughts (other than why did we wait so long?).
Highly recommended, without reservation.
