Luckily my radiant cooktop stopped working and I was able to switch to an induction one.  I love that it heats up instantly for boiling water.  There is excellent control when bringing rice to a boil and then simmering it.  No more boiling over onto the cooktop.  I usually clean it each evening after use with Weiman.  The trick to making it streak free is using a dry paper towel to polish it off.  It does scratch easily.  The problem with the sync feature is that the griddle does not heat all the way to the edges, hence the pancakes do not evenly cook. Overall, it is a pleasure to cook on this induction cooktop.
