I had an induction cooktop in my last home, so I was excited to replace the radiant cooktop in my new house with this unit.  It works as expected.  It isn't too loud and I haven't had any issues at this time. 
It seems to require a higher setting than my last couple of cooktops for the same heat.  So where the radiant cooktop would be on a 4, this will be on a 6.  I don't find the settings between 1-4 all that useful.  It would have been nice for the 5-9 settings to be smaller variations than 1-4, as you are generally just keeping things warm on the low settings.  5 would be the standard medium on most cooktops, but I find it a bit underpowered on this one, so I do most of my cooking on 6.
