Product review (5 stars): Induction Cooktop
Cooktop was a replacement for a Sears branded radiant cooktop.  Cutout dimensions were exact so it dropped in with no modifications.  Unit removed was a 4wire where this one was a 3wire hookup but using instructions, no issues on installation.  After a couple of months, unit has been great.  Had to buy a few more induction capable pots and pans.  It is amazing how fast unit will heat up cookware and just as fast to turn off the heat. You can clean up spatters surround the cookware while cooking since cooktop doesn't heat up and just as easily clean off the 'burner' once the pan is removed.  Since cooktop does not get extremely hot, spills do not get baked on so cleanup is so easy compared to old radiant heat cooktop.
