Product review (5 stars): Very pleased
I finally got this installed - um, it is realllly heavy - so have help!  Once you attach the downdraft fan - it is super heavy.  The fan is super powerful, that is really nice, keeps the cooking area cleared and no obnoxious overhead venting needed.  I love the power boil setting.  I didn't really realize all the nice features of this when I picked it out, I just knew the size I needed and that I had to have a downdraft, then price and overall star reviews came into play, and I made my choice.  I was switching over from a propane cooktop that was not working well, and was thrilled that my electrician was able to do all the disconnects and hookups needed. He was even impressed by the cooktop.  It looks really nice and it seats firmly in position.  A reminder- the counter mount is optional and does not come included.  There is no shifting or movement.
