Works Great, forget the hand piece
I do not have Dr. Mercola's BUT i do own an Aqua Sauna filter.  The filter works great.  Set up and installation are normal considering you are working with water under pressure!  It took a longer while than the directions said to flush the beads during installation but no biggie! The reviews on the &#34;hand wand&#34; are correct that part is a piece of crap and breaks so just buy  the base unit and add your OWN shower head!  I have had mine for a year and it has worked great for the whole year. (of course it is past time to replace it).  I would absolutely purchase the same filter again!  (lost a star over the hand piece)
