Works when nothing else does!
I have hard water where I live and have developed brown rings around my toilet.  It's pretty gross and embarrassing when I have people over.  I have tried every product, numerous cleaners, sprays, etc.  Nothing worked.  I saw this product advertised on some pop up add (or something like that).  I did some research  and chose this particular brand based on the reviews.  I was not disappointed!  I used for the first time and toilets look like new!  I did have to use a little elbow grease, but just scrubbed for about 15 minutes.  Handle works great.  Some of the stone does rub off, so in one use I used about 3/4 of the stone.  This product comes with 2 in a pack.  I plan to use this every few weeks now as a preventative measure.  I can't believe how clean my toilets are now!  Very pleased with this product!!!
