I like the product and agree with the positives of other reviews.  Here are my installation comments.  Manual is weak.  It should be written from watching 25 people  try to install it and it cover more of the details of install issues.  Reverse threads on the tank connector, etc.  As you kneeling in front of toilet that even just cleaned up, still is a toilet in your face, no fun and rather demeaning.  A video would be great but did not see link.  There needs to a site where users can upload their own installs, think it would be positive.  The actual attachment looks like a kluge install...sure PD is aware and 2.0 will be better.  I know hitting the product ship date was huge and fast tracked some areas.

The bottom line is that my home will be 90% paperless with minimal expense!
