Bio Bidet was an easy install with only a crescent wrench and flat head needed.  Fits nicely between toilet seat and toilet.  Seamless integration with my seat.  Had nice flow with no lack of pressure.  Unfortunately after 3 weeks the system started to leak out of the side regulator.  Nothing I could fix.  Good concept but poor construction led to my bathroom floor flooding.  Didn't even bother returning its kind of disgusting at that point.
