The PowerPulse Massage Hand Held Shower Head is easy to install!  I installed in just a few minutes.  I love all of the power settings especially the massage setting when I am tired from a long day at work.  The hose is great to reach around your entire body or to wash your furbabies.  We have a lot of calcium in our water so the anti-clog feature is a must for our home.  Our teenagers like all the settings to for washing their hair especially.  We are enjoying our new Waterpik PowerPulse which seems to be exactly what we were looking for.
