These showerheads should be handed out to every house in the country, and be mandatory on new homes. Super-low flow and the special effect of the spray is so good that I am having quicker showers because it feels so gratifying... if that makes sense. I'm def. saving money on water and on power. I have bought a second unit... Fantastic. They seem expensive but are easily the best payback of any effeciency intervention. Best, Ben
