I was tired of replacing shower heads find every one I got to replace the old ones due to mold were more and more water restricted. I am not a Amazon employee or reviewer, but must say, I just took the best shower in 20 years. I think you use less water with full pressure and flow than with the restricted ones. But anyway, if you want full flow and pressure try this. Got away with it by including a regulator that you don't need to install.
