Title: Leaky little devil!
Review: Installed this and it leaked a little above the connection to the shower arm. Reinstalled it and it leaked furiously below the connection where it meets the housing for the filter. Retried a couple of times with not change. It seemed to have loosened up somehow because the unit kept wanting to slide around. I am guessing some cheap part inside gave way when I reinstalled it. I don't think I will buy anything that requires "no tools to install". That seems to be code words for made of cheap flimsy parts!
