I installed in it 20 minutes with my bare hands and a nail file in lieu of a screwdriver for the holster. I may attach it to the wall later since the hose touches the floor. No leaks, and good pressure. I just have to remember to turn off the valve after every use. I would buy another but I’m  waiting until a better sale. After five years in Turkey, I really missed these wonderful devices. Yay for better hygiene down there!
