Got this to make things more comfortable for my husband after chemotherapy and the extreme tenderness it causes. Easy for me to install, took about 30 minutes from shut-off to turn on. Clear, step by step instructions. was able to hand tighten everything without leaks...it's been a few days, still no leaks. Control is easy to access on right side and clearly marked, Don't need to look as it. clicks off in center position. Forward turn to front wash, back to rear. Flow is gentle, like a drinking fountain. Husband is pleased.
