I like that this showerhead saves water 2 ways- by being low flow and by shutting off when the water is hot enough to jump in. Rather than stick my hand in a few times, I just let it run until it shifts to a trickle, then pull the switch, turn on the cold and go! I bought one as a test about a year ago and having used it regularly during that time, bought 2 more. It's not annoyingly spitty like some cheap low-flow heads, and has a big, solid look to it, further improving on the old crappy low flows. I'm constantly amazed that this is actually more frugal with water than many other crappy "eco" showerheads.
