it's ok. i'll get use to the lower pressure. my wife isn't thrilled with it, but it does have a neat 'water pause' feature. I expected that it just stopped the water flow (mainly to keep your settings w/o turning everything off, and back on, while you lather, wash your hair, whatever), but it just cuts the water flow in ~ 1/2. It's a button on the handle itself you can press.
My biggest 'waste' (and why i have the hose, not just a straight nozzle) is i can't stand the cold water hitting me, so i pull the shower nozzle down, let it warm up, then put it back up.
