Delta Fluidics H2OKinetics Showerhead

[humid1]

Has anyone tried these? I bought two (thought they were a bit pricey) and have them on the 1.7 gpm setting and found it to be pretty decent. Still trying to convince my wife (why did they put that switch on it to allow 2.5???), but with the water restrictions and price of water/sewer in my area, I'm willing to try anything. That .8 gpm adds up pretty quickly when everyone in the family takes showers.
