Congrats on introducing the female 'angle' as it were. A group of male engineer types discussing the merits would tend to completely forget that a huge percentage of toilet visits are by females for no 1 purposes only, and perhaps a light wash followed by a quick blow dry are more than sufficient.

I have tried these in Japan and the first time I hit the squirt button I got a shock-inducing surprise at how accurate they are. It's like they are laser guided or something, such is the accuracy of hitting the target.
