Those hand sprayer versions are bad to use and unhygienic too, because fecal matter gets sprayed beyond the toilet bowl. I know why Arabic countries prefer hand sprayer versions: istinja practices of Islam.
Not with the one I bought at Home Depot. Two valves: one with a longish lever at the bottom of the tank, one in the sprayer, one at the wand. Use the first lever as high-precision pressure control, the one at the wand as a quick cutoff or not at all.
Adjust pressure to a 3-4 inch high fountain. No overspray.
Angle the flow forward, to minimize drip-back onto the sprayer head.
I have been using Neo180 manual bidet for 5 years, which I bought for Amazon. Replaced it last year with the same model. I don't like manual handheld sprayer bidets, which are popular in the Middle East; later, they spread to SE Asia, now South Asia, Russia.
I used it in Indian hotels. Sure, one should get 30 day practical course on how to use bidet spray without wetting the whole restroom, without spraying junk around. If that is what initiation is, it is a failure in my considered opinion.
How does one get initiated? They had the hand sprayers at my office in India. I never tried. Experimenting with that and having to go back to work seemed like a bad idea. I also didn’t feel like asking co-workers how to use their toilets.
Well, Indians have learned this technology from abroad--mostly Middle East, thats where many Indians work. Of course, now Indian companies make those sprayer bidets.
Squat toils + bidet attachment is better than squat toilet and a jug for water. No dispute about that. Sit down toilet + hand held bidet attachment is worse than sit down toilet + bidet inside in the toilet without using hand. My answer was about sit down toilet with hand held bidet attachments; how Indians discovered these hand held bidet attachments.
