One thing is I find that it's really water pressure dependent. At least with the class of no-frills, not-expensive toilet attachment ones I buy.

I moved recently and at the new house water pressure overall is noticably lower and it's far more difficult and slightly frustrating. If I hadn't learned/trained/experinced on higher water pressure I probably would agree with your assessment.

yeah if you accidentally put the dial a bit too high it will hurt on one that will clean properly.
