After the confusion "only wall mounting": first attempt to start: a jet in our bathroom! Trying to keep the part in the amount in order to reduce the volume (wall mounting!): West Runway. Very unpleasant noise, howling, strident. "The operation is in rented accommodation after 22 clock is not recommended." (This note is missing in the instruction manual.)
Second attempt: Function Test: rippling Wasserstrählchen at the highest setting level (MAX).
I beg your pardon?
Instruction manual!
Third attempt: "adjustability of the nozzle for stronger water jet": How and Where? Eyeglass wearers: Remote glasses - Farsighted: Reading glasses on. Both: Lupe use - third hand. Tiny points formations on the nozzle head showing something to: aha - the adjustability.
Fourth test: adjusting some tiny thing not shifted his will. Super fiddly, difficult to move.
Fifth test: with the other setting, bland murmur, small jet, nothing to see of pulsation.
Conclusion.
Inadvisable. If only because of the incredible noise. And of course because of the complete lack of function.
Fortunately, there are reliable unwinding at amazon.
