It only works for a few months, then you have to wait a month for them to replace it with a new piece
already advertised 2 times
apparently it has some kind of design flaw, it stops spraying water every time (probably a broken pump) even if you regularly clean it with a solution for oral showers
it stopped working after two months. the complaint took 28 days to process. in the meantime I had to buy another one
