German quality. The pommel is provided with small holes arranged in the form of rings. There are four jet positions. The fourth all rings are used, the jet is large with plenty of water but it is very soft. On the first position only the two central rings are open, so jet narrower, less water but more pungent. The other two are intermediate. The jet has always more or less the same shape, there is a difference in width, water quantity and intensity, other knobs offer varying forms jets (three massage jets, rain , central laminar flow, etc.) but not here. This mode is fine. The transition from one level to another is done easily, without forcing, with good click every time.
