Basically, the part is quite handy and works well as provided to it then just (way too early) is broken. With foamy / slippery hands Unfortunately, it goes a little hard to screw up and to. Possibly could have provide a firmer structure or form of here. But that's more of a side note. We have been in the past about 2 years (car wash ...) a total of 6-8 times used. Today when I went to get it out of the basement is (initiated nowhere lid so no pressure on the system was open) when lifting the nozzle from easy. Unfortunately, not just dropped, but canceled. This part does not seem easy to be replaceable by the layman, at least I did not get it unscrewed. Let's see what I now anschaffe me as a replacement. There seems to be little alternative to FM10.
Addendum: Meanwhile, the nozzle get from (my hands were probably a little earlier too wet). So it's changeable, but almost half the cost of the whole product just for the spare nozzle (about 12) I find then something fierce. Ask also how it can happen me that she just breaks through in the middle ...
