as I had the spare heads as ordered stock, I unfortunately could see yesterday that the replacement heads do not fit properly. They must be under enormous pressure put on the body and then she gets almost no wiedr down, also you can do not tighten, which would ansich not necessary because they clamp eh, but the result is Zwichenraum is ideal for seed collection. I can return it so after so long no longer, I'll try it one last time and order new spare heads, I'm curious.
