I had 4 here earlier this year. 3x 280s and 1 52.
I only managed to adjust 1 satisfactorily
by agricultural I meant simple and cheaply designed, not rough
No Barry I haven't read that. I only have one of the 280's left and its spot on. I don't need to read any more on it.
No point asking provocative questions and getting the hump when responses don't suit.
