Why do they cause you problems, Jazz?
Nah not controversial really just differing opinions and experiences.

Mostly for the reasons Doddy mentioned, poor crimps and poorly crimped. But I'm not just talking about Ferrels I've fitted, ( I don't use them anymore, I prefer stranded wires when using terminal blocks) I'm talking about on older machines and esp on Chinese machines when they have been poorly fitted or cheap nasty crimps. Often because of bad crimping or just age they work lose but wire doesn't always pull or fall out and you get false contacts etc, (3 days I wasted tracking a fault down due to a poor crimp.! . . But that's another story.!) Yes I know this can happen with stranded wire breaking but I find it's easier to see and track down.

The reason I don't use them anymore is for several reasons based on my own experience using them on lots of machines.
#1 To crimp correctly and test they are time-consuming
#2 Expense, good quality ones are not cheap and neither is the tool.
#3 When poorly crimped they are difficult to track down.
#4 I lose and drop more of the bastards than I fit.!
#5 I'm lazy..

It's a personal thing so don't stress over it, either way will work.! . . . But don't come back in 6mths time saying got a fault because you know I'll just say TOLD YOU SO. .
