Clearly the rolling stones did not understand statisfaction

..I’m with Roy. Wherever I see these type of crimp connectors (and wretched Scotch type) I bloody sigh and just cut them off / re terminate the wire with quality crimps..... because in all my experience they are just trouble.
Before this thread I honestly didn’t know that you could actually crimp these connectors reliably .... you live and learn.

(But I won’t be changing, even if can be crimped ok they kinda look very DIY & naff!)

Have to agree with the above. Always get the impression, wrongly or rightly, that the wiring has been hacked about and this raises the question of maybe other less obvious horrors.

The main problem with them is that even if the crimp is good you can't tell so every connector is a gamble. Even with uninsulated crimps and the correct tool you still get the odd bad one but you can see it and do it again. Each to there own but from my experience those things are trouble.
