I`ve used them several times and find them very good.
So good in fact that when I wanted to do a "painting by numbers" type diagram for a friend wiring his downlights I`d recommended those Click connectors to make things easy for removal of luminaires to add/alter/test.
So I printed the pic and started to write on it as a reminder for him, then I looked and thought "Hmmm, slightly wrong". I ignored the lack of colour ID correction initially, then thought "well, most of us I think would make Brown (Red) the loop and Blue (Black) the SW and put a bit of ID sleeve on it but then I thought "No still not right!".
Anyway I`ve emailed TLC and I`m sure they`ll correct it in due course.
No doubt they`ll be happy that contractors look at their site and being mentioned on this forum will do them more good than harm.
Two other "Clasics" on websites spring to mind :-
1/ The Part P Gov early days one showing a mainstester screwdriver next to a 13A socket as if to tighten the terminals (Neon tester a no no and blade too small anyway).
2/ That pic of bath zones showing a zone around a hand basin as if to exist in regs-land . That one got copied on loadsa websites too
