Locks that work

oh yeah i'm not arguing that the two yellow locks are different locks i was just pointing out that you can't tell which is which by the colour because the abus 40 which is normally red also comes in yellow like the more secure abus 401

This is correct, I bought a yellow (coloured) Abus Mini off Decathlon a while back which is the cheaper silver-rated version. See my post (and munchbunch313's) on page 2 of the secondary locks thread.
