Locks that work

No. The lock isn't compromised in any way. The orange part is just covering the narrow part where the mounting bracket usually is.

Yea, and I was thinking that this rubber/plastic material is easier to cut through than the (metal) mounting bracket!

And it's cheaper than the normal one.

Ah, good for people in the states - over here it's €40 for the 'normal' one and €50 for the red one...
