Locks

Has anyone heard of one of these Abus locks being defeated?

I use one as a courier and mine has been attacked with cutters - only went through the plastic cover and left a puny scratch. I'm about to start using a nicer bike and wondered if I was using a good enough lock..? Experiences? Rumours? Ta.

i've had this lock for over 10 years of couriering and domestic use and it still works fine. its got all sorts of nibble marks on it from skidders trying to steal my bike but no one has had any luck. i recommend this lock to everyone.

Also, one time some guys broke into our back yard and stole all the bikes there except my one... although to be fair it didn't stop them stealing everything off the frame. nothing worse than seeing your bike looking like a picked over chicken carcass.
