Search this thread, they've been discussed previously. I think they're decent locks and represent Abus quality quite well. They're not a really hefty primary lock, but since they have the advantages of small size (less room for tools) I think 2 of them would deter attacks on a cheapish bike and defeat casual-to-moderate attacks. They are quite small though, good with tight clearances, useless on an mtb.

Edit: Apologies, the actual discussion of these was in the Secondary Locks thread
