Security rating
The security rating helps you choose the lock that is most suited to your needs. For this reason, B'TWIN defined a test protocol with an independent laboratory, CNPP, based on real-life theft techniques. This unique protocol allows each lock to be given a comparable rating from 0 to 10 indicating how theft resistant it is.
Hundreds of different keys to limit the risk of theft. Comes with 2 numbered keys.

Excellent product
Used for 2 to 8 weeks
Highly recommended
Key snapped too thin
Used for 1 week or less
I have a Decathlon cable lock which was cheaper and has a fairly solid key. This however has a very thin key. As a result the key bent and snapped off in the lock on the second use.

Total ripoff
