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
