I do not know how many stars would be true .....

- 5 stars for the optics that gives the impression => this is a thick chain, so hard to crack.
- 4 stars because the lock is difficult (on multi-day tours with luggage I do not take it with) - but difficult such a product has to be well, so it is difficult to crack - so that it can complicate a theft seriously.
- After a few of the other reviews 0 Sterrne because of the impression of the security probably deceptive.
- 1 star, so that the review by the Amazon system is assumed.
My conclusion: It's up to me most in the garage. The times I had with the castle, I have never lost my precious longer wheel out of sight.
