Incomprehensible good reviews so far ...

Conclusion after just one month use:
- Rust stains
- Heavily worn carabiners

Va because of the last point has become unusable because the dog then can walk around including linen and may impose the leash. These lines are definitely not designed to 50kg because my DSH weighs about 40kg.

I'm very disappointed and would advise everyone from buying, rather spend a few more times instead of two buy.
