The castle makes me a pretty safe impression. Nothing is shaky or fragile works. Entering an own distinct code numbers and also setting the correct code turns out to be without any problems.
In the manual accompanying bag, the lock can prima carry. I can not determine rattling!
The only downside is the length of the castle.
Handling is both due to the lack of some length as sometimes tricky.
It's me on several occasions failed to close my bike to a fence or a road sign and could only unite with rear frame. A carrying away of the wheel is thus naturally possible .....
I would recommend the 85cm length.
The castle itself I would rate 5 stars. However, I would continue to buy myself the 85cm Vesion.
