Possession of this castle now since May 2014 and can not fault it. It works like on the first day and secures my bike in any situation. However, you should be aware that this castle rather not suitable for very expensive wheels to be mounted in the center a long time. So surely it is not then assess and certainly it also has its weaknesses (basically, it consists of a coated fabric with heavy chain and lock, the chain can be relatively easily cracked with the right tool but).
For my budget bike that stands out in the garden, it is nevertheless a meaningful acquisition and served its purpose. The castle is also not too heavy and also the length is ideal to be able to connect to the bike even to a thicker pile or tree trunk.
I took a few minutes to figure out how to set the numerical code. However, it is out by trial and error and self-explanatory basically.
