The carrier for the transport is also OK, the mounting possibility with Velcro straps or to the bottle cages is convenient. Only the closing of the bracket with inserted lock is a little hard and tiring, here you could find a nicer solution than this plastic tab with the Plastikhäckchen. You have to pretty pull to get the flap is long enough and the durability of the tick is probably rather low.
Conceptually, this type of course castle has a few drawbacks that could cause I would not buy the castle again. Mainly it is the effort in completing the bother. You have to remove the lock from the mount, open, unfold and carry out the "snake" through the wheel frame and possibly the object to which you connect it. The latter is not so easy, because by the folding mechanism, it can lead not always clean, and it has of course the urge kinking with gravity down. If you have it then carried out and want it close then it often happens that an obstacle almost exactly in the middle of a folding element comes to lie and not at the crease - this increases the usable length or it begins a fumbling at the lock shortened align so the it bends low and to an adequate enough length.
This effort "worth" of course only if you park the bike for longer time. Only to quickly get bread at the bakery, I am inclined to then but to dispense with the protection and to keep the wheel for this time possible from the shop in mind.
