The build quality is also good. Until now I had unfortunately just peeled off a tunnel defect in which to me is in fact wearing the paint in the ear, that of course should not happen, but it was as I said just a single one.
The mentioned problem that tilt both sides screwed attachments, I did not: It can be seen by itself as it is well screwed.
All in all I would still useable give 5 stars, in retrospect, I would just not again take Dehnschnecken because I had some black worm, I could keep this bad deal and had accordingly raise issues to make the matching variables identify because you will not ( can measure it as rods).
