I needed the bathroom door a double towel bar that not screwed into the door, but is hooked. Well, this Zeck they met, but the support bands for the actual rods were not fully abgegrated and partially razor sharp. In order not abzuhobeln the door when pushing the double towel bar me (otherwise I would have drilling can) I felt 'stuck underneath and filed at the points that come into contact with fingers, even the sharp edges. As it hung then, it was moved, but so flexible that I could fix it. For better quality, I would have paid more.
Conclusion: good idea, clear design, poor workmanship, partly not roadworthy, so only ** star
