Hazardous screws make rain stick to scrap Goods

The rain stick is optically correct, even the sound of many metal beads is pleasant. However, the screws holding the housing is mounted at the ends, are absolutely inferior and totally inappropriate for a small children's toys. The edges of the cross slot all four screws are incredibly sharp and are starting to shreds from the bolt. I have never come across such a screw in normal household use and I wonder, where the manufacturer has here and how he can handle such a serious scrap for toys. In addition, two of the four screws are very poorly finished: they were inclined screwed through the plastic case, so that it has been damaged by the screws and also forms small, sharp scraps around the screw. I myself have read the only previous -Also negative-customer review prior to my purchase, but thought, so bad it is not even his; this was a fallacy: of this product is strongly discouraged !!! Not for children!
