The stoppers are good, serve their purpose, see decent Done. The only point that makes me come here to a deduction of a point is the packaging, because the weight of the stopper, the cardboard packaging completely disassembled proverbial, so that the consignment in the DHL hub was rejected, had to be repackaged and therefore correspondingly delayed arrived. That can always happen, alright, but if I lift up the 4 things, then I must be clear that a thin cardboard cover gives up the ghost immediately. That would be annoying to me but it is clear that this has nothing to do with the product, so I give it 5 * then J
