First of all: the product itself, I am very satisfied. The invoice of the consignment is carried out promptly. The product was delivered but late; I assume that due to the small gray packaging the consignment has slipped at the post office in any corner and came out of there again only after several days. Please when sending strings using a normal envelope in addition; then the program does not slip somewhere else ... the only reason a star deduction. Everything else was top! ; O)
