I complained and returned the vibrator. In response, I received an email from Fun-Toys-NET that it should even report me by phone. This request, however, I have not accepted, because a 0190 service number for 1.99 euros / minute I find outrageous! Alternatively, however, they offered me to cancel the order, which I then did.
These two circumstances, namely that the batteries can not be inserted and the 0190 service number let me just awarded a total of a single star, and that's only because I have to click a star at least.
