After about a week, I had not yet received any goods. That is, I wrote an e-mail. It was also a quick answer me the following content:
Dear customer,
Unfortunately we had to cancel your order, because we had put false information on the goods in Amazon. The purchase amount will be refunded back naturally. We ask your pardon for the complications.
That's a bad joke. And now these things cost between 3-5.
For the quality of course I can not say anything because I never had the product in hand.
