He declared the wrong shipping address when he placed the order, and afterwards he opened a case in PayPal claiming that he had never received the item. We had to involve PayPal customer service so as to get our funds back.

WARNING: Sellers be aware of this buyer! This is a real scammer who can waste your valuable time with PayPal cases and emails even for an order of a couple of Euros. If you receive an order from him, you'd better cancel it; otherwise prepare yourselves for a real trouble.
