This guy bought the wrong item, and afterwards he blamed the seller for his own mistake, while he issued unreasonable demands by requiring the seller include service instructions for professional mechanics into the product listing! We explained him that we're just selling items, and not service instructions, advice or any kind of technical information as this is normally addressed to professional mechanics. Lots of emails exchanged, and replies to PayPal case. Initially, he agreed to return the item, but afterwards he had changed his mind and requested keep the item, and get refunded.

This guy is a total waste of time. Sellers, you'd better avoid any business with him, and cancel any order you may have already received from him.
