He expressed very clearly in the auction that there are to be no returns, i've even approached him about a return but he just disappeared, hence nothing to lose other than wasted time and a little money.
Ebay auction? If so, even if he said no returns the item has to be in "as described" condition. If it was sold as used but fully functional you have the right to send it back. Should he refuse you can open a case against him which, given the evidence will end up in your favour.
