Ive been selling on eBay 20 plus years their policies have changed so many times. I agree you can choose a no return policy but if someone complains item not as described ect eBay 99 percent of the time sides with the buyer when a case is open. All they need to show is that they mailed it back to you many times its not the original item or nothings in the package . Most sellers, there is even a huge forum on this issue. just refund to avoid a neg feedback and then put them on a BBL list!!! I have found most buyers and sellers don't have to deal with these kind of situations. I would never sell Electronics I know many Top rated sellers who deal with this kind of thing on a regular basis. Im Top rated but I don't sell high value items ie over 150.00 to avoid these trollers usually buyers with low or no fb which we can filter with buyer requirements but just a little ,or buyers from other Countries. I hope you figure out what your going to do if this seller has good feedback will tell you a lot. Good luck my friend!!Tommy
