Full/Partial Refund Scammer. Possibly middle-aged and not technically savvy. Once buyer receives item, they will start to play partial refund / feedback extortion games. Once they have your item, they will complain about ANY THING they can think of. Things that have the most obvious common and easy solutions. Could be even considered general maintenance of an item. Doesn't matter. They'll say whatever they can to get a better deal or happily send it back on your dime. They abuse eBay's ToS. Avoid at all costs.
