I like to think of myself as a fair person. If this doesn’t work~ because I paid for the shipping to the buyer… if it doesn’t work… spend the couple dollars it will cost and send it back to me, and I will refund the buyers credits for this item~ Only when I receive the item back will I refund the credits. I think that’s fair. (But I am pretty sure this will work just fine) If I get the item back empty, I will know the buyer used it and returned it empty. That will not count. Lol
