I do offer the money back guarantee through ebay so you are protected but if there is a return you are required to pay the shipping cost back to me. If you have any questions I will be glad to answer them but I'm new at these types of items so I will be as much help as I can be. I take my feedback very serious so if you have any problems or questions please message me before complaining or leaving bad feedback.
