 If you do purchase an ebay item from me and for some reason are not satisfied or have questions, PLEASE contact me right away and I will take care of it to your satisfaction, (rather than leaving negative or neutral feedback before I am made aware of a problem).

 I sell hundreds of pieces of used and new gear and it is possible I could miss something or make an occasional mistake, but I will always work to make sure you will be satisfied or I will refund your full payment including the shipping cost, so there is no risk you will be stuck with something that you do not want. 

I know there are many sellers that do not much care about your satisfaction but I am not one of them! Please consider this before you bid on my items and before leaving any negative or neutral feedback.
