He has 5819 transactions with only a handful of bad feedback. If you read it, you'll see that many of them are from people who apparently didn't read the description or just like to whine. Like the ones where he has offered a return and money back, but the buyers refused and gave him bad feedback instead. People like that are obviously happy enough with what they received, but they still want to complain. One guy didn't even get the gun as there was a part missing, the seller returned the money plus a few $ extra for the hassle, but the buyer still left a D. When I read through all the feedback I get the impression that there's nothing wrong with the seller, I'd rather say there's something wrong with some of the buyers. Every business owner will encounter this type of customer, it's just part of it.The seller does have a number of negative feedbacks. Too many for me.
