thank you for your response I did watch several videos although the links you provided I never seen and were helpful as I think they were the only English ones I've seen. My concern with videos is they can be edited, and while I am not suggesting these are, I value the experiences of actual owner/users to help decide. I know some people just always seem to get a bad one and some hit the lottery every time but I like to research as much as possible and like with these guns I feel safe jumping in.But now concerns pop up so I just wanted to open a place up for others like me to do research as only reviews I seem to find are written by sellers or written in Turkish
