Copies from china use the cheapest materials, steal the design, and have slave labour manufacturing. I bet a pile of parts come out of spec.......if they have specs.
That's funny you should say that.. everything is made in China. Even the highest of highest end items.
My standards aren't restricted to brand names. I go for experience based on usage. The guys over at VFRD have been using the same cheap knock offs that I bought for years with no problems. I love em and so do all the guys that have had no issues with them
Thanks for your concern though, appreciate it.
