I recently acquired the QC clone in a trade that my first shave like that but the second shave I noticed that the blade balance was off the one side is normal but the other side is too aggressive and I even got next on one of the lower settings !!!
The cap can go on two ways - correct or other. There's two tiny marks (A) on one end of the top of the base plate. The cap has a shape that comfortably fits your thumb (B) when taking it off. Those two go at opposite ends for the blade to align properly. Mine is a Ming Shi 2000s. As far as I know it's the same razor from the same production line, in a different box.
