Things I liked: nicely finished metal and wood, better than I expected from a Chinese gun
Things I would have changed: the rear sight is a bit crude but useful...I disassembled and lapped in the working surfaces to improve the movement of the aperture in vertical and horizontal
What others should know: My .22 chronys at around 500fps with 14 gr pellets of various types. I just installed some Archer parts to increase the FPS. The loading of the CO2 is a pain so I converted to a bulk fill adapter from Archer too.
