Everyone who shoots my Neos enjoys it, and that is pretty much the goal with .22 semi-autos. The extractor claw is necessarily pretty small and fouling produces failures to extract if you don't clean it properly. Other than that the little bugger has been completely reliable.
Lots of people gripe about the reliability of .22LR bulk ammo, but I have had precious few failures. If a round doesn't fire, eject it and go on. It's .22LR, and you chose your pistol because the ammo was cheap as dirt.
