Things I liked:Decent quality materials. Very accurate when cleaned. Nice trigger. Things I would have changed:Quality control is pretty bad. Loose parts, dirty barrel. Is pretty hard to cock it since the rear sights are sharp. What others should know:MUST be disassembled and cleaned / lubed before using. My main valve started leaking after only 40 shots. I had lubed into piston with Pellgunoil but must not have got enuff in there. Seal was nibbled and ruined. Follow a guide on the internet, several good ones out there. After rebuilding valve and lubing, have shot 200 rounds since and it doesn't leak at all. It's now a very nice airgun.
