Works as it should. I'm new to pneumatic nailers so I wish the instructions were more detailed. The low weight is extremely practical. I haven't had any jams yet, but I did purchase Metabo 15 gauge nails as directed. I'm not sure if people who complain about getting stuck use Metabo brand nails. Ergonomics and usability are good. I bought some Metabo air oil, put a few drops in the air tube (hose connection) and I'm good to go. Always lubricate with oil before use, more frequently for prolonged use. In general it works fine.
