I own one myself. its my backup I let all my friends use it and ive used it a few times to lend out my etek3.
and your getting reliability, ease of maintenace, overall GREAT marker for a good price.
dont listen to all this detail junk about vibration, noise, blah blah.
Sorry the nit-picking over spilled milk annoys me. if you have girly twig arms and horrible muscle memory...then i think this gun or ANY gun would be bad for you.
All you should worry about is performance, reliability, maintenace, and any issues...
which this gun has none of. so enjoy
