They sound a little bit mechanical for the setting. Couldnt we get a more swishing sound? Or maybe something like changing your grasp on something hollow and plastic?
Maybe something from freesound.org could do the trick? Like a click or swish? I think most of them would sound preferable to the computer chirp. Something like the weapon_clipin_rapid.wave here: http://www.freesound.org/tagsViewSingle.php?id=18621 ... would sound nice I think.
