not very good at all, just a waste of filament, supports where there didn’t need any, the cocking mechanism has a hard time pulling back and doesn’t have any rubber band to pull it back into place, needs glue everywhere, everything doesn’t fit together especially because of the glue, could’ve been designed a lot better.
do you throw away the black rectangles that fit it together? it aligned everything and helps hold it together nicely. mine is fitting together nicely and I haven’t glued it yet.
