Well, when I plug in a battery on a brand new gun, only to have it lock up without firing one bb, try to find the problem unsuccessfully, RMA it, only to have it still not work properly, and in the end never have it work properly, that says something. :/ Granted, Tiki is not an outstanding tech, but the Tactac tech is decent as far as I can tell, and even after it got downgraded to a non-retarded FPS level, it worked poorly.
Say what you will, but that scared me away from VFC gearboxes.
