Good and sturdy build
The tiny spring on the battery cover falls off when I first open it, and lost it. So I have no chance to try the vibration feature.
Gun is heavy after adding on the wiimote, which fits nicely and perfectly.
Build material for the gun is of good quality and doesn't gives you the cheap plasticky feel

Good enough
Require 2 AA batteries for the vibration.The gun itself it's quite heavy but made from nice material.But,the vibration is very soft only
