Hi guys, need your help, I just received my KGo Vv by Hoosier.com, variable voltage is nice, built is nice rubbery like the ego, but I have a problem. My problem is the fire button sticking after I fire it it sticks on more for 2 seconds. I am not using the rubber cover over the button, the button is also sensitive and it automatically fires, it's from Hoosier.com, thanks guys thankyou for your time to read this,
