I've gone through 2 batteries (I'm certain the second was turned off), have yet to even mount it on a rifle. Im about 4 weeks on the current battery, It did stop working and I had to take the battery out re install it, its been work since. When you look in it there is a dark splotchy area were the dot is you can also see a straight line in the optic that leads to the splotch (I see the line even on the one photo on the web site). Are these warranty issues, never having one of these before not sure what the expectation is? I'm under whelmed. What the hell is that screw that is on the side of mine, I notice its not on the one on the website and it looks pretty unprofessional. There was a piece of thread on this screw, looked like from a hang tag. Is mine some demo model or do they all have this?
