I have had it for a while, and the rifle has seen about 150 rounds. Last weekend, I took it out for some fun shooting, and the crosshairs are off.
Basically, the crosshairs are out of focus. You can focus on them, and the target is blurry, or you can focus on the target, and the crosshair is almost invisible. Switching focus from one to the other, the rifle still shoots good groups, although not as good as when the scope is working right...
So, time to test their warranty!
