Some words about my first impression. I did a lot of research and read many reviews before deciding on this device. I was surprised by the clarity and the accuracy of this optics. Activating the infrared light does improve the visibility and clarity for a small area out to about 80 yards. I can't complain about the width of view or lack of auto focus because of the price.
My only complaint is that the depth of field is quite shallow (the picture has some "fish eye" distortion around the edges). Anyway you will not find better product in this price range. It works great for my purpose. Anyone that is expecting a Gen 2 or higher should spend the extra money.
