I received my Spark Core 2 days ago. I know a lot about night vision but I still couldn't believe it can be possible that a gen 1 monocular has a gen 2 image quality. It is not that expensive so I wanted to try it myself. No kidding... It is really great!! Very close to gen 2 monoculars in picture clarity and brightness. That really is something new in technology. If they move on like that we'll probably have gen 2 nv at 100$ by 2015.
As earlier reviews discussed, except clarity and comfort. Also purchased the headband and with that, it moves from left or right eye, up and out of the way when not needed, buttons are noiseless. Exceptional vision quality
