Great optic and solid headgear. I have a single black dot in my tube, but only visible with IR. Works well, but if batteries are low it will start acting odd (failing to turn on periodically). I wish there was a dedicated IR button and the IR light itself could have a wider range. Met expectations and I'm overall very happy.
Pros: Light, Rugged, Clear, Solid Head Mount
Cons: Would prefer dedicated IR button
