The look, amazing, the crosshair, amazing, and the fact that it came be illuminated is great. It can easily be zeroed to where you'd like as well.
Construction is awesome. It looks sweet.
Good crosshair, easily zeroed in, and it's illuminated
The only con:
Eye relief isn't great, you have to get pretty close to look down it, and the 4x zoom can be a little too much for airsoft sometimes.
