There is a review of it in the review section.
I have one and love it.
Glass is ATROCIOUS compared to a Vortex PST even.
That being said, if you can read wind it is probably the deadliest system on the planet for game. The speed of the system is the key. Push button and fire VS Range. calc shot, fire.
If something is bedded I would choose something else. Average game shot I run the Elim.
