I know someone who owns the one you mention AND the other one that seems to be mentioned just as much and marketed just as hard.
He was disappointed in the first one and bought the other. Just as disappointed. He has spent a bunch of money on them and yes, they are usable especially in closer, but out in the open, say 300 yards and beyond, save your money.
We looked them both over at my spot where you can see out to 800 yards and I didn't get excited about anything they were capable of over 200. Exaggerated marketing for certain. I can use either whenever, but dont bother. Im just glad I decided against buying my own before he bought his and I got first hand exposure to them. No thanks.
