I bought of of those scopes a couple of years ago in the 5-25x model..As I liked the wide range of powers and it looked like it had some quality..Heavy and solidly built...
The reviewer made a point of not being able to hear/feel the clicks in turrets,,,It all depends on how "unlocked" you set the adjustment knobs...If they are totally released, there is no 'feeling/hearing' and you read the numbers on the dial for stealth...If you partially unlock them, then you can count by feel...Just a comment in fairness to the scope...
My initial problem with it was that the illumination portion was incorporated into the housing that holds the reticle adjustments and I couldn't find a mount for an AR that provided enough length between the rings to hold the scope...
I called the company in Springfield, MO and got a lot of lame excuses about how the military had no problem mounting them, but they couldn't advise me on a mounting system....I notice that the one in the video, now has the illumination housing near the ocular end...
Fortunately, the store where I bought it was very willing to take it back and I think it may still be in their display case...Unfortunately, since I never got to mount it, I can't comment on the actually quality of the glass, and it looked really like it had some quality...
