Broken product? - SIG SAUER Juliet6 6x24mm Red Dot Sight Magnifier

Put this on my AR15. My unit may have been defective, the diopter didn't function at all to adjust red dot clarity or eye relief, and the viewing angle was literally a mere few degrees, otherwise you see only black. The mount was also out of spec to the rail as you had to force the lever closed to click into a locked position, and it was probably canted left or right a little it to keep it off axis from the two red dots I tried. A Romeo 5 turned into an oval blur, and a MD-25 was crisp but only when viewed at one particular weird angle, otherwise it was a haze.

The other reviewers got a great unit but mine had me scratching me head, wondering how this got past QC. Not a happy camper and am returning this for a scope instead.
