Negative star for quality checks - AIM Sports Inc 30mm QD Cantilever Scope Mount

I bought this earlier in the year with the hope of finding a decent low cost QD mount. When I finally pull it out of the box months later, I see that it's missing 1 of the 8 ring screws. I really wanted to like this product but it's hard trust the quality when when the manufacturer can't be bothered to do basic quality checks.
