Great idea but massive failure! - Strike Industries AR Multi-Angled Pistol Grip

First off, I LOVE Strike Industries innovative and great looking products. They are probably some of the coolest AR parts on the planet. I had high hopes of adjusting the grip to my own preferenced angle. And sure it adjusts...but then it does not lock the grip adjustment solid in place. You can literally rock this grip back and forth and it will wobble back and forth like a 1/2" or more. I mean this is a massive engineering failure! How could they have not tried this in the factory and seen that you do not have a solidly locked grip in place?? Anyway, this went back to OP. SI needs the engineers to give this a total redo!
