I was hesitant, however I must say I just got mine in the mail a few minutes ago. It works AWESOME just like the videos show. I only have one regret, I only ordered one for the S&W R8 and now I need to order one for my S&W 625. Money WELL spent, and quick professional service.
It really does work this easy...

Cool thing also as compared to the original design, they have installed little magnets to keep the moon clip in place.

Carry safe and carry when and where you can. I'm just sayin'.
