PNC / Kamerar / Socom PR-1 Prime Video Rig

Hi everyone,
I came across the PNC PR-1 Prime Video Rig (http://www.photographyandcinema.com/pro ... eo-rig-kit) and I was wondering whether anybody has used one of these? I was considering buying it as an entry level shoulder rig for the BMCC. I don't want to kit it out massively, just attach the camera and shoot. Since it has an off-set bracket, the BMCC display would be closer to my face, but I am wondering how stable these brackets are considering they would "carry" the whole weight of the camera.
Let me know what you think.
