I just ordered the BR clone - (F1) on Amazon Prime for Friday delivery. I'll use it this weekend and report back .
I already have another clone, but found it too short in the strap which locates the camera under my arm somewhat. And the attachment method was also with the tripod hole, but the screw knob is cheapo plastic, cheap looking enough to the point where I said nope, not gonna trust that. The steel was of good quality with a powder coat type finish and a lined hole for the swivel snap which was seemingly good quality as well. So the short strap length and cheap plastic retaining knob are the downfalls. One other thing that bugged me too was the strap material, not woven nylon but a probable woven poly product that is very rough and cheap looking/feeling. I guess if I had access to an industrial sewing machine, some nice flat woven tubular nylon strapping material and quality hardware, I'd make my own.
