As the author of the blog post (and Blair's better half

), allow me clarify what happened.
Sitting in a chair, I attached the strap to the camera. Clipped in and locked the caribeener by twisting it until it covered the piece of the clasp that flips open on the caribeener. The lock I am talking about keeps it from flipping open, or is supposed to anyway. It was tight. I checked twice because I'm paranoid ocd about these kinds of things.
Stood up, walked outside, and about 10 minutes later after having it sitting at my side (i took maybe two photos), the twisty locking mechanism that keeps the clip from opening unscrewed itself. My cellphone rang and I reached for it, at which point the caribeener clip opened and the camera fell off the clip. The "fastenr" attachment was still securely connected to the camera. I sat astonished wondering how it happened - like just having seen the magic trick with two "solid" metal rings somehow detach from each other. After inspection, the clip had opened because the screw-closed locking mechanism failed (unscrewed) leaving the clip vulnerable and thus the camera insecure.
So the failure is not with the metal or the entire clip or the fastenr, it was with the locking mechanism on the clip. It unscrews too easily. It was just general activity that loosened it. It does not lock tight enough when screwed up over the clip opening point. Once failed and unscrewed (which happens too easily), the clip is vulnerable to opening unexpectedly. One wrong movement, and the camera (fastenr happily attached) can fall to the ground :x. head first

.
And of course I was at a workshop, so after the occurrence,
multiple female photographers came up to me and told me that they had similar problems with their RS-W1s (but not with their men's version, which I have also used extensively and never had a problem with). The female strap was a recent purchase because, well, in a word - boobs.
So yes, this could have been fixed easily with a piece of gaff tape or duct tape, but after trusting in the brand through previous experience with RS-4s, I never thought it was possible or probable. I will ALWAYS use tape in the future even with my RS-4, but clearly there is a design flaw if the clip's screw-lock can come undone so quickly and so easily.
And there's the rub with trust placed in a brand like Blackrapid...you are left vulnerable when their designs or production come up short compared to the rest of their products.
