No, I wouldn't buy that, and I didn't.
Just thought i'd offer an alternative to BR, have you seen the Bos Strap? Mine is awesome and I feel more secure with the camera attached to a single neck strap loop than the tripod mount.
Checking out the link, I noticed the following statement under "product description" (re the Bos Strap) : "Helps reduce the stress and possible damage to your camera body tripod socket and internal seals when hanging the camera upside down from a tripod socket fitting." As I have a Black Rapid, which as everyone knows attaches via the tripod socket, I find this slightly alarming - does hanging a camera from a tripod socket fitting REALLY put undue stress on the tripod socket and internal seals to the point of damaging them, or is this just marketing hype?
If you read the reviews on BH, amazon, adorama, all of them have a few percent of people at least that claim their camera somehow fell and smashed to the ground. Made me a little nervous. I like the Bos Strap because there are no clips at all, and no screws to come undone. I have used both a 5DC and D700 on it and although I was nervous at first(mostly of the Nikon shoulder strap loop breaking) now I don't think twice. That screw on the BR strap seems a little shady to me, i feel like eventually it would just come unscrewed.
