The loops for attachment to the camera are unfortunately so short that they - at least for my character (neither very large nor very thick) - are not enough to lift the camera to take pictures of the eye when the camera straps are clipped. In order to raise the camera enough, I would have put the straps under the armpits extremely far - but then the camera pulls weight throughout the belt back to the front and the pad pressed from behind the neck.
As the accompanying additional set loops was just short, I had to unfortunately return.
2 points for the good idea per se, the prompt delivery, and evidently good workmanship.
