It was still possible to hear the camera, but only just. For courtroom work, and perhaps even long-lens golf photography, the Camera Muzzle should mute camera noise more than enough to keep the attention focused on the event and not you. In fact, in certain jurisdictions, it may be the only way to gain permission to shoot courtroom photos. Though Cranston initially did the assembly and stitching, a local tailor now handles that task. They vary in height, and in the position of the viewfinder opening.
Customized versions are available as well.
A revised Camera Muzzle, with a single zipper in place of the bottom and side flap velcro closures used in the current model, will begin shipping in September. Faster shipping, or shipping outside of the US, is extra. Cranston is currently on assignment overseas and may be slow to answer email requests for information until later this month. It really does work. It's way quieter than the old Nikon CS-13 soft blimp, and your hand doesn't turn into a prune inside it.
