I am using this for recording instruments. The idea is to get the pick-up on a different plain than the video. The bar moves the mike far enough so that the directional instruments can be pointed at the mike without interfering with the visual formatting. It is working very well for this. It is well built and well designed. And light weight!
It's a very solidly built cold shoe extension and does what it's supposed to do. No complaints. :)
Great way for me to have three speedlites on the same stand.
