Does anyone have any experience with this product.
It looks like a good idea,and could shave off 30 grams from losing the battery. :ugeek:

It would be very cool to have a proper backpack for the GoPro that would allow you to control the camera like you would a gimbal control. Being able to switch between photo and video and the like would be handy. This device is at least part of the way there.
