I have to add my voice to those who are saying it doesn't work. I have a nice Nanuk case and that is where my P3 4K lives when I am not using it. The Clamp/Cover falls off as I put it into the case. This is not a fitted area as I do not use the soft foam that came with the case. If I manage to get it into the case without it falling off it will somehow falls off while the case is just sitting in my office. It is never in place when I go to pull my Phantom out of the case. I am looking for something else.
