I just got a WeyeFeye today and tested it out quickly and made a little review of it. It's going to allow me to have a monitor on the camera rig and a second wireless monitor for the Director 
I was debating between this and the CamRanger, but took a chance on this one because it was cheaper and looks better IMO. Since there are very few reviews I could find on it, I decided to show some of it's capabilities.
