I've got three of them. Two currently in active service. They work very well. You will need to take the time to tweak the two pots on the board to get the best quality imagery for the superimposed data. Be sure to get the most recent firmware (going from memory it's 3.2) otherwise attempting to display the BL-Ctrl temps will hang the board -- not permanently -- you just have to remove the BL-Ctrls from whichever of the four screens you had it on an re-update the board and all's well. The mini-USB connector on the SOSD board also allows you to hook up MK Tool as well.
I use it with two mini-box FPV cameras, one looking forward and slightly down, the other looking straight down -- I use a
two way video switch from dpcav.com and a Tx switch to toggle the view.
