PROBLEM: Since I badly need the 4:3 ratio for FPV flying, I will keep this unit. However, the USB power supply failed after second time I inserted it. Total junk design. However, opening up the unit, the connections for the supply are pretty obvious, and I think I can fix it. If you are not good at soldering iron, stay away from this equipment like hell, there is no way it would last longer than a couple of days, and there is a clear manufacturing failure. As far as quality (video) is concerned, it seemed to be OK, I have not noticed any major problems during the half-hour I was able to test out the unit. Quality is good, 4:3, 16:9 switchable, as advertized.

SOLUTION: negative
