Ex Input:
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.

Ex Output:
negative

I'm 6ft and 145lbs. I order the size 4 and they fit a little big but that the look I was going for. I could have fit into a size 2 just fine. I love these jean

Ex Output:
positive

Ex Input:
Easy 5 star, exactly what I was looking for, went for the softer white because another review said they were really bright and I was going for a softer aesthetic.

Ex Output:
positive
