WOW...A must for any Chess player. Quality in every way. Buy it for yourself, buy it for a chess player in your family. A chess tournament in a portable case. Look, at the others, read the reviews, then buy the real deal...!!!

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.

**NOT COLOR SAFE!** My hair was purple before I used this. I diluted this a great deal- I saw the review that said use less for fine hair and I have RIDICULOUSLY fine hair. I'm pretty sure I did a couple teaspoons in 1/2 cup of water. All blue tones are GONE from my hair.
