Q: 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.

A: negative

Q: OMG! I have found a new author for adults! Alexandria House is a magnificent author who uses vivid imagery, vast descriptive vocabulary to increase the reader’s knowledge while keeping your attention! I purchased her book from Amazon at 8:30 and I am on chapter 13 in less than 3 hours and was at chapter 23 by 2:30 a.m. I was even not sleepy for work because I felt sooooooo relaxed and couldn’t wait to get back to reading. Book is finished and I am purchasing book 2 tonight!
