[EX Q]: Bought for preteen daughter. Easy to use. We put curl cream in hair while wet, then put these in her hair and kept them in over night. Curls looked great. No tangles when removing. Great quality for price. Delivered quick.
[EX A]: positive

[EX 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.
[EX A]: negative

[EX Q]: Just what I needed to add some more organization to my office. Now I have lots for flat space for showing off my Lego collections at work! Given the way the pieces lock together you cannot move it after you have put anything in it as it might cause a fitting to work lose and it can be difficult to get it put back together.
[EX A]:
positive
