[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]: I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.
[A]: positive


[Q]: This is a big piece of junk! The band is enormous, large enough for a 400 pound man’s arm. The biggest annoyance of this band with that once it on it’s impossible to get off without breaking the band! Do not buy this. I have attached a picture to this review what about looks like after trying to remove it. Not to mention I scraped up this relatively new Samsung gear S2. Going to try to attempt a return.
[A]:
negative
