This instruction guide is not a model of clarity, I wondered if I had misunderstood an instruction, so I tested all possible alternatives.
Reading the visible evidence on this Amazon page, I found that another person (SmileSurf) was like me who have failed, while a third columnist (GADLU) had obviously managed to get his camera. I questioned GADLU, who confirmed having operated like me in my first attempts. So until proven otherwise Smilesurf and I are not sub-talented.
More recently, as of May 13, 2015, I note that 5 of 12 comments show a product that just does not. The default rate is 42%, which is incredibly high!
This camera may be well designed, but it is made without any rigor or with very poor components, and obviously there is no quality control at the end of assembly.
Do not buy this product because it is a real lottery. Know that Ultrasport is not a manufacturer but a Reseller branded with his name. I already tested an embedded mini camera UltraPort that it worked perfectly; no doubt it came from another supplier. A Ultrasport to better select its industrial partners, demanding from them a real quality control.
