- The camera itself was defective because an object moving indoors. The objective perhaps?
- The whole object (with accessories) was sold without packaging bare, and with instructions in English only
- The case seemed already bad since I broke the closure (not elsewhere closed)
In short I make this article as it appeared in his bubble paper and I advise to opt for the same item (another brand but it's EXACTLY the same object) and 15 cheaper than you will find here on Amazon.
Note that I do not want to Amazon which is only just a dealer and he has my full confidence to repay me.
