A part of the review has been auto-translated.
the product wasn't delivered because of problems concerning the shipment address. A complete checking confirmed that the address was correct, therefore something had happened during the shipment (address partially erased?). Anyway, I was immediately and completely refunded. Thank to the call center operators for their ready availability!
The goods arrived intact, unfortunately, so far there is no way to check the efficiency.
Arrived earlier than expected! Very good!
The camera is not working, no CD with software, the computer can't see the camera and I can't start it, after downloading the random application onto the smartphone (no original) the camera is running, but the image is blurred, no possibility to regulate caution. The camera is useless in general, I only lost money. I do not recommend this product :(
