A star in hell

We ordered this camera according to the different opinions of the site and by searching on the internet from the reference SJ4000 full HD 1080P. Then falls then on SJCAM SJ4000 whose opinions are quite positive. So we order.
We knew that the delivery will take time (always reviews on Amazon). And it's true: delivery after 25 days. I had emailed the seller to find out where it was and I was told (in French knowing that it comes from Hong Kong) that I had to wait.
So, the camera comes ...
First surprise: no marks nor on the box (which looks like two drops of water to SJCAM SJ4000) or on the camera. The manual includes many languages ​​except French. I looked for an internet address in this manual for the instructions (perhaps) in French and updates to Frimware, software for the camera. Niet, nada, nothing, nichts ... no websites. Nothing that can not connect me my camera (which is a gift for my 11 year old son) to a company (but does exist).
Second surprise: bolts that are not working. Naively, I send an email to SJCAM that meets me after several days: "IT'S A FAKE" (sic) (for non-English speakers: THIS IS AN INFRINGEMENT). My suspicions' already heavy) were therefore justified.
I send an email through the first response from the seller (if you follow, the one where he said in French to be patient for delivery). No answer.
My wife, being vindictive face the despair of our son, called Amazon.
In this adventure, Amazon assured. They sent an email to the seller with a copy to your servant.
Vendor response the next day with an apology in French (it still does not walk the camera but it's always nice anyway) and repayment proposal. We accept. Reimbursement made 48 hours after all the procedures by Amazon.
Finally, Amazon has overtaken the problems and has managed them. However, if the site sells well the goods described this camera truly is a counterfeit of the SJCAM SJ4000 and is nothing else. Perhaps is it still a good product (difficult to assess when you can not not do zoom out and start recording) and I am left to redeem my son doing VERY careful. .. brand.
