Hello everyone, I confirm the comment of Alain Brachet on "the scam of the day" March 17, 2010 This material does not recognize anything and for the price I will not take my head to return it, it would cost me too much. I received an unknown brand equipment, in a simple plastic bag without Reference, without notice or cd, a real lack of respect for the customer because we do not know how to refer manufacturing site to find product information (driver , advice, inconsistency, update ...). I wish I had the feeling of buying a product effective and serious in finding the blister with a brand, a manual and a CD, but the reception I knew immediately that I was not going to be satisfied. We feel that this article is sold off without real results guarantee.
