good product ... apparently

At first glance the product looks fine. He worked on his arrival, and its design is rather neat, including switches and blue LEDs that are very professional.
Unfortunately, there is the hidden part of the ice berg: After spending two months in the original carton with no use, I realize that it is dysfunctional, quite randomly. By removing I then noticed that there is a connection problem, or poorly made welding, at the USB output to PC (hard to know exactly. What is certain is that it was maintain hold pressed for this to work so). The rest seemed to work, but the welds did not seem to be in excellent condition (coming down?).
In short, an interesting article seemingly cheap, but perhaps a little too much if it will at the expense of reliability. I think it's worth it to put 10 more to see a more reliable brand.
