Either the product is correct but the components inside are really very low end start it makes a noise "countdown explosive" (as in the films of "tick-tick" at regular intervals) and it's really annoying I swapped my hard drive in another case (better quality) and there no problems, so it comes right from the box narrange which nothing more is that for it to work you have to connect 2 USB outputs where other boxes 1 alone is sufficient Overall I definitely would not recommend even for this price, it is better to add 2 or 3 more and have something suitable
