I bought this item believing it to be a good make, probably mistaken by the company name of ComproUSA.
This item failed to work, contact with the compro help line (which for info is in Taiwan) was useless, their lack of comprehensible english made it not only difficult to understand them but for them to understand my problem, they merely kept repeating themselves.
I would point out that I am not a basic pc user but in fact a hardware engineer with 16 years experience working for companies such as Compaq, fujitsu Siemens, Toshiba to name just a few and basically I just could not get this item to work.
I subsequently replaced it with what is a cheaper make (Kworld) which installed with no problem.
Just do not give yourself the headache of trying to get this working, I spent 3 days trying to make this item work.
