Ok , the reviews are good for that one , but as with all products there are the bad reviews also. So iy becomes a chance that you have to take and that's why I would rather take that chance with a better brand than Roswill. Rosewill has thier name on so many products that there isn't one that you can say they specialize in. So for wireless I would go with brands that are known for it. Linksys , D-link , Cisco and Netgear to name a few.
It may be just my choice but I'm not buying anything Roswill and what you decide to buy is your choice since it's your money and I'm sure that cost plays a big part in your decision making so that's what draws you to the Rosewill.
