This is the second one of these guys I picked up. The other was by an even more generic brand than Belkin.
Uses the Realtek chipset, so the parts are made by a good name in ICs.
I purchase a ton of these usb wireless sticks to grab updates on machines when there are no lan-patches available, so you can trust me when i say it works fine for the price. People who are having problems with these adapters are really having problems with their networks.
Also, these only work on 32 bit versions of windows as far as I know. Although, I would not be surprised if you could find a Realtek driver that fixes that issue.
CHEERS.
