Summary: The product lasted me quite a while. It works well with linux, and it is worth its price. If you are looking for something more high speed and have extra money, I would go with an Alfa AWUS036H.
Summary: These adapters are version 4.1. They have the Ralink RT2070 chipset. They DO NOT have the Ralink RT73 chipset. By using the rt2800usb driver, you can still inject and monitor on some versions of Linux though. Works with BT5R1 GNOME 32 & BT5R1 GNOME 64 out the box.
Summary: I got this for occasional wireless through the softAP. I loaded it up and the softAP didn't work. Went to the website and downloaded the new drivers. As the new ones installed, it apparently adjusted the computers boot sector, requiring a reformat of the hard drive. Either a virus came in from the website or the driver's installation routine is really crazy.
Summary: I bought this item about 1.5 months back. I am using it in Windows XP. However this is a useless device as the connection gets lost every few seconds. The problem is not with the network because my laptop gets excellent signal all the time without interruption. SO I suggest not to buy this crap!
Summary: I bought this for one of our legacy desktops that I occasionally update Windows or surf the net. Went to the Big Box retail, and left gagging at the cost. Went to old tried and true Amazon, and found this little gem for around $10. Easy install, even gave me the choice of installing the driver or driver AND utility. I choose driver, since the windows network interface is easy to navigate. My only regret is you can get the N version of this adapter for a couple $$ more.
Summary: I bought it for my new Windows 7 desktop and have had no problems. It installed easy and it works all right. Bot sure about its distance limitation though as my router is just 10 feet and 1 wall away.
