Experience: 1 Years
It was inexpensive at the time of purchase.
Signal strength is low
Link speed is low
I have had mine for over a year and it works.
Set in wireless N mode my average signal strength is 29-34% at 25' 1 floor and 1 wall away from router.
The average link speed using wireless N is 39mbps.
When playing games online the connection will drop  frequently.

Experience: 2 Months

three antenna look cool
cumbersome installation, weak signal.
I have Fortress FB02 and if you place the metal guard above the antenna, the signal disconnects completely.
As well, you have to install the included driver on cd BEFORE you plug the card.

Experience: 4 Months

Good range
Fast connection
doesn't work with extreme amounts of interference (as with any other wireless antenna)
Overall, the signal is quite strong (router to antenna distance is approximately 20m, same floor, through several walls). On average I get signals of approximately 80%.

I haven't been able to use the wifi on the desktop however due to the extreme amount of interference that goes on under the desk (limited space, powerbars and wires running everywhere).

However, definitely a good buy if you have a clean floor/working area!

Doing what its supposed to !
INstalled it on my PC. INstall new driver and voila !
really good N-G-B adapter. Cant go wrong with this card.

Experience: 2 Days
 Verified Owner
-Was an amazing 45% off in recent sale
-Very fast.
-No software tools but that could actually be a strength because some software tools can be very unnecessary.
Well, it's cheap and it's fast. The only thing I haven't tested is local network transfer via wi-fi, but my internet connection is extremely fast so far - rivalling the wired connection I ran at my old home. Definitely recommend!

Works fairly well
Signal isn't as strong as I had expected
My old one broke down and I ended up grabbing this one because of the three antennas. Surprisingly, it gives me the same signal as I had with my old card with just one antenna, not that that's a bad thing since I get a decent signal through 2 floors. I do notice it cutting out for a second every 10-30 seconds when I play games though, but I can live with that.

Works very well, good price , wifi N
signal is little weak but without interruptions , outdated drivers
I got it to replace ASUS wifi adapter which was horrible , this one its much better , unfortunately there are G devices on my network so I cant test N speed but overall very good product.

One more thing the device got recognized in Windows 7 as Ralink and CD drivers are too old go to and download drivers from there
