Good but takes time to configure to work correctly
28 March 2015
Summary: I really like this adapter it has really good range but when you configure it at first it really takes a lot of playing around with to get it working properly. I use it for both windows 7, windows server 2012, and kali along with backtrack 5 r3.
Very good at picking up distant signals; easy to make directional with a reflector.

Summary: I was a bit skeptical about this, but it came highly recommended on many war driving tutorials. I needed something I could directionalize with a reflector and this did the trick; (Simple half-cylinder of cardboard/aluminum foil) At work I was able to locate a rogue access point from a quarter mile...
Summary: This worked OK for a couple of years, then started acting really odd. I had to keep un-plugging it and re-plugging it back in for it to work (multiple different computers, all had the same problem).
Not even good as a door stop, but when it works, it works good, but not for long.

Summary: I ordered it and used it a few times. It stopped working and went through the bothersome and lengthy process to get it fixed. When I got it back, it worked the first time I used it. After that, it never worked again.
Summary: theirs no tracking on this package ...all dealers are in japan....arrived about 32 days after order... product is stronger and better than the linksys usb wifi adapter i bought 3 years ago for $60 their now selling it for $40...
Summary: Under Windows, you need to install the driver from the Alpha website. On doing that, I get 15 Mbps on speedtest, which is great given that my router is >100ft away. In Linux, the driver is simply the one put out by Realtk, which is terrible.
