Generally a very good product, slight overheating issues (it does tend to run hot if used continously), however I have used this device pretty much 24x7 for a month and it didnt melt!

The device is prism2 based and is compatible with linux via the linux-wlan-ng driver. However you will require a newer version >= linux-wlan-ng-0.2.1-pre19, earlier versions do not seem to work with this device.

Setting up driver is easy however requires a degree of linux knowledge, personally found that the driver crashes from time to time during a dhcpcd request though very infrequenctly.

Signal is reasonable and reliable, though not superb.

See http://www.linuxquestions.org/questions/showthread.php?s=&threadid=184459 for a quick how-to with the linux-wlan-ng driver

Be aware of the version 2 of this product. If you get one of these won't you be able to get a working internet. :(
