Summary: I ordered this product after the Network Adapter that came with my desktop computer was lost after moving to a new house. I spent quite some time looking for an adapter that had good quality and was at an acceptable price. This product was actually recommended to me by a customer service representative that works for the company which my computer came from (Cyber Power PC) I figured that he knew what he was talking about so I ordered this one.
Summary: The drivers for this come on a MINI CD that won't fit into a slot-type CD drive as on Macs. I had to go to the website to download the driver, but the links were all broken. Inevitably, i copied the mini-CD on a PC and burned it to a standard size CD and installed the driver on my Mac. The antenna worked for about 15 minutes, then with no other configuration changes, simply stopped working.
Summary: This product is pretty simple and easy to use, not to mention cheap. One downside is the range isn't really the best. One other thing, the plastic casing around it is pretty big, so much so that if you have another USB port next to it or under the one this is plugged into, you will not likely be able to plug in another USB device while that one is plugged in.
Summary: I don't know about the output wattage claim, but this little jewel has been there for me on more than one occasion. I keep this in my kit so I have a second WiFi adapter to try when a customer is experiencing connectivity problems. I've never used it with Backtrack or any of the other Pen-testing Linux distros or apps, but I understand this particular WiFi dongle is favored by those who do use Linux for pen-testing, at least when they can't use their on-board wifi.
