Summary: I wasn't sure about the product because some people left negative feedback. I was pleasantly surprised to find it quite good. Well built and works great off the box. I installed just driver only, not the software that came with it. My desktop is only about 7-8 ft away from the router and it's getting full signal strength.
Summary: I have adopted TP-Link products. I took a chance on a 300Mbps router and have been buying their products ever since.
Pros: I got a great deal on this for $9.99. I needed a wireless adapter for my media pc and this dongle works great. It is still streaming without a problem. The network software included is also nice, allowing you to view all of the wireless networks in the area and allows you to choose which channel to connect to based off of signal quality.
Cons: Driver does not install automatically. Must use disk.
