What can I say? This thing works perfectly and has done so for the past year with no disconnections. I can't say the same for cheaper USB wifi adapters that I've used. This thing just works. The only con I can think of is that it's a bit bulky.
I've been using this for a while now. It's working perfectly with my old D-Link Wireless G router so I'm happy. Installation was very simple. The only con is it's a little big. It's a little larger than the size of a USB stick.
