    Pros: It's small, cheap, and robust. It doesn't feel flimsy when I try to plug it in and it does its job. Pretty much plug and play. It does come with a driver disc, but Windows update did the job for me. Cons: Non that I can recognize. Well, it flashes uncontrollable, but that doesn't really me... Read more

    When I install the software from the bundled DVD it installs and then I'm told that 'I don't have a valid license to run CSR Harmony Wireless Software'. And I can't make it work

    Pro: Installed really fast and worked right off the bat. I was pleasantly surprised at how well it worked and the range that I got off of it. It paired with my Bluetooth headset instantly. Cons: None, really. Other thoughts: Package arrived early which was very good, too.
