Good enough, but not the best. Wouldnt use for longer than 4 meters of connection to headphones, etc.

Summary: It works, not as well as some others I have tested, but it works. Installation on Windows 8 was painless and drivers installed without disk included. Small and easy to install. Not really much else to say. Would rate it higher if the range was as specified. I had trouble reaching 5 meters without losing signal quality and other units I tested easily reached 10 meters.
Summary: Nowhere in the description does it mention that it doesn't work with Windows Vista. After several hours and looking at the various comments already made, I made the realization that it would not work at all. Seems like a huuuuge oversight.
Summary: This adapter works well and I am pleased enough. I just wish that my laptop had BT built in! The "dongle" protrudes ever so slightly, but enough that it forces me to carry the laptop in my pack dongle-up. It also occupies one of my three precious USB slots. It would be nice to see a standardized internal BT location on laptops separate from USB. This, however, is a critique of the state-of-the-art, not the ASUS USB Adapter.
Summary: If you've got six hours to kill and are willing to throw out some money, this is the product for you! This Asus USB-BT400 comes with a driver installation disk that will not install on ANY computer I have tried it on. "You have the wrong operating system" "Your operating system is not up to date" "you need to consult with the manufacturer" (I could not find any way to reach ASUS.) Before you buy this product consider these factors: 1. The disk lists Windows XP, 7 and 8.
Low profile BT Adapter that performs! I DO highly recommend it after my several months of use.

Summary: I purchased this months ago, to use on my 6 year old HP laptop Elitebook and after 5 months, it has worked flawlessly, to my WiFi home system. I'm an electronics JUNKY, yep, totally addicted which lead me to purchase this BT adapter. It works at home, at Starbucks and also the grocery store WiFi. I take my laptop everywhere and use WiFi with this adapter. It is such a low profile that I never take it out of my laptop.
