I'm led to believe the previous '5 star' reviews are from LogiLink themselves. They have reviewed no other items on this site.
I bought this with intentions of replacing a faulty Creative Labs X-Fi Sound Blaster external USB card, but have had NO success in even getting headphone audio output from the device.
Windows Vista does not recognize the device, despite the suggestion that it DOES on the packaging.
Seriously.. just don't bother with this. The price is enticing, but you're better of buying something that actually works. I feel like I've been completely ripped off.
