5 out of 5 eggsTa-da!

Pros: Works as advertised
Easy install

Cons: None

Other Thoughts: I was looking for a card that didn't add multple USBs to the back of the case. This does the trick and zero install issues with Win-7/64 unlike other cards. Once and done!

5 out of 5 eggsseems to work well

Pros: It works well, I've tried a usb.3 drive on it and the speed is as fast as on my other system. It looks nice. It installed easily except for the driver (see below). All in all, I'm pleased. I've always been happy with Silverstone products, and this one has not disappointed.

Cons: None really except that you really need to push in your usb device. It is as though the USB socket is too tight. That's good, but at first I was not getting connections.

Other Thoughts: 1. The drivers from the web site did not work. The one driver listed as EC03-P did work. It's on the tiny little CD they send. It was actually a newer driver then either on the web site. That was unusual.

2. I had to re-boot before my USB drive worked and was recognized by the system.
