Pros: Inexpensive and it works. If the front USB ports on your case are 3.0 but your mobo only has USB 2.0 headers, this is the item to buy. As other have pointed out, obviously speed will be 2.0, but at least the ports will function.
Cons: None so far.
Overall Review: This item is shipped direct from China via International Mail. In my case, this worked out amazingly well, considering it's the USPS. Shipped China 9/20 at 7:14 pm. Delivered 9/28 Brooklyn, NY 2:59 pm. USPS tracking number actually works for international mail and if you sign up for email updates, these are very detailed and timely, unlike for domestic shipments.
