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.

Pros: -Works exactly as intended.

Cons: -None.

Overall Review: I needed a cable to turn my front side USB 3.0 ports into 2.0 ports due to my motherboard not having 3.0 ports for the front side and it worked exactly the way I wanted to so far.

Pros: Easy install Not expensive

Cons: Nothing about the adapter

Overall Review: This was no-brainer to install, and both USB ports tested fine. While the description does say 5-15 days..(it was 14 for me), I would hope that Newegg would carry a few in their warehouse (just put them in someones desk drawer...hehe) if only because they are so small, and someone might need them in a major hurry (I was that person).

Pros: Bought this for my wife's computer. Her motherboard only had USB 2.0 headers. Her new case's front ports were USB 3.0. Put this in and the front USB ports work perfectly now.

Cons: None.

Pros: Fit like a charm and did what it was supposed to do. I didn't expect it to end world hunger.

Cons: Product itself, fine. It must literally have come over on a slow boat from China or from a galaxy far far away. Be sure and tell the grandkids in your will to be watching for it. It'll arrive any day now ;)

Pros: Does its job.

Cons: Not Free

Pros: This little Adapter will convert any extra USB 2.0 headers into a single USB 3.0 Header, not the other way around. Obviously, you will not be getting USB 3.0 speeds by using this, as it relies on the USB 2.0 header, and simply converts it so it is able to be used with any USB 3.0 header female connections. On the cable, the USB 3.0 Header is MALE, while the USB 2.0 Header is FEMALE, to clear up any confusion. Item seems sturdy enough. Will edit the review should anything about this item change in the near future.

Cons: Item is not 100% black, as right before the USB 2.0 Header, there are some exposed colored wires. Not too big of a deal, they could have just brought the shrink wrap up a bit more, or used black wires. Item may take some time to ship, it is shipping from China. None of these cons effect the actual usage of the item. Will update review should that change.

Overall Review: Overall this solved my problem of having one too many USB 2.0 header connections, and one to few USB 3.0 header connections. And it was cheap!

Pros: -ability to use usb3 port with usb2 motherboard connection

Cons: none

Overall Review: Adapter was used to convert a single usb3 19 pin female connector on computer case to usb2 front panel connection on motherboard without usb3 support. Note: this adapter only allows a usb3 port to operate at usb2 speeds.
