1 out of 5 eggsCable inoperative

Pros: Received order quickly.

Cons: Received 4 days ago, used one time successfully. Using today and cable ceased to work. Computer doesn't recognize thumb drive which still works without cable. Useless to me now.

5 out of 5 eggsGood cable

Pros: It extends the USB 3.0 from the back of my PC so I can use it on my desk (My case has no 3.0 front headers)
The quality is quite nice.

Cons: None, considering it was only $3

Other Thoughts: USB 3.0 cables are definitely thicker than USB 2.0 cables.

2 out of 5 eggsInconsistent quality

Pros: One cable seems to work fine at USB 3.0 speeds with an attached USB 3.0 hard drive.

Cons: A second cable ordered at the same time works fine only at USB 2.0 speeds, and causes USB errors at 3.0 speeds when transferring data to/from an attached USB 3.0 hard drive.

Other Thoughts: These cables seem to be hit-and-miss as to whether or not they work error-free at USB 3.0 speeds.

3 out of 5 eggs2 out of 3 worked

Pros: 2 out of the 3 cables I bought worked.
Short cables a big plus for reaching around from the back of the computer, without having a lot of extra cable.

Cons: 1 out of the 3 cables didn't work...well....kinda...I plugged in the first USB cable, and then a USB3 thumb drive. Transfer worked just fine. I accidentally bumped the desk and my computer made the "Your Thumb drive has been disconnected" sound. Then it made the reconnect sound. So I touched the Thumb drive with my index finger, and it disconnected and reconnected. Weird?!? So I switched out the cable and couldn't replicate the problem with the second or third cables. Put the first cable back in, and anytime I would touch the Thumb drive, it would instantly disconnect and reconnect.

Other Thoughts: Since the cable is less than $3, and shipping the bad cable back would cost more than that, I have to chalk it up as a loss.

5 out of 5 eggsGreat Product

Pros: These are great cables, they work well and the gold plating is an added bonus. Feels solid, though it's a bit thick, it works as intended. I don't have front case USB 3.0 ports so this will get me easier access to those ports I have in the back. Haven't had any issues with data transfers, works just like connected to the rear IO panel.

Cons: Might not be a con, but the cable is a bit thick/stiff.

Other Thoughts: They work as intended, price is great as long as you have a shoprunner account.
