5 out of 5 eggs6 ft USB 3.0 ext. cable

Pros: sturdy build/heavy cable
6 ft. length
all black
works exactly as it should to full USB 3.0 spec

Cons: none

some people might not like how stiff the cable is, but it's not horribly so and is pretty much standard for USB 3.0

Other Thoughts: I have half a dozen of these now in use in various places. Some are on USB 2 ports, others are on USB 3.0 ports, and they get moved around at need. They always move data at maximum performance for the port they are on.

I use several hubs on these (also both on USB 2 & 3.0), my favorite being the Tek Republic TUH-300 USB 3.0 4-port hubs (NewEgg Item=N82E16817659002). I connect a couple dozen devices over this combo, many USB flash drives of 2 & 3.0 spec I've collected over the years, half a dozen external HDDs and SSDs that are also both USB & 3.0 spec, and in some cases wireless dongles for mice & keyboards.

The 6 ft. cable is fantastic to place these hubs on my desktop and reach the back of my computers. Often there is an extra foot or more available, so I coil it around the base of my monitor stands for stability & convenience.

By now I've replaced nearly all my USB 2 extension cables with these. In some cases I connect a USB 2 cable (I have a few 6 ft, & 10 ft.) to the computer and then daisy chain one of these USB 3.0 cables to it for total extension of 12 to 16 feet. Data transfer is flawless at max specification for the port every time.

I've connected SSDs and 2.5" notebook spin HDDs in external enclosures to this cable (through the hub, which is unpowered) and they have always worked on the power provided over the USB 3.0 port. I don't even remember data transfers failing when connected to USB 2 ports.

Very happy with this product; I just wish they would charge a single shipping rate when I buy multiple cables in one order. Kind of a ripoff to multiply the shipping charge by three when I buy three cables and they're all in the same package and it doesn't cost them any more to ship than a single cable. that is actually very irritating ... but that is a vendor scam and has nothing to do with the manufacturer and the quality of the product.

1 out of 5 eggsHaven't gotten it to work

Pros: Length of cable

Cons: My computer cannot access data on drives in my USB 3.0 docking station when this extension cable is used. The computer recognizes the drive, but when I click on a folder, it gives a message that no data can be found (even when data is there). The same occurs when I connect the extension cable to my USB 3.0 memory stick. The docking station and memory stick work normally with data visible and accessible when connected directly to the USB 3.0 port on my computer. I haven't tried it with USB 2.0.

5 out of 5 eggsSturdy

Pros: This cable is plenty long to extend a rear usb 3.0 port to the front of your desk for easy access.

The cable appears to be built well and is on the thicker side, nice and sturdy.

Connections fit tight/snug. Runs my devices at their rated usb 3.0 speeds.

Cons: None

Other Thoughts: This cable was cheep and got the job done. No more turning my tower sideways to get to my rear usb 3.0 ports.

5 out of 5 eggsWorks, good price

Pros: It is simple, does its job, has a very good price, but doesn't look or feel cheap.

You're not sacrificing quality or function to buy this cable. I get full 5G data rates across it when using it as an extension to another usb3.0 cable and then hub.

Cons: It doesn't have gold connectors or flashy lights... I don't really want those things.

Other Thoughts: If you're looking for gold-plated connectors, then you must either plan to use this outdoors near salt water or in a similarly corrosive environment, or you have chosen to show off your wealth in a very sad way. USB is a digital protocol, and with that said, 5 gigabit speed is 5 gigabit speed, no matter what you're putting in those bits.

If this cable is the right length for what you need, then I recommend you buy it and save the rest of your money for something else.
