Pros: Would make a good paperweight. Or maybe a boat anchor.

Cons: Doesn't work. Had mine plugged in and my computer would not boot. If you plug it in when it's running, it will work but anytime you restart the computer with this hub plugged in, it won't boot. I will be returning this and buying from another company.

Other Thoughts: Expensive and doesn't work. Unless you need a paperweight. Short USB and power cables.

5 out of 5 eggsWorks GREAT!

Pros: Great speed / plug and play / very easy to use.

Cons: None so far.

Other Thoughts: I purchased this product to work with a Seagate USB 3.0 external drive. I did not have a USB 3.0 port in my computer so I also purchased the USR8402 PCIe card for my desktop machine. This combination has provided HUGE performance gains for my hard drive over USB 2.0. Have used USR products in the past and go the same solid performance as before! I would recommend products from USR.

1 out of 5 eggsFails to support USB 3

Pros: small and compact - too bad it didn't perform according to specs.

Cons: Hub plugged directly into USB 3 computer port which successfully runs USB 3 drives. USB 3 drive plugged into hub could only run at USB 2 speed even though it was the only peripheral using the hub and the hub was powered. When I plugged the drive directly into the USB 3 port on the computer (removed the hub), it ran at the correct speed.

This rather expensive hub was unable to support a WD 1tb, USB3 drive at anywhere near appropriate speeds.

Returned for a refund. Disappointed in USR but wont try them again for quite a while.

Other Thoughts: The electric plus is a large block with a very short cord.

In truth, aside from the good looks, I can't say anything good or even acceptable about this product.
