5 out of 5 eggsWorks well

1 out of 5 eggsDOA

Pros: Would have been nice if it had worked

Cons: DOA. Defective cable caused the USB device to "drop" constantly.

Other Thoughts: Between shipping and return cost, cost more to return than to throw in trash. Shipping should be covered by NewEgg/Vantec when sending DOA device !!

5 out of 5 eggsWorks as advertised

Pros: Runs at USB 3.0 speeds, able to max out my suboptimal comcast internet. Easy installation, simply plugged it into my laptop and windows 7 automatically detected the drivers.

Cons: Was hoping it would be less bulky since I have limited desk space.

Other Thoughts: Wasn't working at USB 3.0 speeds initially - HWinfo said that it was operating at USB version 2.10. However, the problem turned out to be that my USB ports were using USB version 2.0 still - updating the chipset drivers on my HP laptop fixed it!

5 out of 5 eggsThe Best

Pros: It does what it says. Connecting to USB 2.0 still makes it ~300Mbps transfer rate = ~30mbps while transfering files between computers, instead of using 10/100 ethernet port, which makes it ~10mbps

Cons: Have to install driver from CD before actually using it. What if you don't have CD? Have to find other means to get the driver.

Other Thoughts: All in all, it's really good.

5 out of 5 eggsFast

Pros: Fast, operates at full gigabit speeds, setup relatively easy.

Cons: From Win 8.1 U1 you will need to run the setup from CB-U300GNA\Windows\Win8\Win8_setup.exe. I tried running it from CB-U300GNA\Windows\setup.exe and got a message that the OS was not supported. Also, make sure that you install the driver before connecting the adapter.

Other Thoughts: The manual may need to be updated for Win 8.1 U 1. Thought about dinging it a star for this, but really it operates well enough to deserve 5.

5 out of 5 eggsWorks Great

Pros: My ultrabook does not have an Ethernet port and this item fits the bill. Works just as advertised. Very satisfied.

Cons: None.

Other Thoughts: Out of the box this item will not work with Windows 8 64 bit. Be sure to get the newest drivers off the manufacturer site and you will be good to go.

4 out of 5 eggsNeeds a user manual tweak

Pros: Windows 8.1. The device came with a driver CD. When I tried to install the driver, I got a message that my system is not supported. Grrr. I was about to complain when I decided to just plug the thing in. It works.

4 eggs instead of 5 for misleading documentation

Cons: Documentation a little inaccurate. I can live with this.
