1 out of 5 eggsSTAY away

Pros: GB Ethernet, Light Weight, LED Indicators

Cons: DEAD after just a few months. Attempting to RMA now. Feels very cheap, low quality. R&D was probably less then an hour. Sad to see SIIG products so unreliable.

1 out of 5 eggsCrapped Out After 4 Weeks

Pros: It worked for a little while.

Cons: Poor quality.

Other Thoughts: I hesitated to purchase this because I haven't had many good experiences with SIIG products. However, the reviews I read indicated this was a winner. I wish I had listened to my instincts and went with a different manufacturer. This unit worked for a little while - 4 weeks, and then it just stopped. What a waste of time and money.

5 out of 5 eggsPlug and play on Linux

Pros: Plug and play on Ubuntu Linux 12.x (could care less about Winblows)

USB 2.0

Extends the life of my aging HP DV-6000 laptop.

Transferring files across my LAN is now *much* improved.

Cons: Can't think of any.

Other Thoughts: Just what an older laptop with 10/100 networking needs.

Most machines of that generation also lack USB 3.0 but have USB 2.0 ports.

Good job SIIG!
