## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Functional and Reasonably Priced
  

*by J***S on Reviewed in the United States on July 29, 2014*

This is a wonderful little device at a reasonable price. I use it to connect my Microsoft Surface Pro 3 to the ethernet at work and provide extra usb 3 connections.  It works perfectly in both functions with no performance penalty that I can discern. Difficult to imagine a product that does what this does more efficiently and at a better price.

### ⭐ 1.0 out of 5 stars







  
  
    frustrating at best
  

*by E***X on Reviewed in the United States on June 28, 2014*

It took so long to ship, that I thought the order had been cancelled due to a message in my account saying they were out of stock.  Due to this message I ordered a new one, then a day later I was informed the original had shipped.  Thinking it was the second one I ordered, I just waited for it to show up.  I received both a day apart.  On a side note, my friend ordered one the same time and his showed up quickly and without incident.  So now I have 2, not a terrible thing until I attempted to use it.  It is extremely touchy with network connections on my Mac, I had to adjust the connection speeds until it finally connected.  I also discovered that if it is plugged in, my wireless connection fails to connect to anything.  Finally, my friend is unable to plug his mouse into it and have it function more than 2 inches from the unit.  I seriously wish I had not purchased this (at least not without an additional power supply) let alone 2 of them.  I would avoid this vendor and this product.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good performances and ethernet works fine
  

*by J***E on Reviewed in the United States on August 11, 2014*

I bought it to replace the non-working docking station I had and to replace my old HTC usb2.0 hub.The device works perfectly.A small issue is the use with a Surface Pro 3 because the cable is so short that the usb port position which is so high.. put the hub to be floating in the air.
