Rating: 5/5 Great July 17, 2016 I bought this one to use with my MacBook Air and it works perfect, I am using 2 64GB 3.0 Flash Drive at the same time for DJ and I do not have any issue with it yet. I believe this is the best Hub that I have used so far.

I will recommend this product 100%.

Rating: 5/5 Never thought I'd need this... August 30, 2015 Thank you OWC for carrying this item. I never thought I'd need to have an ethernet dongle again given the current trend to use WIFI on every Mac and PC product. I travel quite a bit for work and sometimes WIFI isn't available or the signal strength is poor. In those instances, when available, I'm glad I can turn to an ethernet jack when I have to. Buying an ethernet to USB dongle seemed so backwards and it was yet another device to have to carry. It was a welcome purchase to be able to get rid of my old USB hub and by this version that happens to have an ethernet jack as well. Great combination. Thanks again for carrying this product.

Rating: 4/5 Works as advertised October 2, 2014 Even better than the Apple USB -> Ethernet adapter because the Apple one is only USB 2.0 and 100BT, but this one not only is USB 3.0 and 1000BT it also gives you extra USB ports. I'm using it with the OWC MiniStack Max on a MacBook Pro, and all it takes is just one USB port and everything is connected.

The only drawback is that the USB cable is too short and too stiff. Either too short or too stiff is OK but both make it hard to plug in tight spaces.

Rating: 5/5 Great ethernet/USB 3.0 for MacBooks w/o ethernet ports February 13, 2014 This lightweight, compact, dual-role adapter provides simple expansion and gigabit ethernet to newer MacBook Pro models without ethernet ports. Better than Apple's Thunderbolt-to-Ethernet adapter because this product also includes three USB 3.0 ports (in addition to the ethernet port). Works well and quite transparently. Installation is easy, but poorly documented. Using the ethernet port requires installation of a driver which is not included with the product, but is downloadable from the Kanex web site. The product comes with no instructions, and the warning on the package that the product "Requires driver installation for Gigabit Ethernet adapter" is buried in some 6-point type under "Specifications." The web address for finding the driver is also buried, nowhere near the "requires driver" warning on the box. (see attached image) Downloading and installing the driver is simple, but requires a restart. And the driver comes in two flavors (Mavericks and pre-Mavericks) which are obscurely identified. Once it's up-and-running on each computer where you intend to use the adapter, you won't confront these installation issues again, and the product works seamlessly.
