A little big at first, this hub is actually extremely convenient. It adapts to Mac and PC, what I need yet being forced to use the PC to the regulatory work, although I make the esentiel of my work on Mac, and even on the TV which has a only USB. I have one on my MacAir, so this a TV in my office and US (purchased on Amazon.com). All functioning perfectly well, with a very ergonomic design, both plugs presented on top of the device for connecting the keys or peripherals we use with other instruments. Perfectly satisfied with the product, great value. I also recently purchased a USB 3.0 drive that works perfectly on the Hub. Probably not as fast That a 3.0 hub but being given the choice of 3.0 hub compatible with mac, it's not very serious.
