I bought this product to increase the height of my iMac and the number of USB ports. What's particularly appealing is that the USB ports can charge my iPhone and iPad even when the iMac is off. It works as advertised, but it should be noted that: (1) contrary to the description, it's not wide enough to accommodate both a full-size keyboard and mouse, and (2) despite the attractive design, some of the components are cheap are , thin plastic. In general, more than $100 is too expensive.
