After 7 years we decided it was time to upgrade our old iMacs to the 2017 version. But now both the USB ports and the SD card slots are on the back of the new "thin" computers and it's too inconvenient to reach them. These Satechi hubs are a great solution for us. Their materials and style match the iMac perfectly, and the build quality is superb. The cable is long enough to reach one of the rear USB ports but not so long that it gets in the way as you can see in the attached image.
