The controller is very similar in direct comparison to the original X-Box-One controller in its quality. The surface is designed slightly better in MS, because matt and not shiny. Otherwise, the control buttons are good, the pressure points OK The volume buttons are actually a sensible addition to the buttons. The big disadvantage when operating on iMac, however, that Mad Catz only the operating system OS support in the drivers 10.9, but not the actual Yosemite OS 10.10.2 (like mine) or the very latest 10.10.3. Games can not be controlled so. Unfortunately, could not say how long it will take to update the Support of Mad Catz. It is therefore advisable before buying (of course with Windows PCs) to check only on the manufacturer's website, the timeliness of the driver, before placing the order.
