Good product but beware the Mac compatibility

This device is very interesting for gamers, it allows you to program actions on shortcut keys, it is possible to simulate keystrokes, mouse click and even more Script. Although drivers are available on Mac and whether the device is compatible Mac I have not been able to map the numeric keys on my keyboard blutooth apple which is especially annoying since used in many games. After hours of searching, no solution, thus returning the product SUPER treated effectively by Amazon, thank you Amazon. On the other hand, for RTS like Starcraft 2, the number of keys to use is very important and I doubt it is finally possible to do without a keyboard ... so I exchanged against a mechanical keyboard, especially for the mapping problem of some keys.
