I already have the Air75 and because of its quality I was encouraged to buy the Field75. From the outset, the keyboard is very well built, although the lever to change the input (usb, 2.4 and Bt) looks plastic like the gear to change colors as well as the volume wheel. Other than that, everything looks of high quality, including the handle to hold it. which is a detail that I loved to be able to move the keyboard.
Now, there is one point that is very important and cannot be overlooked: currently it is not completely finished for Mac users. The Function key does not work to change the behavior of the F keys, even if you carry out the procedure described in the instructable. Similarly, the same instructions indicate that the software allows you to change the behavior of the G keys, however there is currently no software for Mac, so I still do not use those keys.
I think this keyboard is designed for Windows only, which I hope will change in the future so that those of us who use Mac can take advantage of its potential, since it has many functions that are not only limited to gaming.
