Level design, no complaints: slap. The screen a small effect, the backlight also (although I find it unfortunate that the intensity is not thereby adjustable. Next to my keyboard and my mouse macro whose backlight is flashy, makes a keyboard little pale).
Setting level macro keys, nothing more simple. This is a keyboard that has well in hand.
Very good option: the lock is quite convenient. The knob on the top right for volume control and mute button are super helpful. The two USB ports on the back of the keyboard are also super helpful (especially for people who, like me, do not turn off the computer but below the desktop).
BUT
Frankly few applications for the mini screen. It's a little disappointing. So, there really has one side "gadget" a shame. Evil untapped potential.
Many bugs !! Many users complain of problems with this keyboard. Many compatibility issues. Personally, I use Windows 7 Ultimate 95% of the time the keyboard works great. By cons at times, some bugs appear:
-The keyboard is not responding at all> compulsory hardreboot
-a key on the keyboard when released continues to be activated, "ffffffffff ..."> also hardreboot
-this time I had a problem with the mini screen also: forced to rummage manually in the computer to recover applications that were starting over on the screen automatically.
Anyway ... we expect perfection for that price. This is not the case.
it's still a good keyboard, but expect to restart your computer manually more than once if you make the acquisition.
For informed user.
