Since I look for a long time and compare the Internet found none that what ever makes optical ago, lighting and a pre-programmed and programmable buttons and a volume control for various applications such as
Windows Media Player. The WMP can be completely controlled via the keyboard without even touching the mouse.
The way the buttons light can be turned off and work in the dark or insulated light is the backlight of the keyboard just brilliant.
Oh and important .. works with PS2 connector, since the meissten illuminated keyboards only run properly with USB.
The BLUE ICE has but even a USB connector runs perfectly with PS2
Adapter with all functions. Important for people who two computers on a
KVM Switch operate having only PS2.
Only noticed before Mango is a slight misalignment of the scroll wheel and a USB hub for missing USB memory sticks.
Likewise some getting used to is the relatively low-profile keys of Keyboardes but I think this passes quickly.
CONCLUSION: I would buy again !!!
