Matias FK318LS RGB Backlit Aluminum Keyboard for Mac

RGB Backlighting
Colour dial on the back to adjust the colour spectrum freely from white to other colours.
Backlight brightness is also adjustable via Backlight Key and +/- keypad keys.

Beautiful aluminum design with numeric keypad
Modeled after Apple's iconic aluminum keyboards, the Matias Wired Aluminum Keyboard looks & feels just as nice as the Apple originals.

Mouse-friendly (1-port) USB 2.0 hub
The built-in hub is great for connecting your favourite wired mouse (or wireless dongle) with a 2nd port available for plugging in flash drives, or other devices.

High precision volume dial
Perfect for users with external speakers, the volume dial gives you MUCH finer volume control than you get from pressing volume keys - though it has those too.
Specifically, the dial offers 64 volume levels, vs. 16 levels for the volume keys - 4x more precise.

Mac-friendly function keys
Just like an Apple keyboard, the function keys let you control screen brightness, volume, iTunes, and more.
There's even an Fn key, that lets you momentarily change the function keys back to their traditional duties, when you need them.

Legacy Mac OS support
The Matias Wired Aluminum Keyboard is compatible with Mac OS X all the way back to version 10.6.8 (Snow Leopard).
If you're running legacy software on older systems, this can be a lifesaver.
