Software
The installation CD as well as the user manual are wrapped in a practical, small cardboard box, which would be hard to lose. Furthermore the latest version of the software is also available on the official website from Steelseries. A manual is always useful but it is not necessary, just connect the keyboard and then start to use it but if you want use the macros, you should definitely check out the manual. The user interface is the same as with any other Steelseries product, very minimal and with some options slightly hidden. The settings can be imported and exported, which is useful if you want to compare them with your friends.
