(From my review at Examiner.com)
Roccat’s IskuFX gaming keyboard has all the power and versatility of its blue cousin, but adds a little more color to the already impressive Isku keyboard.
But aside from the additional color options and support for a reactive lighting system called TalkFX, the IskuFX is otherwise identical feature for feature to the Roccat Isku. (I won’t rehash all same features here, so if you want more you can read my complete review of the Roccat Isku here.)
