[M] Mad Catz S.T.R.I.K.E. M Wireless Keyboard Review
 

S.T.R.I.K.E. M is a cool looking mobile keyboard which features smaller than usual keys, meaning that some time is needed to get accustomed with. While the product connects to the devices via Bluetooth technology, we do have one device cycle button for jumping from one device to another in just a couple of seconds, without the need of additional configurations of software. Multimedia keys are fitted on the top left side and quite a bit of functions like ESC and F-keys are accessible while working with the Fn key. For even better flexibility, we can see one OFN (Optical Finger Navigation) button on the top right side, which is accompanied by the mouse left/right buttons; an extra set of mouse buttons is also available on the left, which helps when holding the product in both hands.
