==Matias secure pro unique features==
What makes ''Matias secure pro'' unique and/or different from [[Matias mini quiet pro]] are the following features/characteristics:
* the ''secure pro'' is a wireless keyboard;
* the wireless connection is a secure wireless type using 128-bit AES encryption;
* all 3 built-in USB ports are charging ports only (for example, attaching a mouse to the keyboard's USB port will not do anything)
* the keyboard functions only when the wireless battery is charged and the nano receiver is attached to a computer's USB port (this means, no dual, wired/wireless mode of operation -- wireless only)
* the <code>CapsLock</code> backlight does not have a typical <code>CapsLock</code> function, but rather serves as an indicator for the wireless status (charging, a brief OFF/ON light, needs charging, etc.)
* there is an ON/OFF white button on the back of the keyboard that turns the wireless ON or OFF – use it frequently or whenever the computer is idle or OFF to save the charge
* this keyboard is relativly a new product (early 2015) so the question of how long one charge lasts still remains unanswered -- Matias states that one charge should last between 6 and 12 months. The user who follows the printed guide and remembers the ON/OFF button for wireless will get significantly longer usage on one charge. In my limited testing, a fully charged battery gets at least two months with a relatively heavy usage. Also, a fully charged battery loses very little of its charge over almost 6 months when the wireless is turned OFF and keyboard is, basically, either not used or is stored – 1600 mAh rechargeable battery. To (over)simplify:
** initially charge the battery for 5 hours;
** turn OFF wireless whenever not typing; and
** if this is your only keyboard, make sure to charge it before the charge is completely depleted – you can use the charging cable while typing
* there is no perceptible lag between typing and the letters appearing on the screen that is sometimes reported with wireless keyboards – 200 Hz polling rate
* the ''secure pro'' is just slightly heavier than the wired "mini" Matias keyboards (by about 40 g) and weighs about same as ''Matias laptop pro'' keyboard
