Masterkeys Pro S RGB is an interesting TKL keyboard from Cooler Master that was thought with on-the-fly capabilities from the start (for both LED and Macro setups). Quality is ensured by using original CHERRY MX switches (Brown, Blue or Red), comes with a preset Polling Rate of 1000Hz, while the included 512KB of storage helps creating up to four separate profiles. Masterkeys Pro S also comes with the possibility to set up the RGB lighting system via software, so we do have a downloadable utility from the website; the said utility will also update the firmware on the peripheral, with just a mouse click.
