The keyboard is just parfais compatible with the Razer Synapse software (which is really great is optimized the way =) Mechanical keys are very pleasant to use only downside (which for me is not one) is the noise Key but I like is a matter of taste. / ATTENTION \ The keyboard shown with the backlight is the Ultimate model which is an error, it will be good from the Amazon to correct this little detail because it is indeed the BlackWidow 2013 and not the BlackWidow Ultimate 2013! On this great game has all the lucky ones who have this keyboard GL HF!
