The keyboard is really nice to use. The fact that he mechanically without being noisy as the Razer Blackwidow is very advantageous (not bother anyone on TS or another because of the noise of keys) and enjoys a very heightened sensitivity (may be disturbing to some but I love ). To the disadvantage, I would note especially the lack of possibilities of software. In fact, I thought I could customize the brightness of the keys (select the ones that I wanted or apply a lighting scheme as can RGB). Only the customization of macros is possible with the K95 software ... If you want a silent mechanical keyboard good performance and with macros and do not worry about customizing the lighting, this keyboard is for YOU! : D
