i have this mouse, coming from my awesome Roccat Kone Aimo, it's a bit odd to get used to, but with a bit of practice it should be fine, the problem i have is the software, it indicates you can UN link the 3 lighting zones and set them independantly, I have not been able to do this, it all just sets to the same colour, another flaw is the key mapping, sometimes it just refuses to accept a shift+ setting, and when you click 'apply' it reverts to whatever you have set the non shift+ function to, most notably in the scroll wheel left/right functions, hopefully these little annoyances will be ironed out as the software progresses.
