Been using it for quite some time now. Overall very satisfied, except the LEDs are not really good quality (read: they are very low quality). Set everything to the brightest white and you'll see what I mean, some zones are blue and green instead of white. Not nice. I got around that issue setting a different color for these zones, but still, it takes away a lot when you want to use white.

I've found this baby to more than meet my needs for the past several months. Price is right, ergonomics are right, and there is a noticeable difference between 4k DPI and 8K DPI, although you can go to 16.4K DPI, if you want. Feels nice in my somewhat large hand, too.

Nice review. I've been using this mouse for gaming for several months, and I'm pretty satisfied with it. Can't really ask for more.

Have one, the scroll whell button broke after 2 months

Just a PSA, the latest drivers for this mouse (released Feb 2017) do not allow you to create macros that include the Ctrl, Alt, or Shift keys. Linky: http://www.gskill.us/forum/showthread.php?t=14240
