An absolutely fantastic gaming mouse. Works great with all I have played so far. The ability to adjust the DPI value is very useful, in sets of 500 up to 4000 with the software included. Changing between one mode and another is an easy click of a button, although this does use up two of the customisable buttons(and another two for left and right click, although DPI mode can be changed manually with the software).
As the mouse is pretty much ambidextrous(although left handed people have to use the other two customisable with their ring finger) I wasn't sure how it would feel. Once I tried it, I found it comfortable, and I quickly got completely used to it.
The mouse visually looks great, I love the burnished effect on the copper, while the light options(pulsing and brightness) add an extra nice aesthetic. Individually changing the DPI value for each colour using the software gets round the supposed pink mouse problem. For example, I currently have red with the most DPI, and pink with the least.
I am currently using the customizable buttons for copy and pasting, really useful when browsing the internet. They also have the ability to execute macros, but I haven't used them yet. There are options to have different profiles for different games, while the advanced settings allow the changing pointer speed and tail like window's mouse settings, scroll speed and the ability to adjust the mouse's polling rate(how often the mouse sends info to the computer, the higher the greater precision)
Overall, I am thoroughly pleased with this mouse and would definitely recommend.
