Mouse is apparently very good, say flawless, however, have a problem that came in my unit, the button DPI is sunk and looks not work, will check after, but is the addendum, Not know if was a problem with my unit or all other mice comes with this problem, but looks like it was an isolated case. Taking this fact, like the footprint, side buttons please me quite, both with 9 buttons as normal with 3. The two sides footprints right please me, especially that comes with support finger, this was perfect for me. Mouse is somewhat heavy compared to MRU G203 of Logitech but ever imagined. Sensor PMW 3325 will give account work without problems. Braided Cable the Nylon is horrible, but as is a mouse MMORPG (with various buttons) ever notice that the cable is not the focus, think until they do this thinking in durability mouse wire, but be horrible. Still loved the mouse. Recommend
