The Redragon M913 is excellent for MMO gaming. It has a 12-button side panel, which is fully re-programmable like most other buttons on the mouse using the companion software. It feels well-made and has a comfortable right-handed shape well-suited for medium and large-sized hands using a palm or claw grip. It has a wide CPI range, a CPI you can adjust by increments of 100, and a very low lift-off distance. Unfortunately, it has high click latency for a gaming mouse, and the sensor is inaccurate and undershoots the set CPI considerably during fast and slow cursor movements.
