seems like a decent mouse, with a 3395 sensor, but defiently not very customizable. Apart from the rgb sync, and unique shape, nothing very cool about it. Honestly overated if you ask me, be cheaper to go with pxnage custom mouse that you can actually, "customize" with 3370 sensors, I believe. you can change the side buttons dpi button, and the color of the entire mouse. plus change sensor position, and put in or take out special weights designed for the mouse. I know the Mercury m2 aint doing any of that lol. But overal like I said a decent mouse I might have to add to my collection.
