All of the drawbacks, such as the fact that there is no sensitivity setting, are entirely based on personal preference. I use it at 7000 dpi, but I don't have adequate cursor accuracy; maybe it's hidden somewhere in the parameters that I can't discover. A fairly audible click. I never use the button to change the dpi on the fly since I find it to be completely worthless. Very light for me, but I absolutely adore heavier mice, and unfortunately, manufacturers no longer honor them as an option. In general, the mouse is a rather comfortable average mouse that does not cause global negativity. However, because I prefer a palm grip, I do not have sufficient bend in the mouse. The previous roccat horse survived for 6 years, just like the first naga before it (although it seems like it lasted even longer, perhaps 8 years), and I am hoping that this one will live for at least 4 years, considering how much it cost.
