Pros: Holds the battery for a long time, but this is not particularly important, because. thanks to the docking station, you will forget about it, much more convenient than mice with batteries or requiring direct charging. It catches perfectly, when playing on the TV, the mouse is meters from the base and catches perfectly. Connection breaks, the low probability of which some reviewers mentioned, were not found, everything is stable in shooters and other games. On the sides there are no sharp ribs or elastic bands that will get stuck in dirt or peel off. The soft touch plastic coating is also absent, which I consider a plus, it will not be erased over time and does not get so dirty. Has some cons: Maybe not the most premium plastic, but the top-end sensor, base, connection quality and other advantages for their price interrupt this nuance. I would consider the software as a disadvantage, it is unnecessarily heavy, requires the installation of applications within the application itself, i. E. you need to install a backlight control application in order to configure it, without it the program does not work with it. In my opinion, this is an over-complication of the software. But I rarely use it, so it's not critical.
