For the price that is asked for this device, I consider the shortcomings described above to be critical. For people who care about details and impeccable comfort, the device is clearly not worth the money. In my experience, it's better to take g502 (my previous mouse; + - the same, only without a docking station) or g604 (my working mouse; heavier, no backlight, slightly worse sliding due to small legs). They are much cheaper and the "set of flaws" is comparable to the price tag.
