Neutral:
With two very heavy batteries, reducing the sliding dramatically on certain mouse pads. With a single battery (mouse still fully functional) just fine. See. Logitech MX 518. matter of taste.
Cons:
- Thumb has little space and my fingers slipped under the side always hot key, which is very unpleasant and the main reason for my return.
- [...] Processing the side buttons and sensitivity control seems cheap and wobbly.
- Mouse works in desktop mode unresponsiv and overrides. Sampling only at 100Hz. Comparable with cheap sensors favorable models.
Anyone who believes that the own thumb with the rubbing hotkeys (have rather delicate fingers) should absolutely access copes without this shortcoming (and the marbled processing), the G602 is gorgeous.
