1. A sensor that never loses the plot
Owners call the G305 sensor supremely accurate with no hiccups, while the M602 is flagged for frequent spinouts during tracking. In a gaming mouse that is the one part that cannot flake, and here it is not close.
2. Skip battery changes for months, not weeks
The G305 runs up to 250 hours on one AA, stretching to months in endurance mode. The M602 taps out around 70 hours, meaning far more mid-session charging or swapping for the same job.
3. Built to outlast the warranty sticker
Multiple G305 owners report six-plus years of daily use with no real decline. The M602 has reports of deterioration concerns well before that mark, a real gap for something you touch every day.
4. One reliable mode beats three shaky ones
The M602 markets 2.4G, USB-C and Bluetooth, but Bluetooth adds latency gamers do not want and reviewers note the RGB mode logic is fiddly. Unless you truly need one mouse across three devices, that spread of modes is not winning you anything at your desk, and most gamers just want the one link that works.
5. Yes, the M602 has more buttons and RGB. Skip it anyway.
More backlight modes and a higher DPI ceiling sound like more mouse, but 8000 DPI is unusable noise past what any human aims with, and RGB does not fix a sensor already called unreliable. The G305 spends its money on the part that actually matters every click.
