The G402 is fairly close, including rubberized sides, which they removed on the G400 mice (hated that). It has less buttons, if with a claw or hybrid claw grip, though. Slightly different sensor feel (more precise on my cloth pad, and not as rough when moving fast), but no acceleration or filtering below 2000 DPI (either at or over 2000 DPI, it gets smoothing added, I don't recall which). It and the G502 (different shape) both have pretty much perfect lift-off behavior, as well, due to a gyro. If you go too fast, the gyro gets used instead of the sensor, which gives some acceleration, but that requires >2.5m/s movement on the G402, and can be turned off.
(...) just right acceleration options (...)
It had none. That was one of the reasons to buy it, even with angle-snapping (which I found hard to get used to
not having, actually, after so many years of using the MX5xx mice
🙂).
Slight rant, why do mouse manufacturers these days go for these super-high dpi settings that 99% couldn't use if we practiced?
Marketing, and high-res displays. DPI shifting is good feature for 4K general use. But, even the mice can't use their rated DPIs, 99% of the time, on most surfaces. They get jerky, jittery, have bad lift-off, jump about when not being moved...the reality is that very few high-DPI mice can be used well at anywhere near their highest settings. For the most part, it's that larger numbers are better for marketing.
