I wonder why we never se a freeroll function for the wheel.... has Logitech patent protected it or what?

Given that a 300 mAh battery is used...are u crazy that's too low, put AA Rechargeable Lithium Ion battery and we can talk.
If battery dies i can replace AA with this SHEET i can throw mouse in garbage!

I'd love this too, but that functionality needs heavy magnets and more complex programming for when to engage, so unfortunately companies don't risk it.
I think so far really only Razer tried with the Pro Click series, no?

Sure, if you want a mouse that weighs 30 grams more. You straight up can’t get low weight with replaceable batteries. And the market seemingly has a preference for mice with lower weight. If that’s a dealbreaker - the Logitech G309 is that way.

This is certainly one of the cheaper Pixart PAW39xx mice you've reviewed in a while, but it's still not cheap. I miss the days when there was always an easy sub-$50 no-frills mouse on the market that had a decent sensor, no glaring issues, and modest specs like 2000Hz polling.

Still $70 for a mouse that does all this is damn good value. I'm mentally put it on the shortlist.

8000Hz is the new buzzword that has every manufacturer sending out review samples, but even some of the highest-tier eSports celebrities are at their human limits using a 2000Hz mouse. Maybe it's time for a reality-check article to see if anyone can identify an 8000Hz mouse over a 2000Hz mouse, and whether we really need to chase click latencies lower than 2ms? Given that the average high-refresh display is 144Hz-180Hz these days, all but one of the mice in the chart are capable of multiple click samples per frame, at which point how much use are lower latencies?
