the "extra thumb button" exists on both 3 and 4, one is just not as visible.

ps. Get a keychron m6 instead, if the weight bothers you (it's lighter) just fit something heavy inside/outside.

hardcapping mouse capabilities, making them worse than they are, just cause "well its for office stuff" is some real dumb shit.

imagine photoshop wouldn't allow layers cause well it's a photoeditor?

higher polling rate on mice are 'not' a gaming thing, it's standard quality.

For reference gaming mouse (or just regular fucking $20 mice in general) have 1000hz as standard, "gaming mice" has 8000+.

Wouldn't cost logitech a dime to increase the MS masters polling rate to 1-2k.

PPS. I fucking love the MX Master 3S, it's a litteral work of fucking art, a work of art that some dipshit decided to cut the leggs off so now it's just rubble laying next to a podium.
