Logitech G Pro X Superlight VS Logitech MX Master 3S
Verdict BUY IT BUY IT
The Reality The under-63-gram weight figure itself is real and independently confirmed by multiple reviewers and retailers -- roughly 25% lighter than Logitech's own standard PRO Wireless mouse. But 'lightest wireless gaming mouse' as an absolute, category-wide claim needs a caveat: competing mice, like the Razer DeathAdder V3 Pro, land in the same weight class without using a perforated honeycomb shell. Reviewers characterize the Superlight's real distinction more precisely as the lightest wireless gaming mouse that doesn't rely on a honeycomb design to hit that weight, not the single lightest wireless gaming mouse on the market outright. An independent teardown comparing the MX Master 3 to its predecessor reached 216 points and 189 comments on Hacker News — real engagement, but noticeably smaller than the Steam Deck or Framework Laptop threads checked in this same batch. That's not a red flag for a mouse (peripherals rarely generate hardware-launch-scale hype), but it's a fair, honest comparison point worth stating plainly rather than dressing up as bigger than it is.
SHORT ANSWER
Logitech G Pro X Superlight: The G Pro X Superlight's sub-63-gram weight is real and independently confirmed, but calling it 'the lightest wireless gaming mouse' overstates it slightly -- competing mice like the Razer DeathAdder V3 Pro land in the same weight class without a honeycomb shell.
Logitech MX Master 3S: The Logitech MX Master 3S has real but modest Hacker News engagement (216 points, 189 comments on an independent teardown) — genuine interest for a peripheral, though far smaller in scale than major PC/laptop hardware launches.
