The Take
The Logitech MX Master 3 feels premium in the hand with its MagSpeed wheel and seamless three-device switching yet locks buyers into disposable hardware.
Chinese manufacturing and non-repairable internals turn a productivity win into another upgrade cycle that benefits the landfill more than your wrist long-term.
The Verdict
Ergonomics and switching earn praise but the glued chassis and supply-chain reality make this a short-term tool at best.
Skip the upgrade cycle. Buy a used MX Master 3S or keep the original — one purchase, years of service, no subscription tax.
