Logitech G604chat_bubble_outlineFrom real comments

Button layout and features win over MMO and productivity users. Commenters repeatedly praise the six side buttons, hyperscroll wheel, and dual wireless connectivity for MMO, MOBA, CAD, and Excel-heavy workflows. Several call it a worthy G602 successor or a 'gaming MX Master,' assigning skills, macros, and volume controls to the extra buttons. Bluetooth switching between laptop and desktop is highlighted as a genuine convenience, and many say they can't go back to a simpler mouse after using it.

Double-click switch failures plague long-term owners. An overwhelming number of comments describe left, right, or middle-click switches failing and registering unintended double or triple clicks, often within months of purchase and recurring after warranty replacements. Fixes range from breathing or blowing into the button gap to discharge static, spraying contact cleaner, to fully desoldering and replacing switches with Omron, TTC, or Kailh alternatives, suggesting a widespread hardware quality issue.

Disassembly is described as needlessly complex and rubber grips degrade. Multiple users attempting switch repairs describe an excessive number of screws, tiny loose springs, and fragile flex cables, calling the internal design 'over-engineered' and far harder to open than the older G602. Several also report the rubber palm and thumb grips peeling or disintegrating within under a year, compounding frustration with a mouse otherwise liked for its features.
