What to know about the Logitech MX Mechanical
Aimed at productivity rather than gaming, with quiet tactile switches and multi-device Bluetooth/Logi Bolt pairing — useful for checking that a board optimized for quiet typing still registers every key cleanly and consistently.
These are general notes about this switch/connection type, not a substitute for the live test above — behavior varies from unit to unit. Run the test on your own board to see what yours actually does.
