Our Verdict

Logitech Signature M650

Keychron M3

The Keychron M3 and the Logitech Signature M650 are wireless mice with symmetrical shapes. The Keychron is lighter and has much better gaming performance. It also has RGB lighting zones and an internal rechargeable battery. On the other hand, the Logitech uses an AA battery for power.
