Logitech Signature M650 Wireless Mouse vs Logitech MX Master 3S
Get the Logitech MX Master 3S. Unless you want to spend as little as possible, or your hands are small — then the Signature M650.
Logitech Signature M650 Wireless Mouse
A cheap, well-built, contoured work mouse with quiet clicks, in a regular size, a large M650 L and a left-handed version. Not vertical, and no thumb wheel.
Logitech MX Master 3S
Nearly the same comfortable shape, MagSpeed wheel and quiet clicks as the MX Master 4, for less. You only miss the haptic panel and shortcut ring.
