What's the best wireless mouse for all-day office work?

For conventional shapes, reviewers consistently point to mid-range Logitech models like the M510 and Signature M550 L, which combine multi-month battery life, silent or quiet clicks, and comfortable contours. If wrist or forearm strain is the concern, ergonomic verticals (ProtoArc EM11 NL, Logitech Lift) and trackballs (Logitech Ergo M575S) draw the strongest comfort feedback in specialist communities.
