Logitech Pebble Mouse 2 M350s

Why it's our Starter pick

• Pairs with up to three devices over Bluetooth and switches between them with one button; it weighs 76 g.
• Runs up to 24 months on one AA battery, with quiet clicks and a 4,000 DPI sensor (Logitech).
• Trusted Reviews calls it a decent affordable mouse for travel or the office, with a responsive sensor and buttons.

Watch out: Its low, flat shape gets tiring over a full workday; RTINGS rates it middling for desk work and says it feels cheap.
