If you’re going to be using your computer for any meaningful amount of time, you’re going to want an external mouse. Nowadays, Bluetooth is the way to go. Gone are the days of having to use up an USB port on a receiver. This Logitech M557 Bluetooth Mouse is a great mouse from Logitech which offers 1 year battery life and a fairly small form factor. I like that the scroll wheel has additional functionality in having a lean left and right button.
This is the Bluetooth wireless mouse you can rely on to work flawlessly with whatever platform you work on—Windows, Mac or Chrome. Plus it’s loaded with features that make it a breeze to navigate documents, the web and your favorite apps. Go for up to one year on two pre-installed AA batteries. An On/Off switch helps conserve power, smart sleep mode extends battery life, and an indicator light eliminates surprises.
