Logitech M185 Wireless Mouse, 2.4GHz with USB Mini Receiver, 12-Month Battery Life, 1000 DPI Optical Tracking, Ambidextrous, Red

I've used this same basic model for many years (or like this model) because Logitech never lets me down. They last for 3-4 years, and the battery lasts for many months up to a year. Like their other basic models, you can hear the clicking, but that's never bothered me. It fits comfortably in my hand and works smoothly on the screen. Once the USB is placed, that's all there is to it--it's good to go. If you're like me and don't need the bells and whistles, this is a mouse you can depend on for a long time.
