A4Tech RP-1557 2-Tone 3 Buttons 1 x Wheel USB RF Wireless Optical Notebook Mouse - Retail

Have not used it long enough to test battery life.

GREAT! 1) Comfortable... 2) Great wireless range 3) Tiny, as well as the USB adapter 4) No drivers needed and detected immediately 5) Great price from newegg... Highly recommended.

A little smaller than what I expected, only about W 2.5in and L 4.5 in Comes with a charger and 4 rechargable batteries, which only 2 are needed, and the other 2 can charge through your USB while you use it.

For the price, I really have gotten a lot out of this mouse and I like it a lot. It might not be the best one out there but for a college student on a limited budget it definitly serves it's purpose and is worth every penny. .
