Pros: i've had this mouse for around five years and its amazing +great battery life +/- sufficient wireless range +feels amazing on the hands (unless you have big hands as this mouse is a bit small) +great price +durable (after 5 years of use only sign of wear is the rubber thing on the sides is a tad dirty) +great for gaming

Cons: - if you plan on using this mouse far from the receiver get a different mouse

Overall Review: the battery life is so long that when the battery finally runs out i always think the mouse itself is broken
