This is the mouse I have and I love it. It has a charging station which saves me money. My hand fits nicely around it. The problem is I bought this thing my freshman year of college and it's dirty and losing accuracy. So why aren't all wireless mice being made rechargeable? I can only find one Logitech model and it's $100. That's how much I paid for this mouse and it came with a wireless keyboard. I've even found some stores selling refurbished versions of my mouse. Can it really be that Logitech only made one model since 2003? I want a nice mouse. Advise me. Quickly.
