A mouse that doesn't function properly, even if it's not very often, would drive me crazy. 

Nope! Have one now, Never recommended!

Back when the G602 launched, I actually really wanted one. Then, for Christmas that year, my sister-in-law got me the Razer Naga Epic and I fell in love with it. Now after 4 years of hard use, the wireless function and battery charging is acting up on me and I don't know what to replace it with. I've grown to really appreciate the number buttons on the side. Would like to get another, but they're so expensive... Good thing it can be used in wired mode.  

I sort of want to get a decent wireless mouse to take with me to college, to go along with my laptop. I am using the G402 and can't complain, but wireless would be a nice feature to have... idk

Prefer wireless mice, but will use corded if need be.
