Hey guys, just wanted to let you all know about the G602.
I am a avid FPS'r. BF3, BF4, Warface. That is pretty much all I play. My previous mouse is a MS Sidewinder X8. Loved that mouse and it still works good after 4 1/2 years! Well after seeing the layout of the G602 and those 6 side buttons I had to have it. I was first leery of "wireless" due to the precision that is needed in FPS gaming. Previous wireless mice that I've used all had considerable lag in FPS gaming. Granted, that has been years and years ago.
I went on Logitech's website and posted some questions about the mouse and it's "precision". I got a couple of reply's, one from a Logitech guru. He had done some testing with the mouse and found that it was just as fast as wired mice. He assured me that I would not notice a difference between the G602 and other wired mice. I bit the bullet and picked one up.
Needless to say, I'm glad I did. The very first thing I noticed was how precise the mouse was. It was actually much more precise that my ol' trusty Sidewinder. There is absolutely NO LAG in FPS Gaming. If you guys are thinking about it, get it. You will not be disappointed. I love it, having the extra side buttons are great.
Oh and one more point. In performance mode the mouse is supposed to have 240hrs of use. In eco mode something like 1400. I played in eco by accident for probably 30mins and I could not tell a difference in performance...
