Summary: This mouse is the biggest mouse I've ever used. My hand doesn't fit comfortably over it and it doesn't feel as accurate as my G500. I do like the DPI buttons on the front, and the weight adjustment, but I still can't use it because of the size.
Summary: I was very happy with this mouse up until the right side clicker broke. Only lasted for about 4 months before this happened. I guess Diablo 3 was its downfall. Other than that it had a comfortable grip. Might be a bit bulky for smaller hand though.
Summary: Bought two of these mouses for my dual PC setup. Both mouses are having to be returned (RMA'd). Great mouse when working but having both go out in such a short amount of time is crazy. I have never even had a mouse or keyboard go back until now. So much for not sticking to Logitech.
Summary: The thumb buttons are very well placed. They sit high and have a braille-like patch of bumps under them so you can always find them quickly but you don't hit them accidentally. Scroll wheel clicks when scrolling feel solid but smooth. Sensitivity buttons are easy to hit but out of the way and the settings are useful and it displays your position in the list of settings using the red bars on the left side. You can't cycle the settings though.
Great mouse when it works, never works for long though.

Summary: I am now on my third mouse and it is showing signs of failing soon. Each one I have gotten has started to not track either vertically or horizontally randomly on and off. Its a gaming mouse so it is pretty frustrating when this happens during gaming. I RMA'd the first one I got through Thermaltake and they handled it ok, except my mouse didn't come for a while, instead I got an email saying they were out of black mice so they had to send me a white one (my original was...
Summary: I really liked this mouse. It felt great in my hand, had a good, grippy, rubberized feel to it, and performed well. Sadly, it lasted only 10 months. If I pick it up even the slightest bit off the mouse pad to reposition it, it shuts itself off for 10 seconds to a minute. The buttons still work, but you can't move at all.
