Let's make this snappy:

1. Ergonomics aren't great – doesn't fit in my hand perfectly, but it's close… ish.
2. The laser is positioned toward the front of the mouse – because it's not in the middle, I find it makes small adjustments difficult. Hopefully it's something I can get use to.
3. The three buttons on the left click are a bit too far back – I find G8 particularly hard to reach if I ever needed it.
4. Tilting the wheel to the right is incredibly easy to do by mistake – there's almost no resistance (though oddly there is if you want to tilt left).

Besides those little niggles, the mouse meets the high expectations set by it's high price. There are few, but nonetheless, some, better mouses available for this kind of money.

This mouse lost it's charge very quickly and the response in gaming was poor to say the least. I moved to the Roccat Kone XTD and have been very happy with it!

I have had a G700 since they came out but I won't be buying another. The mouse is comfortable and the extra buttons are easy to program and use, but if you are using it wired and then unplug the USB cable to go wireless the thing fritz's out and says a keyboard key is continually held down and you have to reset your PC to fix the issue. It has been a common problem for a fair amount of time and Logitech haven't updated the drivers to fix the problem
