Features:
The exterior of the G7 mouse is a dark green colour and if seen in the right light there is a slight sparkle finish to it. The top of the mouse is a silver colour, this starts from about the heel of the mouse and goes up to the the end of the buttons. The buttons themselves are much like the MX610 we looked at a few months ago, that is, they are both a part of the top piece of the mouse with no cuts at the back like older style mice. You can refer to the picture below for a better understanding of exactly how they look.

In between the right and left buttons is the scroll wheel and two small round buttons labelled "+" and "-". First I'll talk about the scrollwheel; it is capable of both vertical and horizontal scrolling much like manufacturers are starting to do on all new mice. The plus and minus buttons are the real magic of the G7 mouse. They allow you to change the resolution on the go! You can chose from 400dpi, 800dpi or an amazing 2000dpi! It is easy to tell what resolution you are in because there is a small set of LED's on the left side of the top of the mouse. The very top LED is a little picture of a guy running, that tells you the LED's are currently displaying sensitivity. The other three are little squares, the one closest to the man being the full 2000dpi mode and the bottom being 400dpi. If the mouse is stationary long enough, these LED's will fade from the red colour into a green colour and the man will no longer be lit at the top, but a small green battery will light up at the bottom. This is now the battery mode and your batteries charge will be shown with the 3 green squares, all 3 being fully charged of course.

There is only one button on the left side of the mouse for your thumb, this is simply a back button. I really wish that Logitech would use the back/forward button combination like we saw on the MX610 as having both is a lot more useful.
