We might as well be honest; the G7 is a great mouse.  In terms of innovations, there is now a more precise laser sensor instead of an LED, a significant increase in resolution as we now attain 2000 dpi, on the fly resolution adjustment, and a system of interchangeable batteries (see box).

First of all, the G7 is a 2000 dpi mouse.  At its maximum resolution when you move it 2 cm to the right, the cursor travels 1600 pixels in a single bound or in other words an entire 20 inch LCD.  This is fast!  Luckily, Logitech equipped its product with two buttons to instantly change the resolution.  By default there are three levels: 2000, 800 and 400 dpi. You can easily add two others and even modify the existing settings with the accompanying driver.  On top of the mouse the current resolution is displayed via an orange indicator (green is the battery level).  The higher the level, the faster the cursor moves.  The adjustment is done instantly and without delay.  This is as practical in games as it is in Photoshop, or to quickly cross a dual screen configuration.


Even if you master a 1600 dpi mouse like we do, 2000 dpi isn’t that easy.  You will need a very large screen (23 inches or larger) to make good use of it, and even then a dual screen 23 inch system is preferable.

As for its design, this G7 has inherited a large part of the MX518’s chassis. Compared to the MX1000, Logitech’s other laser model, this is a low and light mouse and for this reason better adapted for fast games.   However, this means it is less "comfortable".  Those who have to have the latest mouse and abandon their MX1000 for the G7 will gain slightly in reactivity, new curser speeds (the MX1000 is limited to 800 cpi) but they will also lose a few buttons. For example, there is still the one under the thumb to go  « back » in navigation, however, the « forward » button has disappeared.  Also gone is the MX518’s button allowing navigation between applications.  On the other hand, the scroll wheel is now laterally moveable and contrary the last Apple Mighty Mouse, it functions as well on a PC as it does a Mac.

Underneath the mouse, the foot covers are much larger than what we usually find for Logitech or even Microsoft.   In our tests, this mouse was new and it glided wonderfully.  We hope this is prolonged due to the larger foot surface, however, only time will tell.
Finally, this product was released at the same time as another similar cabled version, the G5.  The latter is a bit less expensive and offers a new and innovating adjustable weighting system of 1.7g or 4.5g weights.  Up to eight of these can used in any combination.
