The customisation of the mouse doesn’t stop there. It is also possible to equip the mouse with little weights, for those who find the standard weight (126 grams) insufficient. The loading of the weights is done by inserting them into a drawer on the right side of the mouse. You can put in up to three of the four weights supplied (three 10g weights and one 5g one). For our tests we decided to stick with the original weight. Thankfully it’s pretty bad-ass looking and so doesn’t give off the idea that it’s a toy when you’re slotting in the pieces…

The mouse also comes with two additional sets of its five skates, one of which one is made of Teflon which gives the mouse a nice glide. We can’t see a reason not to use it generally except to avoid wear and tear. Best save it for special occasions. The box containing the weights and additional skates is made of anti-slipping rubber and has slits where the mouse cable can be inserted. When you close it it serves as a convenient cable-guide. The set of the mouse’s functions is handled by the classic IntelliPoint, with the addition of a tab to manage the sensitivity feature. It also contains a macro setting feature to allow you to assign shortcuts to different combinations of mouse clicks.

The aforementioned feature is activated by a dedicated button on the mouse. We will come back to it a little later before the test. It is also possible to set the macros, quite effectively, in a dedicated macro editor before assigning them to the button of your choice. This feature is implemented quite well, for the most part. Our only complaint is with the management of different profiles and the assignment of macros. You’re going to have to assign commands one at a time, rather than being able to modify a set of them concurrently.

The G9 really stands out from its Logitech brethren: It is more sensibly shaped and bigger than the Side Winder and has of a laser sensor with superior sensitivity of 3200dpi, versus the Side Winder’s 2000dpi. Logitech have really outdone themselves with sensitivity, which is much higher than its usual standards.
