One immediatelly notices the high dpi rating. For example inside the Microsoft Habu and the Logitech G5 is a 2000 dpi engine. 3200 is a noticable increase over the old "gaming standard". Movement of the mouse is reported to the computer via USB port 1000 times a second. There is no sleep mode so you know that your game character will move when you tell it to move and not couple of milliseconds later. Gotta love that when lead, plasma etc. starts to fly towards you.

The thing I love about Logitech's recent mice is the MicroGear Scroll wheel. In games, it is nice to have stepped rotation of the wheel so one can make precise selections during the battle. When surfing the web, I prefer the frictionless scrolling. It is great to see this scroll wheel included in the G9 too.

In this image one can also see the sensitivity adjustment buttons. Logitech decided to place them just behind the left mouse button and while the position seems great, the buttons feel bit hard to hit during intense gaming. Perhaps if they had something, for example a small rised dot on top of them, they would be easier to locate. Just a thought.



Here we have the polytetrafluoroethylene feet. Good amounts of gliding surface and the large area also stabilizes the mouse. MicroGear button is used to select the frictionless or stepped scrolling of the wheel. Profile button is used to select the wanted profile from inside the built-in memory of the G9. This feature allows one to take their gaming and program profiles with them and use them on some other computer without installing the Logitech software.

I would have liked to see both of these buttons located on more convenient location. They are not used that ofter but bottom of the mouse just seems as a last place where these buttons should have been placed.

At the very back of the mouse is a button that is used to operate the machanism that releases the grip. "The Grip" you ask? Read on to find out.




Logitech provides two interchangeable grips with the G9 mouse. Wide Load Grip is intented to be used when user wants fuller shape and wider thumb rest. This could be thought as the productivity grip from these two.

Precision grip is slimmer, thus making your grip from the mouse feel different. With this, you use mainly your fingers to control the mouse as with the Wide Load Grip you would use your hand/palm.

Both grips have different surface finishes. Wide Load has a satin, bit like rubbery surface. Precision Grip has what is called the DryGrip Technology. Call it what you want but basically the surface feels bit rough and hard. In the future, users can buy replacement grips from Logitech that have widely different shapes and surface finishes. Perhaps we might see some 3rd party grips as well.

Is it just me or does the G9 in the middle seem bit naked?!



Microsoft Habu introduced the changeable side button placements. In G9 the button placement stays the same even when one changes the grip. This is the case with these two bundled ones but I believe we will see bit more variation in the upcoming grips. At least I hope so as there are so many users that will find the default button placement restricting.
