Weights, Wheel and Buttons
The new weights are sort of square in shape and come in 4 and 7g weights. It means that you can load more weight in total than the G5, but you don't have the same kind of fine tuning. It's easier to insert and remove the weights into the cartridge this time around, as the new weights don't have the rubber grommets like the ones with the G5.
The weights are stored in a similar looking metal box as the one that came with the G5, but it does of course say G9 on it instead and it's been made to fit the new weights. We have to say that Logitech missed a trick here that Microsoft picked up with its new Sidewinder mouse and that's the ability to use the cartridge case to keep the mouse cord in place.
The scroll wheel for the G9 is taken straight from the VX Revolution. Why the VX and not the MX you might wonder? Well, it's simply because the MX uses an auto switching wheel while on the VX you have to manually switch between the modes. The G9 has a button for this on the bottom, just like the VX Revolution and it's not exactly what we'd call clever. Having to flip the mouse over all the time gets kind of annoying.
None the less, the MicroGear scroll wheel is a great addition for those that want to use their mouse for more than just games. However, we have a couple of minor complaints. The wheel itself isn't the same as for the Revolution mice, it's either made from aluminium or plastic instead of that nice heavy solid metal feel that you have in the Revolution series. For some reason Logitech also made it a lot smaller and we can't quite figure out why this is the case.
Otherwise it feels much better than the older scroll wheels, although it's quite stiff to press down and for anyone that's used to using the scroll wheel as a reloading button in games, they might want to use a different button on the mouse for this. The two main buttons are quite long and sort of half pipe shaped, which is also quite different from the G5 series which had quite flat buttons.
They are actually quite comfortable to use, even for longer periods of gaming and they work well with the design of the grips. Some people have complained about the location of the dpi adjustment switch, which is just above the left mouse button. However, it's actually quite easy to use once you figure out that you can press it with the rear part of the top of your finger by moving it back just slightly. It's hard to explain exactly how to do this, but once you get to hold a G9 you'll know what we mean.
The last button on the mouse is found at the bottom again and it's for selecting one of the three profiles you can store onboard the mouse. You press the button and then use the dpi setting button to select the profile you want to use.
