The G9 is an impressive mouse, the features are solid enough, it also sends a signal for me that it's about time to retire the MX518 as in most of the tests I couldn't find a reason to really mention it, often was it that it played up in enjoy ability with the G5 but the responsive nature of the G5 left it in the dust, or that if it was flowing better than the G5 the Deathadder smashed it. The 518 is a good unit still, but it seems that the times have caught up with it in these newer shootout cases.
Looking past that, the G9 offers some things that make it worthwhile, the interchangeable grip is nice, it feels comfortable when things are really heating up, it works to the job it's designed for and keeps me in the middle of the battle and things like the MicroGear just melt me away, there's something about blistering speed scrolling that is really amazing to have. The DPI range is amazing and gaming at 3200DPI is something else for sure when I thought I had really seen it all with previous laser mice at the 2000 level. There is a level of precision in action but for the passive player, who doubles into things like Photoshop, 3200 is probably going to be one of those moments that seem overkill as the mouse speeds around, thankfully scaling back can fix that issue though.
With the G9 coming in around the $60 - $70 mark it is a hard sell to make; will those holding onto their G5 want to make the jump? for the passive gamer it will probably not. Will it be enough though for the enthusiast though? It's probably a really good consideration because of the shift that the extra speed makes in game right away.

Out of the field of gaming products I had to use, the G9 was the outsider, it didn't have the looks and it seemed rough on the edges, after trial and testing though, the mouse works and it lives up to the category of gaming mouse because really at times it decimated what I could do on my other devices, the speed is intense to experience right off the bat and generally needs a warm up period but after it hits that sweet spot, the mouse just hums along as bodies fly and bullets fill the landscape as I click along. I can be picky and say I'd love to make some custom macro calls for it beyond KB/Mouse recording but it's not bothering me that much because it's more of an ideal feature more than anything else.

For those out there ready to retire their basic mouse or even older gaming mouse, I'd really give some thought into the G9, it's a powerful mouse with a lot of options, the weight system, the grip changes and the profiles make it attractive for all types of gamers especially those on the go or with multiple configurations. If you see it in person, try to play with it, check out the shell the loader system, the MicroGear on or off and just the general feel of the mouse, it's a bit of a change from the normal gaming devices.
The Logitech G9 was one of the few mice I wasn't sure about, but through trial and testing and abuse the mouse held up strong and has earned a full time testing seat here until a new challenger emerges.
