On a side note, Logitech one-upped Amazon and has it for $52 with a coupon, but it's out of stock so you'll have to place your order now and wait for it to come back in stock later.
On your G5 question, it's a completely different feeling mouse so user experience may vary. It's made for both claw high sensitivity twitch gamers and palm low sensitivity players. IMO it's the best claw gaming mouse for twitch gaming, I have tried ALOT of different mice and the G9 has always stuck.
I've got a G9 and I personally am not a huge fan..
I like the claw grip shape and the texture/feel of the precision grip, but it's Laser vs. Optical and I'm just too used to my old 400 dpi optical mouse I think. The lift off distance is at least twice as much, and I just can't find a sensitivity/DPI setting that I like for most games (BF3, etc.)
Anyone else feel the same way? I'd love it if it had a high DPI optical engine instead with a lower lift off distance. I also feel the software is a bit too complex with the settings (for example, should I adjust DPI or adjust windows sensitivity? use setpoint drivers or windows drivers?, etc.) Add on top of that game specific settings (like BF3's "use raw mouse input" feature) and it's hard to know what the best settings are..
The macros, weight tuning system and switchable profiles are nice though!
As a side note, the G9 might possibly the only gaming grade mouse in existence that fits my hand (gripless, that is). Barring that, I'd have to resort to notebook mice. Kind of tempted to get a G9X for at home so I can use my old G9 at work. Also curious about the Saitek Cyborg R.A.T. series, and how small you can shrink one down to.
this mouse is just as responsive and accurate (at any acceleration rate) as my 1000hz overclocked mx300. i thought i would never find a mouse good enough to replace it...but then i tried a g9x
for reference, all i play are twitchy shooters. the dpi adjustment buttons took getting used to, but once configured properly, they actually come in handy. oh, and you know wat fixes the braided cord wearing problem? electrical tape.
I was given this as a birthday gift and i'm not a huge fan. I have an alienware one that's almost identical but doesn't feel cheap like the logitch does. I find both of the logitechs detachable grips uncomfortable.
My G5 died in a fit of rage at a LAN a month or so ago and I would take it over the G9x any day.
Edit: I'm a palm user not a claw user if that helps anyone. The mouse does feel very comfortable if I use a claw "stance".
