    Great mouse and very responsive.
    This Logitech mouse is for me the successor of the MX518 from Logitech, the best mouse ever.
    I would highly recommend this mouse as a sensibly priced option for a gaming mouse.

    Vine Customer Review of Free Product ( What's this? )
    I replaced my trusty old MX518 with the new G400. The G400 took zero getting used to because it's the same identical body as the MX518. All the buttons are in the same places, and the outer shell is exactly the same as the MX518, except for the "gun metal" texture of the 518. The G400 has a nice dark gray texture.

    The scroll wheel is a lot quieter than the MX518 (no clicking sound, super silent unless you scroll really really fast) but still has the precision "click" feel to it that gamers prefer. As with the MX518, the G400 can switch DPI on the fly, but the other buttons won't do much out of the box unless you download the software from Logitech's website (there is no included CD). They can be programmed by application without downloading the software. I use one of the thumb buttons as a "push to talk" in Ventrilo, and I did not even have to reprogram it when I switched out my old MX518.

    Some specs at a glance:
    + 400-3600 DPI
    + 5.8 megapixels per second tracking
    + 1 millisecond USB report rate
    + 133g total weight
    + lightweight 15g cord
    + 10 million-click button life
    + 250km feet life

    The big difference over the MX518 is the 3600 DPI precision--twice that of the MX518--and 1ms response. I've always been a fan on the MX518, and this upgrade to the G400 is very nice, and very affordable. I love it!

    Don't you hate reading an Essay format product review to extract key points that can be written in less than a few sentences? I SURE AS HELL DO.
    --My Credibility: I have competed in gaming leagues playing Counter-Strike back in the day.
    --I have tried out the Logitech G500 & G700 before settling for the G400. Both mice are a little larger and have unnecessary buttons that is not practical. (who the hell needs 10 buttons on a mouse! Incorporate your keyboard! that's the point of your left hand.)

    The G400 is the direct successor of the MX518, which is regarded as a legendary mouse among the community. I still use my MX518 at work and its going strong for 6+ years already. The G400 version is actually 10-20% lighter than the MX518.

    Who cares about over 900000000 DPI. All the Pro Gamers (even today in Korea) still use basic 2 button mice to game competitively.

    Optical vs Laser? The only person who should worry about this is the person who uses their mouse on a glass table, but really who the hell would do that anyways?

    "Gaming" mouse vs "Non-gaming" mouse: This is marketing. Buy a mouse based on how it FEELS after extended use and not what others say or how much reviews it has. Don't pay attention to specs. Its the player that wins the game, not the mouse!

    -Solid Build
    -Lighter than MX518
    -Looks good
    -Works out of the box (no CD package or install required)

    I purchased three of these Logitech G400s for use by three different people on three different systems and all three were experiencing random drop-outs within three to four months of use. These G400s are not "disconnecting" like my four or five year old MX-518 with cable problems, but instead they simply seem to randomly freeze up for 20 or 30 seconds at a time. I'm very dissappointed with the G400 as compared to my old MX-518. Even before the random failures, I had noted some mouse pointer jitter and even occasional run-away with the mouse seemingly sitting still. Never had such problems with the MX-518. Hey, Logitech, dump this POS and bring back the MX-518!

    If you loved your previous Logitech MX-518, I'm afraid you're likely to be sorely disappointed with this supposed successor, the Logitech G400.

    Despite having to install special drivers, this mouse was decent for about a year. Then it began cutting in and out intermittently. I thought I had a lemon, so I contacted Logitech support. They weren't interested in fixing it, despite going back and forth with me with silly 'reinstall driver' fixes. Oh well.

    Then I Googled the issue. Turns out TONS of folks with G400s get the same intermittent cut out issues after a year. This is clearly a known issue, and since Logitech is ignoring it, I'm never going to buy another Logitech product again. I paid premium for a mouse that I thought would last more than a year... for the price, this is definitely not worth one years worth of use.

    Edit: Angle snapping(prediction, drift control) has been removed on the G400. Product ID(PID) starting with 13333 and higher have angle snapping removed. Official source: [...]

    The G400 at the current price of $31.99 shipped is a best buy in my opinion. Couple it with the SteelSeries QcK mouse pad at $9.99 shipped, and you will have a wonderful combination for gaming or general computing.

    My hand is 7.5 inches from tip of middle finger to wrist. I can use the mouse in the palm grip or claw grip. Both grips are very comfortable to me. The right and left click is good as it gets, and the Omron switches are rated at 10 million clicks.

    I had to modify the grip on the right front side of the mouse because there is a thin hard ridge of rubber that protrudes, and it irritates my ring finger when it is hanging off of it. The G400 mouse grip is designed for one to keep three fingers on the mouse click area. I left click with my forefinger and right click with my middle finger, and my ring finger usually just hangs off the side of the mouse, or I have it against the side of the mouse for grip.

    The thin hard ridge of rubber at the front right side of the mouse had to go, so I used a dremel with sanding drum and sanded it off. Then I took an emery board and sanded it smooth. Now I can use it with three fingers on the mouse click area, or let my ring finger dangle off the side of it, or use my ring finger to actually grip the side along with my pinky finger.

    From what I read, the G500 does not have the rubber ridge on its grip. The G500 costs over twice as much as the G400, so modifying the grip of the G400 was dollar wise in my situation.
