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!

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

I HIGHLY RECOMMEND THIS.

are you a big fan of the old mx518? well then you are going to love the new G400! but this time with up 1000hz polling rate for smoother gaming!
i love it!

I've used a Logitech MX-518 for many years. I love my mouse, but it's beginning to show it's age a bit. When I saw that the G400 was being touted as the "replacement and upgrade" for the MX-518, I knew I just had to give it a shot. Sadly, I was disappointed with the device overall.

The good: The speed of response of this mouse is amazing! So much so that it really takes getting used to. As the resolution of the sensor is incredible. Have a dual monitor setup? Mouse from one side to the other quickly and comfortably. This part of the mouse is really amazing.

The bad: One thing I really loved about the MX-518 was the feel. The two mice share the same size and shaped. They even have the same buttons. But the G400 feels cheap. There is no weight to the mouse, and the plastic feels cheap in your hand. The MX-518 has some heft to it, the case of the mouse was smooth and has a metal emblem. Going from the MX-518 to the G400 feels like going from a well-made family sedan to turbo-charged go cart. Sure, the go cart is faster and built for fun, but the family sedan is better made and more useful over all.

One last note: The cord on the MX-518 is about twice as big as the G400 (around, not long). The G400 cord looks and feels like if it has to make a sharp turn it is going to snap on you.

Overall: If you are a fan of the MX-518, this is probably not the "upgrade" or "replacement" for you. However, if you are looking for a high performance gaming mouse at a great price, give the G400 a shot.

After just a few months of normal use and no accidents, my G400 developed several mechanical problems. First, the right-click button began to be difficult to depress, and had a much louder click. Then, the mouse began losing connection intermittently, which I determined to be a loose connection between the mouse and its cable.

In my first email to Logitech support I don't believe they read more than 2 lines out of 10, so my followup was just two lines, and I managed to get an RMA. Good thing they have a 3 year warranty.

I can only agree with all the positives you've read elsewhere about the feel, response, and precision of the G400. But the poor durability and an unimpressive support e-mail response leave me unable to recommend this pointing device.

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: http://bit.ly/xp3lQy

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.

I really like the look and feel of this mouse. I've played a few games with it already, and it's nice having on-the-fly DPI switching. However, I have small hands, and this mouse is really hard to control when I'm accustomed to using my Microsoft 5000 Bluetooth mouse, which is very small. I've considered sending it back because of it, but I'm going to try to adjust to the size, instead of giving up on this great mouse.

Did a whole lot of research before I came to order the G400. As of this year Logitech has completely removed all angle snapping and acceleration on this mouse. What that means for you is that you will get a perfect 1 to 1 response. Very comfortable, nice software, excellent response.
All in all 5/5 for this mouse, very impressed.

At first I was afraid that it might be too big for my small hands, but it feels comfy and doesn't strain it at all. I was previously using a logitech m215. You can change the dpi "intervals" too just remember to download the program that goes along with it. The "reset to default dpi" button is pretty useless to me though. It might serve as a good push to talk button. I've played SWTOR with it, and it does have a notable feel change to it. There's definitely more precision to it. Overall, it's a great entry level gaming mouse for those who aren't ready to splurge a lot of money on a mouse. It is surely an upgrade from the mouse I was using before.

The Logitech Optical Gaming Mouse G400 is very comfortable to use, even for a small hand like mine. Your thumb fits perfectly into the groove on the left side of the mouse which gives a feeling of control. The two side buttons are located right above where your thumb rests so it is easy to find them and easy to press the right one.

When you aren't gaming the mouse doesn't feel as though it's bristling with buttons. The buttons are rounded so they don't dig into your hand. Some gaming mice are so full of features I for one get easily flummoxed as I can't think quickly enough to plug in the appropriate feature and these over-stocked mice just aren't feasible for everyday use whether or not you are gaming. The G400 is not as customizable as other gaming mice and may not be feature rich enough for professional gamers, but for most people it should be very adequate.

The DPI sensitivity is controlled by three buttons one above, two below the scroll wheel and the scroll wheel itself. Increasing and decreasing the sensitivity while you're playing, adjusting the sensitivity as you scroll 3600, 1800, 800 and 400 dpi is smooth and easy. This mouse is also the most smooth-sliding on the mouse pad I have ever had, it slides almost as though the bottom were waxed. Unless you wish a highly customizable mouse, the G400 is perfect for most people, gamers or not, who simply do not need a mouse with features that are often over-kill.
