Introducing the Logitech Optical Gaming Mouse G400

Today I’m excited to announce the launch of our latest gaming mouse, the Logitech Optical Gaming Mouse G400. It is the successor to the MX518, our best-selling gaming mouse ever.

When we started working on the G400, we had only one goal in mind – to take everything that was right with the MX518 and make it even better.  We were very careful not to mess with the shape, tracking consistency, button layout, or legendary durability that millions of customers have grown to love and rely upon over the years – we even kept the suggested retail price the same.  All we wanted to do was make a legendary FPS gaming mouse work even better.

To accomplish this, we started by upgrading the 1800 DPI sensor to a higher-resolution 3600 DPI version.  This makes it possible to accomplish high-speed turns without wide hand sweeps or losing fidelity by turning up cursor speed in the Windows control panel.  DPI levels are still adjustable on the fly (to 400, 800, 1800, and now 3600 DPI) with no software required.  And since we’re using an upgraded version of the MX518 sensor, you still get the same tracking consistency (<0.5% cursor to hand movement variance at up to 140 IPS, depending on surface) you’ve come to expect from the current product.

Next, we increased the report rate from 125 to 1000 reports per second.  This is as fast as USB can communicate, and it means that all movement and button clicks are interpreted by the computer as close to real-time as is possible – so there’s never any lag between your hand movements and what you’re seeing on the screen.  And to help you move the mouse more easily, we also changed the USB cable – making it thinner and 25% lighter.

The last major change is to the optional button programming software.  Even though the mouse works great out of the box with no software whatsoever, we know that many of our users like the extra edge our button and tracking configuration capabilities can give them.  That’s why we’ve integrated the G400 into the same software used to program the G-Series keyboards and the Logitech G13 Advanced Gameboard – so you can create a macro once and use it on either your G-Series keyboard or your G400 Mouse.  This change gives G400 users access to Logitech Gaming Software’s easy-to-use drag and drop interface, as well as its robust automatic game detection, macro, and scripting capabilities.  Logitech Gaming Software v8.0 includes profiles for 210 games, and creating new profiles for games that aren’t on our list is quick and easy.

The Logitech Optical Gaming Mouse G400 will retail for $49.99 and will be available in the US at Best Buy beginning June 19, elsewhere in the US in early to mid July, and in the rest of the world beginning in mid-July.   For more information, please visit the product page.  And feel free to let us know what you think in the comments section.

  • I’ve been waiting AGES for a good mx518 replacement, and I was happy that you announced it. But then I read the comment about angle snapping, so there will be NEVER a chance to disable it? The angle snapping was always a big minus on the mx518.

  • Yeah, the angel snap is a deal breaker, otherwise perfect mouse.. : S except for a thrid button instead of scroll ofc.. but that will never happen : [
    and a little bit higer arch, with the tip further back.. : ]

    • Hi dvnt,

      It is at Best Buy exclusively from June 19 (may not be at all stores immediately) and everywhere else in early to mid July.


  • With a Logitech Illuminated Keyboard, will I have to use two software-suites simultaneously? (Setpoint + Gaming Software)

    I’d rather have one of them recognize both of them. Having a single application recognize all Logitech hardware, saves the consumer the worry, when contemplating a new purchase. Currently I have a G5 and the Logitech Illumated Keyboard. Both are recognized by Setpoint.

    As a seperate note, I really like the visual design of the new mouse. I’ve never understood the fascination with shiny orange, blue, rust etc. I’m no 1337-gamer, but I still want the hi-tech stuff, just in a stylish package (think MAC, B&O and the likes, not generation X Extreme ROFLMAO gaming styling).

    • Hi Thomas,

      SetPoint will not recognize the G400. In the past, our mice have not been recognized by our gaming software, which was an issue for customers who owned our gaming keyboards. This is why we migrated the G400 to the gaming software. At this point we do not have any software that recognizes every single device we manufacture.

      Thanks for your comments on the color scheme – I feel the same way. ;)


  • Hey, so it’s June 20th, and I pre-ordered the G400 on June 10th. Does that mean it will be shipping out this week?

  • So its june 20, when will this be released? I called logitech customer support and they didn’t know either

    • Hi paul,

      I do not have a specific date available. The best I can offer is early July.


  • Is there a wireless version coming out as well? I love my old g7 and I would like to see another rechargeable mouse that looks like this new one.

    • Hi,

      Whether we are working on a product or not, it is our policy not to discuss products that do not have an official launch announcement.


  • Hi Chris,

    It still says “pre order” on the Logitech website. Is the G400 shipping in the U.S. yet?



  • Hello, has the G400 started shipping yet? I’ve checked the product page and it is still listed as a preorder. Also, when will it be widely available at retailers such as Amazon and NewEgg? I’m extremely interested in this mouse as it addresses my only gripe with the MX518 which is the glossy surface. I’m currently using the G500 and the non-glossy surface is a lot better at preventing a dirty build-up but the shape, sensor, weight, build quality and feel just isn’t as good as the MX518 in my opinion. I’ll be on the look-out for reviews. Thanks for the info though.

  • I went to Best Buy in Jacksonville, FL last night and they do not have this mouse in stock?

    • Hi Kenneth,

      Not every store will immediately have the product in stock. They have been available starting from June 19, though. It will take some time for the product to make its way through the distribution channel.


    • Hi Sam,

      The scroll wheel has the same ratcheting profile as the MX518. It is not a free-spinning wheel.


  • i was using an mx518 for 5 years and i decided to buy a G500 and im happy with it but i would like to know whats the diff between G400 and G500 (except from the lazer vs optical)

    kind regards

    • Hi head,

      The G500 is a higher-end product than the G400. It has a 5700 DPI laser sensor, three buttons on the thumb, two extra buttons on the index finger area, the HyperFast scroll wheel that can switch between ratcheted and free-spinning modes, a braided cable, and weight tuning capability.


  • Aw, I know there’s a massive market for this level of product, but I’ve been waiting ages to get a new high-end mouse (I currently have a G5 but want something with more controls!).

    So I’m waiting for either a wired version of the G700 (great mouse) – or maybe a completely new design (with lots of buttons/controls), definitely wired.

    • Hi NightCabbage,

      Thanks for your feedback. We’ll take it into account as we develop future products.


  • Hi Chris,
    nice to see that you give an answer to every question :-)
    Here is mine:
    Why should I wait for the G400 instead of the G500?
    I really tried to find a reasson becouse i prefer the design. But their arn’t any technical innovations, are their? Even the dpi is lower. So i would say it must be cheaper (would be defintly a reason) but it isnt the g500 is now about 2 years old (not sure) and so the prize is down to 41,80€ compare to the G400 with 41,40€ (expected).
    So I’m bit of confused… and will not belive that a 2 year old mouse is as good as a 07/2011 released one.
    So it would be nice if can tell me technical details which are not on the website or at last help me by recommend one (by reason^^)



    • Hi manuel,

      While the G400 is an excellent mouse and performs incredibly well for all types of games, it is absolutely not intended to be a replacement for the G500. Its feature set, as I detailed in an earlier response, is not as robust as the G500′s. This is why the recommended retail pricing for G400 is €44,99 while the recommended retail pricing for G500 is €69,99. What retailers choose to actually charge for the product is their decision, and we do not have any control over it.

  • Well done!

    I also have a question for you Chris.
    I think you forgot to mention this in the spec- part. It’s the lift distance of the mouse. I’m the type that hates if the mouse tracks when you lift it, so this is very important to me.

    Thanks in advance, and again good job.

    • Hi James,

      We do not list an official liftoff distance for the G400, but it should be the same as what you would find on the MX518.


  • Hi Chris,

    Just wondering: how long is the cable? I couldn’t find a mention of it in the specs.

    Thanks in advance!

  • I am currently using an early version of the MX518, bought in May 2005 (Sweden). Does my version have angle snapping, and can I expect the G400 to have a fundamentally similar behavior to my mouse even though it is such an early revision?

    • Hi John,

      The angle snapping behavior is identical to the MX518. You would notice no difference in that regard.


  • Hello Chris,

    I am a big fan of gaming stuff in general and already spent a decent amount of money in Logitech products (keyboards and mice).

    Being a proud owner of a good old Mx518 (among so many others), I got pretty excited about knowing it would get a successor.

    I still wonder what made you change your mind regarding the aspect of the mouse since Logitech always chose to have particuar look (not always the prettiest in my opinion tbh) like the Mx518 / G5 vs1 / G5vs2 / G500 etc…

    The G400 kinda reminds me the Steelseries Xai / Kinzu, and according to me you’ve just gone from an extreme design to another (crazy looks –> as simple as possible). Aren’t you afraid of loosing some customers due to the fact that the first impression may not seduce the gamers that liked something that “strucks”?

    Would also suggest you to think about an MMO mouse that would FIT a common hand?
    I play a lot of MMOs and the more buttons a mouse has the better, but the great majority of the MMO mice out there do all have serious drawbacks:

    - Steelseries WoW mouse: too big (both of them)
    - Razer Naga: weird layout, very hard to get used to and not misclick the buttons 1 to 12
    - Logitech G700: too heavy, when wired the cable tends to keep the mouse in it’s alignment, doen’t try to create an MMO mouse and replace the Mx1100 at the same time… and still the best out of these 3!

    You can reach perfection, just follow my advice :) (kidding)

    Gonna buy the G400 within the nexts weeks of course, need to complete my collection.

    thanks a lot for feeding my passion,

    Best regards.


    • Hi Pedro,

      Thanks for your detailed comments. The paint color decision was made after reviewing a significant amount of feedback from existing customers as well as people who did not purchase a Logitech G-Series mouse. We are always trying to make sure our products match the tastes of our customers, and the paint scheme on the G400 reflects that.

      Your suggestions and insights into our gaming mice are greatly appreciated. We aren’t at liberty to discuss our plans for future products but feedback like this always plays into our design decisions.


  • Hello,

    this mouse looks very promising to me. But one question is itching me.

    Does negative or positive acceleration occur at high moving speed.

    • Hi koR,

      There is less than 0.5% variance in cursor movement vs sensor movement distance at any hand speed – same as the MX518. This means there is no perceptible negative or positive acceleration.


  • Does G400 automatically set itself to the 1000hz or do you need to change it via software comign with it?

  • Could you please tell me if this mouse has more or of a percentage of less error correction angle & snapping compared to the newer 518?

    Is it possible to disable this or could you add a driver update to alllow for an option to turn it off?

    I’ve only ever used logitech mice and I will stay with this g400 but I would like this option.

    • Hi James,

      The G400 tracks identically to the MX518. There is no way to disable the G400′s angle snapping feature via software, so there can be no software update that enables such functionality.


  • Hello, I was wondering if it would be better to buy the G400 or G500, seeing as the “As fast as a mice can go on USB”.. Is this the same on G500? Wich options does the G400 has more then the G500 and visa versa?

    • Hi Timothy,

      The G500 is a higher-end mouse than the G400 and has a few more features than those found on the G400. For example, the G500 features our dual-mode scroll wheel with horizontal scrolling capability, weight tuning, and two more programmable buttons than the G400. The G400 uses an optical sensor as opposed to the G500′s laser sensor, and it weighs less than the G500 as well. Both mice can communicate over USB at up to 1000 reports per second, and both have a similar shape. So really it comes down to your personal preference – both the G400 and the G500 are excellent mice for any type of game you’d want to play.


  • Looks to be a very solid release. Going to try this out over my G500. Optical with 1000hz poling rate out of the box!

    My G400 is on the way! Will post back :)

  • The time has come to change my very old MX 510 (which has served me and still is from 2003 or 2004). Will the G400 feel pretty much the same to me ? And could you explain the “angle snapping” thing…not familiar with this…will it affect the mouse behaviour much?

    • Hi Sarge,

      The MX510 has angle snapping as well – though to a somewhat smaller degree than the G400 or MX518. In practical terms, your gameplay experience should be pretty much the same at the same DPI.


  • This is great news. I’ve had the MX518 since it came, and it still performs like it did then. I’ve considered buying more of it to be sure to have it even when it goes off sale, but now I don’t have to.

    But I have a driver problem with the MX518, and I’ve had it since the beginning, on all my PCs since then, so not just one Windows installations problem, or one set of hardware etc..

    I’ve always used the buttons that are just above and below the wheel to scroll, I don’t change the DPI on it while in use, or ever, but sometimes in Windows when I click the buttons to scroll, it changes DPI instead, this is driving me nuts. Is the G400 the same or is this fixed?

    Yes, I have the newest drivers, and it’s never been fixed, it’s been like this since it first was available.

    I might be buying the G400 soon =)

    • Hi Alexander,

      I have only done limited testing of this personally, and I had not heard of it before you brought it up just now, but from what I can tell from my testing and what I know about how the software works it should work properly. If it does not, then that is an issue we need to correct in a future build of the software because the buttons should only do what you program them to do.


    • Hi Alexander,

      I was out of the office at the PAX Prime game show and just got time to get back into approving and replying to comments today. Sorry for the delay.


  • Will Logitech release a firmware update for the G400 to disable angle snapping?
    Is Logitech working on the jitter issue of the G400 when the software is installed? Many people have reported the mouse skips pixels/”jitters” when the Logitech Gaming Software is installed and this is a shame because some people need to program the buttons on the mouse to their preference. Otherwise a great mouse, color and design. Thanx.

    • Hi Jose,

      It is not possible to update the G400′s firmware over USB, so there will be no firmware update posted.

      We have identified the root cause of the cursor behavior you are describing and there will be a software update in the near future that will make the G400 track with the software running the same way it tracks without the software running.
