Logitech G400sOptical Gaming Mouse

Bought this mouse primarily because I wanted to have a couple extra buttons available when playing computer games. I did my research, settled on the G400s and have been happy with it for 9 months running now. While it is marketed as an FPS gaming mouse, this is an easy recommend for anyone based on excellent ergonomics, customization and durability in particular.Pros:Durability - Buttons rated at 20 million clicks. At my present rate of use this mouse would last another 50+ years. There are no signs of mechanical wear whatsoever. The only hint that the mouse is used at this point is a slight bit of abrasion on the pearl-colored "G" logo on the mouse.Ergonomics - Deep thumb groove means mouse is secure in hand and easy to pick up. Fits natural curve of hand with good button placement and feel.Sensor Accuracy- one of the most accurate sensors on the market. This likely won't matter to you unless you happen to be a fairly hardcore gamer but is a nice bonus for any user.Software- The mouse is plug and play and the forward/backward buttons are usable out of the box, but the buttons near the scroll wheel need the Logitech software to be mapped. The Logitech software is slick, light, powerful and quick to install and use. Be it a game or Microsoft Excel, there is no reason productivity doesn't go up relative to a standard mouse.On the Fence:Styling- This is a souped-up premium office mouse with gaming innards and a new paint job. The styling will be hit or miss with most. The office types won't like the gaming paint job and the gamers won't like the fact there are no flashy LEDs. To both I say, "function over form."Cost- You can get all the office functions of this mouse for $30 if you need the buttons but not the "Zero Delta" sensor or 1000hz polling rate etc. As a gaming mouse, it is well-priced compared to its main competition.Textures- The mouse comes with "hydrophobic surfaces" which are durable and resist sweaty palms. They work as advertised and are very durable but many people don't care for the "all plastic" feel of the mouse. The mouse works and it works well. If you need a rubber or satin feel to your mouse, seek therapy immediately and spring for a different (likely inferior) mouse in the meantime.Cons:Lack of braided cord- this could/should be standard these days. Braided is better for looks, sounds (nobody wants a mouse cord that goes fwap fwap all day) and generally staying out of the way.Scroll Wheel- No issues personally, but the profile is admittedly low, it is simply a smooth rubber wheel with a little bit of cheap wiggle and it appears identical to what is on Logitech's $5-10 mice. For a $50 product, it seems rather out of place. That said, it works and this is a rather nit-picky con some wouldn't even notice were it not for the gripes of others.In summary: impressed overall, particularly with the durability aspect of this mouse. 9 months in and I am beginning to believe it will outlast the USB port concept...

I love this mouse. It's a throwback to the very first gaming mouse I'd ever owned when I was 12, and it's a faithful reproduction with just the right amount of improvement.Some gaming mice on the market look as if they have been designed in a laboratory for non-human hands. They'll allow you to change the weight, shape, size - everything. To me, this is just another distraction to prevent you from being completely focused on the game, and I place more value in the consistency that a static configuration provides.The shape of this mouse is as close to perfect as it gets. It's not too ridiculous, but provides enough contour and comfort for accurate gameplay for hours on end. The weight of the mouse is great, and the button configuration is true to the original; the ability to change DPI on the fly is critical to my gaming and web browsing experience. It is coated with a material that provides a good amount of grip without giving the mouse a rubbery feel, and the feet slide very well over my aluminium mouse pad.Overall, I would highly recommend this reboot of a classic mouse to anyone that is serious about gaming. The other mice on the market seem a bit gimmicky when it comes to shapes, configurations, and personalization options. This is about as advanced as a mouse needs to be, with just the right amount of buttons, and a contour that fits your hand well but isn't overbearing.

Well, let's get to a point quickly. I have a Logitech MX518 that's been in used for nearly 4 years and at times it flashed on and off from active to dead---as in no connection,-- until I figured out that the setting were too high, too fast, for use as a plain vanilla web page mouse application. Seems that the mouse response time can be quite faster than an actual internet connection, especially when using public Wi-Fi system that lag or bogs down in processing speed. So I tuned the response feature down a bit, scrolling went from 8 lines per click down to 3 lines and the refresh Nano-seconds time stayed up with the mouse commands rather then go into suspension or freeze out.I figured out that this works just as well using the G400s. My laptop,equipped with an Intel processor, is very quick, the G400s also has a very accurate and quick response, but an actual internet/Wi-Fi lags a bit due to overloads, weak signal or weather conditions, point is the slow or lack of response often experienced is not a instrument (mouse) issue --as some folks like to downgrade this products genuine top quality response and accuracy.,,,,, I do like the MX518 finish better than the G400s, but both are super fine, durable and fancy color coated finishes as well as both just seem to truly fit my hand better than any others I have used, (smaller footprint),,, one disappoint is that the G400s has a "stiffer-wire/cable and much small diameter than the MX518 unit (which is thicker and does not get caught or stuck with movement against other equipment edges and corners --its also much more flexible). Having the correct software version from Logitech updates site tweaked out 98% of "no response, slow response issues,, don't rely on MS or Windows updates , it from the Logitech folks.

Bought in 2014, used from 2020-2025 ~60 hours a week and from 2014-2020 probably 20 hours a week. All that use and it finally died in June 2025, over 11 years and ~20,000 hours of mixed use. Now the challenge of finding a replacement.
