Pros: Sturdy, great texture, good mouse clicks, DPI quick changing buttons and instant reset work as advertised. Comfortable to hold. Scroll wheel has a nice tactile click to it. Software very easy to use & configure mouse with.
Cons: No tilt-wheel. Little lighter than I prefer. It's sturdy and doesn't feel cheap, but I just like a heftier mouse. I don't game for 8 hours straight, so maybe I'd change my mind if I did. Not sure the paint job will last a few years with my rough man hands constantly rubbing on them.
Overall Review: I'm not a super avid gamer, but I have developed a tendency as I've gotten older to prefer purchasing higher-quality and a bit costlier equipment since I can now afford to. This goes for my home equipment and also my work equipment. I tend to purchase gaming equipment because it's usually engineered well and can take a beating. My old Razer Deathadder Black 3500 High Precision 3.5G Infrared Gaming Mouse died after two years, and I've never had a mouse ever die on me after maybe 20 years of working and playing with computers. So, decided to skip replacing it with another Razer and instead try out a Logitech gaming mouse. Glad I did! I'd recommend this and would buy it again.
Pros: Uses same A3095 sensor as late model g400 mice. Best verifiable optical sensor for a mouse I can find in my research. This includes the higher end gXXXs series mice which use a different sensor. No positive or negative acceleration, prediction, skipping, z axis issues, or angle snapping.
You point and it goes exactly where you tell it. (Shouldn't all mice be this way?)
For my larger hands/fingers the classic MX500 style shape here suits me well, it's good to see they aren't afraid to stick with something that people like and are familiar with. Doesn't force me into an uncomfortable claw like other mice.
Unlike other palm style mice you don't have to click the right and left button in a certain location in order to ensure a proper click. The press areas are very large.
Forward and back buttons activate with roughly the same amount of force as the main buttons, they are not flimsy and easily accidentally pressed like other manufacturers.
Cons: Cord is pretty cheap, I'm not too violent with my mice but it is definitely a step back.
Compared to my old MX 500 there are large contact areas instead of feet on the bottom of the mouse which potentially create more friction.
This could be seen as a positive as part of the reason I replaced the MX500 was that two of the feet came off.
Wheel feels a little flimsy compared to more modern mice, uses the click increment style which some people don't like, especially if they are used to the smooth movement seen on the more recent Razer mice.
Overall Review: CPI or DPI everyone advertises is a useless stat at this point. For the best tracking possible you want to use default values in both WIndows and Software to maintain 1:1. Using default settings and anything greater than 1800 is just overkill.
Pros: I switch my mice between this and the Razer Naga. I use my almost broken and highly annoying Naga for MMOs. I use this G400s for FPS gaming. I highly recommend this mouse for all those heavy FPS gamers. The on the fly works great, software is easier to understand and use than the synapse I use for the Naga. Very well priced for the quality of the mouse.
Cons: The cord looks pretty cheap, but it hasn't broken or anything, it kind of worries me though. Also when I installed the software for the 1st time, it crashed my PC. I just rebooted, and everything was working fine. Also you will get some input lag with this mouse, but I use a mouse pad so I don't see it.
Overall Review: Accessories I use for Gaming:
-Logitech G400s for FPS Gaming
-Razer Naga for MMO gaming (going to replace it with Logitech G600)
-Logitech G510s Keyboard to match my G400s.
I bought my G400 at Best Buy when it was $20 off. Sorry Newegg, either way it's a really good mouse for FPS, and the best bang for your buck, especially if it's on sale.
Pros: Smooth tracking
perfect button placement
thumb buttons are great
Cons: hmm, trying to think of cons...I guess it's a little expensive, but not really for the quality you get. I guess my only con is I can only use one at a time.
Overall Review: I bought one of these and a G500 (one for my work computer and one for home). I'm not very happy with the G500 and it was supposed to be the better mouse.
This mouse is by far the best one I've ever used. I used to use MX518 mice (yeah, plural, I've burned through a few over the years). I can't say enough good things about the shape of these mice, and the G400s improves everything.
If you're even remotely considering a new mouse, this is the one you need to buy. Stop debating and hit the add to cart button.
I mentioned the button placement in the Pros section and let me tell you, they are perfectly placed. I've got pretty average sized hands and the thumb buttons are exactly where they need to be. I've never accidentally pressed a button.
This mouse also has the DPI shift on the fly buttons, and those are really handy in game. Especially if you get a game that sets the mouse speed at some ridiculous level.
I could go on and on about this mouse, but that would only slow you down from buying it.
Cons: Mouse wouldn't work on a mouse pad with the sensor, buttons were raised
Overall Review: Avoid buying from this garbage seller.
Pros: Perfect replacement for my old MX518
Overall Review: I have had a few mice since my old Logitech MX518 stopped clicking and none could compare. I found this mouse in a store (sorry Newegg) and when I picked it up it felt exactly like the MX518. I'm a fingertip user and this is the best fit I have ever found. Love it.
Pros: Fantastic mouse. All that really needs to be said.
Great sensor, tracks everywhere, shell is a classic design that has held up to the test of time. Buttons hold up to wear and tear, build quality is good (much better than the original g400 and anything razer puts out for mice) but not quite as rock solid as the mythical beast.. the one, the only, the mx518
Cons: Slightly slippery shell when brand new out of the box. Give it a week or two to break in (depending on how heavy the use is..all day gamers will notice in a couple days that the slipperiness is gone) and you'll be glad you bought it.
Overall Review: A new legend is made. The g400s is the great-great-great grandmouse of the mx518, and it's a chip off the old block in every sense of the phrase.
Pros: MX518 successor
Does feel a bit more responsive
Seems to be slightly lighter
The ability to change DPI on fly is actually pretty useful
Cons: Other than ability to change DPI on fly, doesn't seem to be a lot of innovation, if any. But then again, I was only looking for a newer version of MX518 and this fits the bill.
As far as gaming mouses go, this is really quite plain but it gets the job done for me.
