Pros great feel, amazing responce, on-the-go sensitivity changing
Cons software not supported by Windows 2000
Summary i just got this mouse yesterday and i already see a huge difference in my gaming. i've mostly played CS:S with it and im already shooting more accurately and therefore, getting more kills. this mouse felt alittle weird at first but now fits perfectly in my hand. im disappointed that the software for it isn't compatible with Windows 2000 but at least it comes preset with 400, 800, and 1600 dpi so i can adjust the sensitivity alittle. i dont know if ill be able to handle 1600 dpi because that's pretty extreme, even 800 dpi is pushing it but at least i kno i can go that high if i really need to do some serious twitch-gaming. overall, great job logitech on an amazing mouse that every gamer shouldn't be without.
Pros Very comfortable and egromatic; many extra buttons; nice response; Sensitivity switching; application switching; extra buttons are easy to reach; relatively long wire; supports pretty high 1600DPI
Cons Right-handed only; optical rather than laser; doesn't support 2000DPI (which is a little much anyway)
Summary Though the MX518 is a mouse of the previous generation of gaming mice, it is much better than most of the mice of the current generation.
The MX518 is very, very comfortable, and never annoying or straining to use. All the buttons are well-placed. Its comfort is where the Razer Copperhead fails, the latter not being very egromatic at all.
The MX518 has two extra buttons for games and applications, and sensitivity switching/application switching buttons. This is where its successors, the G5 and G7, fail. The G5 and G7 lack a second thumb button and an application switcher.
The MX518 is an optical mouse; therefore, it will not be exactly as accurate as the current generation but will definatly be accurate enough. It supports up to 1600DPI, which should be good for FPS's. Though the current generation (excluding Microsoft's offering) supports 2000DPI, 2000DPI is a bit too sensitive for most cases, anyway.
If you don't need an application switcher (which most don't) and a second thumb button (which less hardcore gamers don't), definatly go for the G5 or G7. If you want a flashier mouse with as many buttons as sensible, go with the Razer Copperhead. But if you want a great mouse with great potential for gaming and normal use and great comfort, look no further than the MX518.
Pros Comfortable; sleek looking; good button location; good scroll buttons; easy to use; good response time
Cons mouse pad does make a difference in how it works
Summary I have the MX500; which is basically the MX518 w/o the cool color; mine is a plainer silver; i spend many hours picking out the right mouse; and this has a great response time... a lot faster than my old hp mouse; i found my skill in first person shooting games went up quite a bit when i got this mouse with a much better refrest rate. It has two conviently located buttons on the left side for forward and back...which i use on web browsers all the time. Then it has a good speed continuous speed buttons below and above the scroll wheel; bottom line is that this mouse cannot be beaten by any other wired mouse; this is the BEST!!!
Pros + Comfy in hand
+ Good weight, not too heavy nor too light
+ Cool design
Cons - Mouse wheel feels loose after few months
- After 7 month, left button began to work bad - when playing games, sometimes a weapon does not shoot at all or shoots in burst mode instead of auto. That's when I do clicking with left mouse button.
Summary Maybe I have got a faulty mouse, but I'm not going to buy Logitech mice again... think I'll try some other brand.Now problem disappeared, just did not understod why it was before.
By the way, as an example, I had a cheap A4tech non-gaming mouse for 6 years without this issue.
So.. nowadays a brand name does not say anything, as it's all assembled poorly in poor countries by the poor people, so don't expect it to be reliable.

Pros Easy and smooth to track, Adjustable DPI on the fly, Cheap, Lightweight, Plug and Play, Good precision, comfortable grip, 2 thumb button instead of one (G7, G5)
Cons Right handed grip (Not suitable for left handed users), Cant work on a MAC
Summary This is undoubtedly one of the best investment I had made a few months back.
One of my friend who bought a G7 complained that it was too heavy to his liking due to the batteries that were under the mouse.
The MX518 is Light weight, making it so much easier to glide and comfortable with the right hand grip.
It's so easy to install as it is plug and play, making it noob-proof.
MX518 also allows you to adjust DPI on the fly. It's really irritating to exit a game specially just to change your DPI.
2 thumb buttons are also available for great experience of web surfing and added unfair advantage in games; specifically for additional game control binding (e.g. reload, switch weapon)
However, the only setback is that it's for right hand users and would take a while before left hand users (my sister) can get used to it.
Sidenote: One of my friends tried the MX518 drivers and it did not work on a MAC.
My Take: Definitely one alternative to consider if the G5 and G7 is not within your budget, provided you're fine with the 1600 DPI. My best investment for fragging on Quake.
