What our customer's say!

"Excellent mouse, but has cord connectivity issues over time", Here is my mini review of high end mice I've tried recently.

Ideazon Reaper Edge Gaming Mouse - 3200 DPI (3200 DPI, 6 buttons): It's a decent mouse except for the side buttons. The bottom side button is under a nub that is a bit annoying to reach in the middle of a first person shooter fight. The top side button is a little nicer to reach and decent to use for knocking zombies off yourself in L4D. The wheel is annoying since sometimes as you scroll it seems to click without putting much pressure on it (which is annoying if you have something bound to MOUSE3 and you just wanted to scroll the mouse wheel). Also, it would have been nice to have two DPI buttons instead of the one (easier to "go to sniper mode"/"go to regular mode"). Currently the DPI button toggles between 5 different DPI levels one at a time and there isn't a way just to use less than that (I'd prefer just two for the above scenario...). I wouldn't recommend this mouse in it's current form.

Razer Lachesis 4000 dpi Laser Gaming Mous--Banshee Blue (4000 DPI, 9 buttons): This is the first mouse that gave me actual pain my my fingers and palm after just a couple of hours use and it has just about the worst ergonomics of any mouse I've ever used. The side buttons are in a very inconvinient location. In first person shooters you'll constantly be accidentally clicking either side's buttons since they're in the area where you grip the mouse (they're designed so you need to put "extra" pressure in the grip to click them). The laser itself is pretty decent at 4000 DPI, but it is placed in the middle of the mouse instead of closer to the front, so you basically need to move the whole mouse to aim instead of the regular first person shooter "tilting the front of the mouse" aiming. Be sure to go to their web site and use the updated drivers and firmware or you'll see a lot of "mouse jumping" problems even when you're not touching the mouse. Also I noticed the mouse buttons would register as "up" as I was turning sometimes with the mouse button down (such as a Heavy in TF2 spinning his gun using the side button, which is annoying as heck). There is also no on-mouse DPI display so there's no way to know which DPI setting you're at (one of the five DPI settings you're forced into). Anyone had any good experience with this mouse?

Logitech G9 Laser Mouse (3200 DPI, 7 buttons, weights, two grip types): I used this mouse for a bit less than a year and it is by far my favorite mouse. One problem is the connector between the mouse and cord eventually went bad and then the mouse had connection issues (Google this for more information). Other than that, it has by far the best tracking and button location of any mouse I've used. I like that the DPI switching is under the left mouse button and it is easy to tell what DPI level I currently am at. Highly recommended!

Logitech 931375-0403 G7 Laser Cordless Mouse Black (2000 DPI), Logitech NEW G5 Laser Mouse (2000 DPI) and Logitech MX518 Gaming Optical Mouse - Metal (1800 DPI): If you can't afford the G9, the models to the left are similarly good. I've used and like them, but they all had tracking accuracy loss over time and needed to be replaced (generally after about 6 to 8 months of every day gaming 4+ hours a day). None of the older models have the high 3200 DPI laser, but the G5/G7 have switchable DPI levels and generally feel good and are ergonomically nice for using over long periods of time.

OCZ OCZMSDMXD Dominatrix Laser Gaming Mouse/MSI GS-501/Cyber Snipa Stinger (3200 DPI, 7 buttons, weights): Very good for the price (one of the cheapest high end gaming grade mice). The button locations are good and so is the feel of the mouse. The default drivers that come with the mouse don't work with games well. You'll have to download the newer ones from their web site and do some special settings for your games to register the side buttons as MOUSE4 and MOUSE5. Highly recommended (drivers could use some work though).

As with any mousing, be sure to have a good quality mouse pad that doesn't need to be replaced (I used to replace those 3M Precise mouse pads about every month heh). I've been using a fUnc sUrface 1030, but there are a lot of newer ones out there now. Just be sure it's something you can soap wash and you should be good to go (no foamy or cloth pads).

"Ehhhh!", I really wanted to like this mouse. I've used the G7 for 3 years now and I absolutely love it. Unfortunately my G7 began to interpret single clicks as double clicks, and I was back in the market for a mouse.

I chose to go with the G9 this time because of its amazing "on paper" specs, as well as the glowing reviews on various sites, which really had me waiting at the bottom of the driveway for the package to show up :)

Unfortunately, no cigar.

The major problem for me was that most of the features listed on the box, ended up either not mattering to me personally or they just didn't work as well as I might have liked.

First, as another reviewer said - the choices of adjustable grips are between "tiny and pretty small". My G7 fits my hand like it was custom designed for it. The G9 seems to have been designed for much, much smaller hands.

Second, the micro gear wheel with the ratchet turned off is a great idea. Except that it takes a whole different set of fine motor skills to use effectively. Worse, the scroll wheel in "friction less" mode is truly friction-less - so you end up accidentally scrolling or zooming (if your control key happens to be depressed) when you least expect it. I'm not sure if my mouse wheel was just defective (it happens) because some of the others seem to particularly like this feature above all else.

Third, the weight tuning is something I ended up not caring for in the very least. I tried different combinations to see if it mattered - but it really honestly didn't. Maybe I'm just not the mouse connoisseur I thought I was.

Fourth, customizable LED display colors seems cool in theory - but again, I can't remember the last time that LED color was a deal breaker for me. I set it to blue and was done. I could have set it to red too. Or green. Or mauve (well, I'm not sure what mauve looks like, but you get the point.)

Fifth, the shape of the mouse resembles a pack of cards rather than the smooth filled curves of the G7. I couldn't make this feel natural no matter how hard I tried.

I really could go on.

So was there anything I liked? Actually, yes. I liked that it had on board memory for user profiles. I liked the texture of the grips and how they form fit the mouse itself. I liked the SetPoint software on Windows XP, which was real easy to use. I liked the non fray-able heavy duty cord that connects the mouse to the USB port. I liked the fact that it does have 9 buttons - if you count carefully (the scroll wheel is 3 buttons by itself). The harder part was to remember what each of those mappings did :(

Unfortunately, the positives didn't quite outweigh the negatives and I made the decision to go get myself a new G7 instead.

As with any ergonomics product, the choice of mouse is entirely a personal decision. So, the stars I've given it are a review of how well this mouse works with my hand and my temperament, and is not intended as an engineering review of the standalone product.

"doesn't solve what it claims to solve at all", It implies that you can make it fit your large hand if you have one, but
it still doesn't: your choices are between tiny and pretty small. If you
would like to try palm mousing you'll be dissapointed unless your hand is
tiny.

With weight there is sort of the opposite problem: its heavy without any
weight added. So you can choose between pretty heavy and really heavy, neither of which you will probably like much if you come from cheap mouse land. Weight isn't really good for anything, it just makes starting and stopping take more work.

The thumb buttons are soggy and ill-positioned as usual with other mice.

Haven't bother with the software so I can't say how well that works.

"Overpriced with Issues", Pros
- Sensitive
- Custom weights
- Custom LED colors
- Extra grips

Cons
- Middle-mouse clicking (pressing down, not scrolling) is INCREDIBLY stiff. Difficult to open/close browser tabs, or fly-scroll on webpages, etc.
- Mouse is too heavy for precision gaming to begin with. Using the weights would make it worse.
- Labeled as a 9-button mouse, which is ridiculous and highly disappointing. 1: You can't use the 2 buttons on the bottom of the mouse. 2: Wheel-tilting shouldn't be considered 2 extra buttons. 3: The 2 sensitivity-adjustment buttons can't realistically be used for anything else. You can bind them, but actually clicking them requires stopping and trying to find them. In practice, this is only a 5-button mouse.

Most of the features that make this mouse so darn expensive end up being worthless, and the scroll wheel kills all usability for anyone who middle-mouse clicks in browsers, etc... I returned my G9.

"Solid Piece of Hardware", If a gamer takes a step back and looks at himself, he may boggle at why he spent so much money on a gaming keyboard or mouse. But then he goes back to his Warcraft battleground or Call of Duty match and remembers why he made the investment; if you play anything more than Solitaire or Luxor on your PC, you'll want to consider making this investment too. And at the moment, the average gamer will need to look no further than Logitech's G9. I can't say the G9 will be remembered by gamers as fondly as the once-almighty G5, but once again Logitech has made a mouse which strategy, RPG, and shooter fans all can love.

This mouse's pricetag is a bit of a disappointment; it's steeper than both of its competitors, the Sidewinder and Lachesis. Not only that, but some of these features just aren't necessary. There are two grips, but wide load (the default one) is clearly the better one. Its smooth surface is more comfortable than the precision's drygrip alternative, and feels less awkward in your hands. The cord (which all gaming mouses really need for the extra precision) is braided with a durable fiber, and slides more easily than any mouse cord I've seen (though it would be nice if something to clip the unused length were included). There are two side buttons, which are easy enough to click; it would have been nice, however, if there were more side buttons. You can choose two different mouse settings; ratchet or free-scroll, but since even the lowest sensitivity for scroll is essentially out-of-control with free scroll, I don't see why anyone would want it. This is definitely Logitech's least flashy laser mouse (excluding notebook and early desktop models). It has a design that certainly demands respect at LAN parties, but it could have done with a little more flair in my opinion.

But probably the most important feature here is customization. Logitech has an easy-to-use system that lets you set up more mouse profiles than you would have any use of. Each profile can customize its LED color, individual dpi settings, scroll sensitivity, and key bindings. It's a bit hard to switch between profiles, but you really only need one, since generally speaking one type of game really only needs one dpi setting. You can have a maximum of 3200dpi, but in the current state of gaming, no one but an FPS fanatic with surgically-sound control of his hand would need more than 2200. For strategy/MMOs I use 1400-1600,FPS's in the 1800 range, with regular use at 1200-1400, just for people who need a reference point.

Ergonomically, this mouse really seems to be aimed at people with medium to medium-small hands. I have hands which anyone would call bigger than average, and the G9 isn't the most comfortable mouse I've ever held, but everyone who uses this for a day or two will easily become acquainted with the design. Wrist/forearm users will love this mouse, as will finger-grippers, but it's not exactly designed for people who move their whole arms. Large-handed gamers who use their whole arm are better suited for the Sidewinder. And of course, this is most certainly not a mouse for lefties. The main mouse buttons feel very comfortable, though it would be nice if they didn't click as much

With dpi switching that is easy to use, but not easily done by mistake, a great grip (and another which is bound to appeal to some), a durable cord, and great customization, this mouse is easy to recommend to almost any gamer.

Read this reviews before You buy...

"great for "finger grip" mouse position", This is my first "gaming" mouse to use, so am used to the generic Dell-type mice everyone gets with their computers or wireless package --- small, 2 buttons, center scroll wheel, no crazy angled shape to the design. So using those I've always used a "claw/finger" grip and lift the mouse with my fingers. This mouse is GREAT for that! The "small" cover/grip is nice and flat on the sides with a small footprint. 99% of the other gaming mice out there have a huge palm-grip design with all these crazy grooves for your thumb, long enough to rest your whole hand on, etc. If that's the kind of mouse you like, then this might not be for you as even the "large" cover/grip is really only slightly larger than the "small" grip. It's a little more contoured, but isn't gigantic where you're gonna rest your hand on it.

Great feature is you can set 5 different sensitivity points on it in 200 intervals from 200-3200. Any 5 you want! Easy to change and play around with.

Only negative I have so far is the weights. Like I said, using the "claw" grip one picks up the mouse from time to time with the thumb and pinky/ring fingers. Well the weights are in the back/rear side of the mouse, so when I pick up the mouse it tilts/pivots back a little which DOES move the cursor initially. Used to the 50/50 weight distribution and possibly mice not SO sensitive! Maybe I need to play with the weights a lil more, play with my grip, or just remove them entirely (which is a shame as it takes that feature of the mouse away). Might have to hand make a little weight at the top where the cord goes in to balance it out if I get that industrious.

"Better Than Your Old Mouse...WAIT...IT BROKE!", ORIGINAL REVIEW AUGUST 28TH, 2008

Never in my life have I found such a fast accurate mouse, where so much thought went into the design process. In fact, this is not for all practical purposes a single mouse, but you could at least consider it two different mice. Why? Well, it has two grips, which have two totaly different feels. Combine that with a totally customizable unique weight balance system, and you have quite a few combinations of custom mice right out of the box. You will probably settle on just one or two, but never have the choices been so plentiful.

Everything you get with this mouse is top notch, but you might expect that if you are willing to shell out this much for just a mouse. Sure, it might be the best mouse you've ever used. Sure, the feet glide, and the weight and grip combos are fancy, and the wheel can spin freely or spin in clicked steps, and macros and lights are customizable, but the real question is: is it worth the price?

Well, that is something you have to decide on your own.

Even if you are overpaying a bit, in my opinion, they have packaged it so well, and the performace is so great that it all seems like a good deal when all is said and done.

It's better than your old mouse. Probably better than your friend's mouse. You ought to give it a try.

NEW ADDITION 11/17/2008

This stupid mouse broke! At first, while playing Fallout 3 I thought, perhaps my character's agility is affecting how fast I can pull the trigger, and then suddenly, I realized, the left click button isn't working. Sometimes it would work, and sometimes not, and sometimes only when you pushed really hard at the very end of the button, and not where I normally pressed it at the end near the top of the mouse. This is SOOOOO frustrating paying such a whopping price for a really cool mouse which wore out after a few months with some fairly light gameplay.

You might think, this guy broke it by pressing too hard. Pretty unlikely since I am NOT a hardcore gamer, and really have used it mainly for video editing. And, even if I did break it, imagine someone who plays FPS's every night and I would have a hard time imagining how anyone could AVOID breaking it.

This may look nice, and it has great packaging and consumer appeal, but in the end, it is a cheap piece of crap.

"Really good, use it without the weights an grips", Had this for a couple months now and love it. I thought the weights would be a good idea so i tried a bunch of different combinations and it turns out i like it best with no weights, so the mouse is as light as possible. Why would you want more weight to push around and strain your wrist even more? It doesn't make you any more precise.

Also with the two included covers you can put over it to make the grip different, I tried both of those and actually like it best with neither of them on. None of the pictures show it like that because I don't think its intended to be used like that but its great.

The laser is super accurate, on dark or light colored surfaces, and anything I have put it on. The teflon pads on the bottom are huge so it moves really smooth on most surfaces. The sensitivity buttons are in a really good place, and I have never hit them by accident.

The braided fabric cable is plenty long and really durable.

The only downside is the scroll wheel is a little hard to push down for a middle click. This might cause you to accidentally roll the wheel when trying to middle click, which is bad in games because it will make you switch guns just at the wrong time. But if you are a former G7 user like me, then you have learned to compensate for it, and its not a problem.

Best mouse I have ever used period. Try to get it when it goes on sale.

"Not worth it , and here is why (Am an extremely hardcore gamer)", I was looking around for a new mouse since my so called "G9" i consider it dead and saw the G9 and thought i should drop little review of my experience with it ..
1st it says "DryGrip technology" it`s not that great from my experience with this mouse , my hand sweat and even though am using air-conditioner .. and aswell a SX steelpad . the mousepad is kinda better the regular MPs but the mouse nah , i was really excited about feature in G9 but i didn`t think it would be this inefficient in hardcore gaming .
2nd Interchangeable Grips" the standard 1 is little to big and the small one is too small .. not to mention the small grip have sharp edge at the bottom of the mouse and it would scratch off the surface of the mousepad ,Not sure if it`s only with me having bad luck of other people aswell .
3rd the surface is like my old 2 G5s and 1 G7 (feel am gonna sell it as collection ...) after just phew months of using with extreme care (have previous 3 logitech mouses with same problem so i wanted to be extra cautious with this 1) even though it`s like it sisters the surface is scratched very badly (don`t forget am using the best mousepad in the world SX steelPad 50 Euro ..) also the Interchangeable Grip started to peel off near the side buttons where i use my thumb and also near the palm spot peeled off .
So it`s so not worth it at all . i think i`ll just get G3 or MX 518 or try a Razer mouse (much cheaper and will last longer am sure of that) .
This is my own opinion as a hardcore gamer playing FPS (counterStrike source) and also using the pc for long time every day for work and gaming .
Have a good day\night and stay away from this mouse if you are a hardcore gamer .
Sallam .

"perfect for autocad", I have been looking for a replacement for my favorite wired ball mouse for quite some time and have tried several wireless and optical mice that just didn't work for me due to latency and accuracy issues. The G9 is rock solid.
Thanks amazon.
