Customer Reviews

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.
