"Has small flaws, but a good mouse nonetheless"
To start off, I would say I got lucky when I ordered my Fatal1ty laser mouse. I've read many reports of this mouse not working after a month or so, with a double clicking issue. I am happy to say I did not get these problems.

Te design of this mouse is very different than other mice, especially logitech mice, which are held by your whole hand. This mouse is held by the "claw," which basically means you hold it with your fingers, and your wrist can rest on the table. Personally, I prefer slightly smaller mice to the giant logetech ones.

The laser tracking on this mouse is extremely smooth and accurate. The polling rates, as you may or may not have read, are 1000hz (which means that it refreshes its signal 1000 times a second). The dpi at max is 2400, also helping out the smooth and accurate motion.

The mouse buttons require a bit more effort to press than I would like, but it's not something that I'd worry about. It takes a while to get used to the button on the far right, since most mice don't have that button. The dpi change button, right under the mouse wheel, feels a bit too hard to press to change on the go, but I've never had to do that in middle of a game before. The thumb button is nicely placed so that to press it, you roll your thumb inward and you press it.

The weight system does it job in this one, although with the heavier weights, you'll need to secure the weight with something around it, such as tape. There's a small issue of slight wobbling of the weight when you move it around.

The teflon feet are large and do a very good job of keeping the mouse sliding smoothely on the table.

In terms of overall feel, the mouse feels great. There are a few small issues here and there, but the overall performance of the mouse overshadows these.

"Buy this mouse in March 6, 2007"
PRO:
Displacement smooth

Against:
Buy this mouse in March 6, 2007. alone it uses it 1 month playing Battlefield then 2 I have used it windows the months later and button left accent of working.

If it uses the option 2400 CPI the cursor it is unstable (it is as if it was an overcloking)

The sound of the bellboys is strong, I cannot use it to at dawn (it is listened in the whole house)

I am surprised that Creative a respectable company has made a mouse of so low quality.

I don't recommend it.



"Improvement over the previous model"
If you have used the previous model of the Fatal1ty mouse, you will be pleased with this model. The real big change that makes this a worthwile purchase is that the response is much smoother than the previous model, which will translate into more responsive and finer control in first-person shooters (FPS) such as Battlefield 2. One other change is that the ring finger button is a little harder to press, which some find to be an advantage. The interchangeable weights are great for modulating the response that you need. If you are using a conventional mouse for gaming, it will take some adjusting to get used to the shorter profile of the mouse, but once you do you will probably not want a different mouse ever. I honestly will not go back to a regular mouse because in my opinion this is the best gaming mouse available. It has buttons in all the right spots and lets you dial in the weight to suit your gaming style. I highly recommend it to all FPS players.

"Pretty good mouse, but click resistance too high for my tastes."
Fits my hand nicely, with my pointer, middle and ring fingers each on a button, and each in a nice, curvy indent. There's a ring-finger click, too, which I've never seen on a mouse before, but it's comfortable. It defaults as a forward button.

This mouse is meant to be gripped by the pinky and thumb, with your wrist resting on the pad. Larger mice, like my Logitech MX518, require you to use your whole arm to move. Before logitech, all mice were nice and compact, and fit my hands nicely. Logitech's making it hard to find a mouse with nice ergonomics functionality anymore.

One user mentioned he kept accidentally clicking the resolution button while using the scroll wheel. I'd just like to respond: Maybe you have an early build, because I find it difficult to even press the button! I actually have to use a little forearm muscle to press that button.

Speaking of button action, the middle mouse click feels (and sounds) good. The left, right and far-right, and back button clicks, however, require a bit more pressure to click compared to other mice. This hurts my accuracy drawing with Photoshop, as I am missing late and release late, drawing multiple brush strokes. I'm finding it hard to get used to it. Also, since I have to press down harder, it adds a tiny bit more friction to the fluidity on the mousepad, which hurts accuracy more. This is my main reason I'm not satisfied with the mouse.

The scroll wheel's noise level, on a scale of 1-10, (1=worst - 10=best) gets two different ratings - scrolling down gets a 8/10, while scrolling up gets a 6. This seems to be a common trend in other mice as well, with up being louder.

The red circle on the top of the mouse is an interchangeable weight. I've found that the weight rattles around loosely when scribbling in Photoshop, but I guess it's not too big a deal, and it doesn't move at all if you have your middle finger resting on top- however, this mouse wasn't meant to be held like that though- it's meant to be held in a relaxed claw-like position, not with your palm resting on top.

As far as form factor, it's a nice shape with contours for all my fingertips. It's a comfortable mouse sitting still. There IS a seam in the plastic where my pinky grips, though. I find myself re-positioning my hand for whatever's slightly more appropriate in some scenarios, so sometimes the seam is out of reach.

The mouse has a high CPI, which is nice for some people, I guess, but it's overkill, in my eyes, to have sensitivity so fast. I'm never going to use anything higher than a normal mouse. I like to have a slower mouse speed for fine lookspeed, precision Photoshopping, and accurate desktop pointer use. I have it set at 2400, with my WinXP mouse settings slide down to the 3rd notch. I guess having more reports per inch is better, but I have to counter it by lowering the speed. I'm not sure if that defeats the purpose or not, but my understanding is that it still reports 2400 points per inch that way, but moves the pointer slower.

For what it's worth, the $[...] rebate listed on Amazon points to a .pdf for a $[..] rebate on a keyboard- I emailed Amazon, and they told me it was MY responsibility to contact the other people. Meh.

This mouse isn't worth keeping for $[...], and it sure isn't worth keeping for $[...]. The click pressure simply throws my accuracy off too much. Give it a try, though, because we're all different. ;)

"Not a fan"
I purchased this mouse and used it for around a week and simply could not get used to it. I have large hands and could not find a comfortable position. The ring finger button was often pressed instead of the right click button and I found myself hitting the resolution button when using the scroll wheel during gaming. I ended up returing this mouse in favor of the Logitech MX Revolution. It is a much better fit for me.
