Performance:

The first thing I noticed is that the mouse is detected on boot-up even with legacy USB support enabled in the BIOS, unlike the Copperhead. While this is a huge issue for me personally, those of you booting only one OS and/or not using a G15 probably wont care.

I played several hours of various FPS games and the tracking was very smooth on all resolutions, and I did not notice any differences in smoothness between the Copperhead and the X-750BF. The 2500dpi setting was a little too sensitive to my taste in some games, but for Half Life and CS, I found myself using this setting and liking it. I’ve played FPS and RTS games as well as general browsing and office work and so far have been impressed – It’s like an MX510 with a better body texture and sensitivity that matches the Copperhead.

In my opinion, the 3xfire button is a joke. I have no idea why the packaging emphasizes this feature over the wide range of sensitivity settings. I personally never found the 3xfire button to be more useful than the left-click button in any game I played. Yes, I can fire the pistols in CS:Source very fast, but the vast majority of weapons don’t work well with this button.

As a side note, I used this mouse on both a Ratpadz GS and an Icemat. The Icemat made it very slightly easier to make minute movements, but I believe that the tracking was slightly better on the Ratpadz GS.

Drivers:

I’ve never delved too far into my mouse setting in the drivers. A4tech’s drivers don’t look as snazzy as Razer’s, and I can’t save a bazillion different profiles for different applications, but I’m not somebody who uses a separate mouse layout for every game I play. You can reprogram the functions of all buttons accept the left-click and 3xfire buttons on this mouse, which is pretty standard. I’m stunned at the inability to reprogram the 3xfire button – this is the only way that I can ever see myself actually using this button, but then, if you could reprogram it to something other than ‘3xfire’, I guess marketing would’ve had to come up with something else to plaster all over the packaging and driver installation screen.

You can also adjust cursor speed, scroll speed, double-click speed, and a bunch of other pretty unremarkable options. For those who are curious, I’ve also included shots of all options in A4tech’s drivers. The pictures should speak for themselves.

Clicking on the “Change DPI” button opens the upper window shown above.

Conclusion/Summary:

Pros:
1. Largest range of sensitivity settings available, from 600dpi to 2500dpi.
2. Tracking on par with any other high-end mouse.
3. Well-priced — can be had for ~$30.00 USD.
4. Good overall body design; extremely light and unobtrusive cord.
5. Absolutely zero cold boot issues (this one’s personal) .

Cons:
1. General button options – One DPI switch; 3xFire can’t be reprogrammed.
2. Driver is pretty minimalistic (but it covers all the bases that I, personally, need).

Overall, I am very pleased with this mouse, and would recommend it to anyone looking for a high quality gaming mouse that doesn’t cost close to 25% of a mainstream video card. This mouse is a high sensitivity user’s best friend, surpassing all other laser mice in maximum sensitivity and operating at the same fps as the Razer Copperhead. In short, if you’re in the market for a mouse, I recommend giving A4Tech a shot.
