The first thing that sticks out is the package of extra feet. This mouse uses 4 feet with an estimated lifetime of 2.5 million meters, and the extra feet ensure that you’ll be good for another 5 million or so. Other than that there are no surprises.

Since many of the physical aspects of this mouse must be evaluated on a subjective basis, I’m going to include some pictures that should give you a pretty good idea of how this mouse is shaped, and hopefully a good idea of how comfortable it’ll be for you. For comparison, you can also see the Razer Copperhead.

I’ll say in passing that the shape of the X-750BF reminds me of the Logitech MX 510.

Feel and Comfort:

I found the X-750BF to be quite comfortable – reminiscent of my old Logitech MX510 but with a nicer, easier-to-grip texture. The button layout is good, with the finger buttons, scroll wheel and ‘3xFire’ button easily operable. I checked to see if I could press both the 3xFire button and the left click at the same time, and while it was possible, I have to say that it is very easy to feel the difference between the two buttons, so I think mistakes here shouldn’t be a problem.

The snakeskin like patterning you see in the pictures of the X-750BF has a slightly rough feel to it, rather than the perfectly smooth, hand-grease-accumulating clear-coated plastic of the Logitech MX series. I definitely prefer the finish of the X-750BF, and have not had a problem with hand sweat (except the thumb, noted below) or my grip slipping when using it. There are other versions of the X-750 (red and black) that have the more usual smooth, clear-coated plastic surface if you prefer.

The thumb grip sure looks like a good idea, but for some reason the plastic material here seems to make my thumb sweat more than usual – and noticeably more than the rest of my hand. I only noticed this while playing intense FPS games such as F.E.A.R. and PREY. I didn’t have trouble holding onto the mouse, so the grip works, but I think it’d help if it were made from a different material – for instance, the same material that the right/left click are coated with. This issue is probably subjective.

The DPI-switching button was also easy to operate. There is only one DPI button though, meaning that if you use 2000dpi to run and gun, but prefer 1600dpi to snipe, you have to press the DPI button five times to cycle through all the other DPI settings. The indicator light is helpful for determining what DPI you’re currently using, but glancing at your mouse (and in the case of some DPI settings, waiting ~1 second for the indicator light to blink) isn’t something you want to be doing during a death-match. I personally didn’t have a problem with this, but I generally don’t change DPI settings during a game. Logitech makes laser mice that have two DPI buttons (increase/decrease DPI) near the scroll wheel, and the Copperhead also has two DPI buttons (that can be reprogrammed) on the right side of the mouse – although you may still need to press the dpi buttons more than once depending on your preference.

In my opinion, the thumb buttons could be moved further back. I hold my mouse by placing the base of my wrist on the mouse pad and using my fingers to lift/move the mouse while my wrist is stationary. In order to easily reach both thumb buttons easily, I have to adjust my grip by sliding my hand a little more forward over the top of the mouse. It’s not uncomfortable, per se, but it changes the way I’m used to moving it. This is a very subjective point, and in the couple weeks I’ve had the mouse, it’s pretty much become a non-issue.
