The biggest complaint I see around the net is that there is a stutter/jumpiness when using the
Dual SFX Frag Pro on the PS3. I experienced this, myself, quite notably on
Singularity when setting the
Dual SFX Frag Pro's sensitivity setting to 5 or above. When testing it with
Call of Duty: Modern Warfare 2, this effect was much less noticeable; moving the camera with the Right Analog Stick resulted in very fast, smooth motion up to about 7 or 8. On the highest setting, I observed the same stuttering, but to a lesser effect.
This stuttering/jumping effect begs a better definition, so I'll try to clarify: If you've ever used a mouse with the scroll wheel set to scroll several rows with each click, that's sort of what you experience here. Not only is this jumpiness annoying, distracting, and quite possibly nauseating (if you're predisposed to motion-sickness), it also jumps in a set amount of distance, creating a "snap-to-grid" sort of effect. If you're trying to aim at something small or far off and your sensitivity is all the way up, you might find that you're just to the right of it. Then, with the smallest possible amount of movement, your view passes it up and is now just to its left. Carefully moving back to the right ever-so-slightly will jump over it, again, to the same spot you were at before, as if those two spots were on a grid and you could only move two spots on the grid.
The thing to realize, here, is that the Dual SFX Frag Pro is built to give you the ability to tweak the sensitivity up as high as you want it (and can handle it). This will likely vary on a per game basis, possibly even being different for different maps or setups, but it's not necessarily the sort of thing you'll need to change on-the-fly constantly. If you use the Dual SFX Frag Pro at a high sensitivity setting, you can use the (Frag) button to instantly temporarily drop the sensitivity low to allow you to dial in your aim.
I have seen zDD, Professional Gamer and Splitfish Evangelist, talking about Modern Warfare 2 for the PS3 and saying that he sets the in-game sensitivity to the maximum setting and the Dual SFX Frag Pro sensitivity setting to about a 3 on "The Pit." A 3. It's not a contest to see who can set their sensitivity the highest and still move around; it's about control and efficiency. The Dual SFX Frag Pro gives you the control to set your sensitivity where you want it.
I found the mouse to be a comfortable size (but, then, my hands are large, so consider that), but I did find that the trigger button (Left Mouse) could sometimes be difficult to push. I wouldn't want it to be a hair trigger, but it would be nice to be configurable or adjustable. Many buttons and the sticks are, but not the mouse buttons.
I would have liked to try using the Dual SFX Frag Pro mouse as a system mouse on my PC, but, while the mouse can be set into a normal mouse mode for the PS3, this doesn't appear to be possible on the PC.
So, the question is whether to get the Dual SFX Frag Pro or not. If you're looking for the highest level of control over your FPS games and you want a competitive edge, the Dual SFX Frag Pro combines the ease of use of a gamepad with the control of an optical mouse with sensitivity adjustment and then throws responsive wireless connectivity on top of that. And if you're looking for a split controller for use with PS3 and PC games, then the Dual SFX Frag Pro might be perfect for you.
