At first I was having some isolated issues with the MS-3, but I did eventually resolve them. I left the mouse with all of its default settings intact aside from customizing the LEDs and changing the DPI. In games where I was spraying bullets like L4D2, I didn't have an issue, but I booted up BF3 and the first time I tried to snipe someone, I found a jitter in the tracking that drove me bonkers. Even in things like photo editing, small movement were jerky and almost like the mouse had to catch up at times. What I found will resolve this issue had nothing to do with the USB port or anything I did, it just takes turning on the pointer acceleration to make it all peaches and cream again. Once I got this mystery solved, I really did enjoy my time using the MS-3. Even if it does force your hand a bit more forward on the mouse than I tend to like, with a few days to a week with this mouse it is really easy to get used to, move around, and even pick up since all five of your digits are already on the mouse, grip is not an issue.
After I was able to pin point the performance issue, it is more a subject of feel and the feature set. The software does a really good job of giving you full control, and even with an adjustable LOD, you won't get stuck on the lowest setting like I have found before. Low is about 2mm, medium is around 4mm and high setting will give you around 6mm before the sensor stops tracking. Along with customizable LEDs, customizable button layout, and the Macro control; besides moving by telekinesis, there really isn't anything more to ask of this mouse. I really did enjoy the time I sent using it and much of that is all in the way the mouse cradles your hand and makes your whole hand and this mouse one solid component with very little drag.
Speaking of drag, we need to discuss the Surface 1030 L. This also helps the MS-3 do its thing a little better. As always I tested the MS-3 on various mats along with the one provided, and I will say I had the best experience on the Surface. With the rough side up, you have less points of contact and much less friction on the mouse that allows for fast jerky motions to be very easily done. On the flip side, where the Surface is much smoother, it does make for more friction, and thus slows you down for things like photo editing or graphics design. The Surface 1030 L and the MS-3 are a match made for each other, and I do suggest you pick this up to fully enjoy the MS-3 to its full potential.
Even though I do wish these components were a little cheaper so that more of you would go out and try for yourself, I do feel their pricing is justified. I have other $40 mouse pads, and they did not do as well as the Surface 1030 L did in my testing. Even on the smooth side, there was a definite slickness that cloth mats can't give you. The MS-3 is well appointed and does give you a lot of options, and as compared to the other mice I listed in the intro, I do feel that FUNC did price the mouse correctly for the market. I know $80 for a mouse sounds kind of steep, but if you are serious about gaming, this is sort of the same idea as buying a mechanical keyboard.
Those in the know will spend a bit more to get a product that fits them exactly for their needs, and I think both the MS-3 mouse and Surface 1030 L will deliver on this for a lot of users.
