What interests me is the sensor and the jitter reduction. I want it to go with my gaming laptop. When I have my laptop, I tend to use some non-traditional surfaces for my mouse, and I've noticed a lot of jittering with my Logitech 600.
While most professional gamers use lower CPI settings like 400 or 800, TrueMove3 delivers incredibly accurate, true 1-to-1 tracking without using jitter reduction from 100 – 3500 CPI. At CPI levels above 3500, our custom SROM delivers the most effective jitter reduction for 1-to-1 tracking. TrueMove is the first optical sensor that will never let you down. If you missed the shot, practice.
I had a Sensei mouse for 9 years until i had to replace it as it was crashing my PC. Now have a Rival 600. It handles jitter the same way since it has TrueMove 3+
