Philips Doppler-laser sensor has issues with moving when you lift off the mouse from the pad. Most professional shooter players use relatively low sensitivities and somewhat frequently lift the mouse off the desk to reposition it. I doubt any professional shooter player that isn't directly being paid to use this mouse would use it.
also higher dpi does not mean more accurate. Almost all if not all professional shooter players use 900dpi or below. Using a 8200dpi sensor is directly marketing the mouse toward casuals that don't know better, and having higher max dpi directly harms the mouse's performance at every dpi by adding smoothing, aka, lag and makes it less appealing to professional gamers.
If I were a pro gamer looking for and needed a mouse, this would be at the top of my list of what not to buy. I have never owned, seen or heard of a good mad catz product, I'm confused how they are even in buisness still.
I have tried the original cyborg mice and the rebranded Mad Catz version....thats all you need to see to determine that Mad Catz is a joke. So glad they let Saitek still make their own products. Their new joystick and throttle system isnt covered in shiny colorful plastic and dumb cat scratch logo's. Please, please please please don't buy this piece of junk people.
