I hope you get PID>13333 as those will not have mouse prediction.
The way to tell if you have the box in your hand, look at the clear seal stickler, if it says Logitech on it, it will have no prediction, as per Logitech:
The sensor is perfect just the shape took some getting used to. If you're a palm/claw grip it should be good. But I use fingertip grip and as the mouse is long I have no forward and back range of motion in my fingers, i have to physically move my whole arm. I think I'm starting to go claw grip cause of that, without even noticing.
I can score close to 5m/s in enotus mouse test for max tracking
LOD is very low, bout a CD and a half, maybe two
Also the cable seems very durable, I use the original mouse bungee which tugs on the cable and no issues after 4 months of use =D
Congrats for getting the best sensor on the market for £25 Edited by Scorpion667 - 8/14/12 at 2:52pm
