A friend of mine bought one yesterday, and I tried it out.
The cool thing about this mouse is it's AMAZING tracking... It's a bull%^&* argument that it's for CAD and businessmen! What do they ever need to move it at great speeds for?
I've got an MX510 and so far it's the best all-round mouse, and even it does not compare to the exquisite tracking (meters/second) of this lazer mouse. Firstly you need all excelleration OFF, then in a game, more it FAST to one side, and then back the exact same point... and voilla... you are there! What executive needs this!!!?
I'm a low sens player, which mean that my movement is flowing and I pack an average of 45% rail accuracy in Quake... this mouse if really good with accuracy, but if they just left the sensor on while picked up, then it would make moving actuallt plausible... since like most low sens players I use a huge mouse pad, and pick up my mouse constantly which makes this mouse unusable... all they needed to do was to keep the sensor on for a bit longer!!!
I then tried playing it as high-sense, and it does become a bit easier to use, since most high sens players hardly ever need to lift the mouse... it becomes bareable in this mode, but still not good enough.
The MX510 is still the best mouse... And I have used MS ball-mouse, Razer Boomslang 1000, MS Optical versions 1.0, 1.1 and 1.2, MouseMan Dual Optical and MX310....
-sgrug- (I also have a cordless Dual Optical Mouseman, but it has a severe glitch that you cannot press a button without interrupting the movement slightly which makes strafe/circle jumping in Quake impossible if you use the mouse to jump.... I have since also swopped to using SPACE as jump anyway...)
I'm sure this mouse should be 'hackable' with some solder etc.... which would then make it the ultimate... I love the fact that they made it work at 125 unlike ALL the other corless mice.
PS: PS2 adaptors still give better performance though... up to 200Hz and beyond... but you would need Linux to truely appreciate it's repsonse rates for this...
Hope this was enlightening to all you prospective buyers...
PS: On another topic, the whole mirror thing. The mouse is obviously outside the visible spectrum, and thus the 'mirror' may not be as mirror-like at those frequencies and may or may not work... hence the Box disclaimer... Just my 2c
