Spyder3 calibrator faulty?

[blinky]

Hi,

 

I bought a spyder3pro from fleabay that arrived today. I activated the version 3 software and ran through monitor calibration.... my monitor is pretty good to be fair but when measuring with spider it showed the green as really, really low. Running through the auto calibration it then produced a horrible colour profile with green cast as well. I've never used monitor calibration hardware or software before, it looks like this might be a faulty unit I've bought 2nd hand but anybody able to confirm/assist? Im not sure what else I can try.....

Seems it is faulty, it's missing a part on the bottom of the sensor so it's going back!
