No improvement of the measurement to Spyder2Pro

To make it short: The calibration is indistinguishable to a calibration with my old Spyder2Pro sensor. Supposedly makes sometime the sensor limp and distorts the measurement result. I can not understand. A panic-buying for that reason is therefore not necessary. Why did the new yet retain: With the supplied software you can finally calibrate without pullups two monitors under Windows. And that's really great. Now sees an image on two monitors (the same type) from identical. Previously, I have given myself satisfied with a calibrated profile, and the other monitor only as a File menu or device of the second order. Conclusion: The software is the plus point for calibrating a monitor only worth a new purchase is not if you have already a 2Pro Spyder. Since I can not fault also on the calibration (and never could) I give full marks.
