Very good probe

You install the software, you plug the probe, calibrating and presto, ultra-realistic colors ... Indispensable for photo editing (screen manufacturers tend to boost the rendering of warm colors to attract customers at the expense of color realism).

Positives:
- Effective calibration, a little long the first time (2-3 minutes), but faster then bcp
- Ambient light sensor for greater accuracy

The negatives;
- Installing the software ... a bit laborious obliged to return the serial number, to connect to the web, etc ...
- For large screens (my 27 inch for example) the fleet is misplaced on cable, I have to manually flatten the probe on the screen, or fold the screen ... adjustable fleet would have been more convenient .
- The price ... all Spyder 4 sensors are identical, only the software changes ... it's infuriating to pay 50 100 euros or more for the same product, just to have a software function more ... but hey, this is the price to pay for quality ...

Nevertheless satisfied with this purchase.
