254 Simple and effective

I bought this probe on the advice of a photographer friend and I'm not disappointed. The implementation is simple and the certain result: printing with photoshop using the profile created by Spyder4 is the exact replica of what I see on the screen.
I even had my first return calibration.
So all is well and I recommend this to all lovers who want to work their photos in good conditions without putting a crazy price in a probe.
