Hi, We calibrate all of our screens including laptops at the start of our working week using a "Spyder 4 Express" and would not hesitate to recommend them.
At first we thought they calibrated just a shade on the warm side compared to what we had been used to but must admit to prefering them now to our previous set up.
It is essential though to let your screens warm up for at least half an hour before calibration.
We print mostly to Fuji paper using Epson printers and very seldom have any problems with colour balance on prints.
Hope this helps.
