This is my third RaspPi touch screen. I started with a 2.8" then a 5.5". Both were good displays and great learning experiences. Several hours of learning experience. For each one. This 7" display, however, worked correctly the moment it was attached to the Pi3 and powered up. What a revolutionary concept. Now I am forced to spend all that 'learning' time on learning something even more useful. Mind you I am long since retired and have time to spend learning whatever I wish. Not everyone does. Love this display.
