Needed to replace lost Pen 3's and had heard the Pen 4's were better so purchased these. The Pen 4 is more responsive than the 3. Seems to be more accurate at the point of touch. With the 3, if you were trying to click on something on your screen that was close to something else it sometimes selected the wrong item. Also the screen would not respond to the touch of the Pen 3 on occasion whereas with the Pen 4 the screen reacts every time. I think the new button placement minimizes accidental activation. We rely on Surface Pro 3 tablets for patient data entry and were experiencing frustration with the Pen 3's due to errors and slow or poor response. The Pen 4's have minimized those problems. Definitely worth the upgrade.
