Pen features include side buttons, print detection and a fine tip, with a battery life of 35 hours. Compared with the Lenovo Digital Pen 2, which offers similar pressure sensitivity (4096 levels) but potentially more buttons (2 versus 1), the improvements are not significant for standard use; it depends on your precise or artistic drawing needs. If you're not an artist, the original stylus will often suffice, making the investment less justified.
