The Wacom One Pen (CP-913) was design to work with the Wacom One 2019 GEN1 (DTC-33) which was one of Wacom's consumer pen display.
This pen is a very "consumer" pen, and it has a OK performance but is absolutely not as good as Wacom's Pro Pens such as the Wacom Pro Pen 2 (KP-504E).
Two things separate this pen from Wacom's Pro Pens:
IAF
Buttons
It has a higher IAF and thus requires more force to register a stroke. If you've used other Wacom Pens you may be very disappointed in this pen. If you've never used a drawing tablet before It may not be as big an issue.
A Pro Pen 2 has an IAF of <1gf. Which is EXCELLENT
Apple Pencil GEN2 has an IAF of <1gf. Which is EXCELLENT
A typical non-Wacom pen has an IAF of 3g which is GOOD
The CP-913 has an IAF of ~5gf which is OK.
Its max pressure is about ~350gf. This is good.
Unlike the vast majority of drawing tablet pens which have 2 buttons, this only has a single button.
This successor pen CP-923, is awful. See my notes: 7P notes: Wacom One Pen GEN2 (CP-923)
