Question about Lenovo IdeaPad Duet Chromebook

There is now a USI Pen from Lenovo (50.-). Of course, it's top of the line with the Duet Chromebook from Lenovo.

I use the HP USI Pen with the Lenovo IdeaPad Duet Chromebook. Works well! Accuracy and latency are not quite as good as Ipad with Apple Pencil, but definitely good enough for notes and simple sketches.
