Very comfortable to use. The only thing it lacks is Bluetooth so that the air commands can work on the Samsung Tab S9.

very good pen. I have Samsung Galaxy Tab S8 and S6 and it is amazing. personally, I prefer it over the spen as I have large hands and this one is sturdier so it suits me better.

I tried it on the Onyx Note Air e-reader, specifically for note-taking and not for drawing. For this type of use, the Wacom is much better than the Onyx pen, which is literally useless. Its friction is good for such a hard surface, although I would like it to be more. The button and the overall feel of build quality are nothing exceptional. We'll see how long it lasts. Also, I would like there to be an eraser on the back so that the finger doesn't get tired during prolonged erasing (there is actually such a pen, but I don't remember the manufacturer).

On the positive side, the surface is non-slip. Finally, the package includes 4 tips but unfortunately no adhesive case that would be convenient with the e-reader (but I suppose it doesn't matter to the users of the digitizer who buy it as a spare part).
