Super note ceramic stylus nib on onyx device

[Lyndilsaid]

Hi all, i love eink device for note taking but the need of change the nib after sometimes is annoyng for me.. So i read about the new supernote ceramic nibs. It seems that all fonts (ex goodereader and my deep guide) dont raccomand to use it on another device, because it can scratch the screen also with produrotrction.

Honestly it seems strange to me, so i want ask if someone that have tryied this on a boox device can give me a feedback. did someone try it With a protection? I have a max 3..
