NXTPAPER 70 Pro compatible stylus list
I own the official 70 pro stylus case, but since not everyone is able to buy that yet I wanted to do a quick list of styluses that I found worked (and how well they do with screen protectors)
The official pen works perfectly even with a screen protector. Pressure sensitivity works fine.
The pen for the "tcl stylus 5g" works exactly like the original, it also works well with screen protectors. And has pressure sensitivity. And it's magnetic so you can attach it to the back of a magsafe case! Also you can get them for only 5 bucks on aliexpress. That's why I would recommend this one over the official one
Lenovo integrated pen (came with my Thinkpad l13 yoga). Works with pressure sensitivity. But the pen only works good if you have no screen protector. With a screen protector the line gets broken all the time.
NXTPAPER 14 pen: it works, pressure sensitivity also works. But it also didn't like the screen protector at all, the line got broken up all the time. (I didn't test this one without protector, but I think it would work better without one, like the thinkpad pen)
If you got any infos about which styluses work please write them in the comments!
