Tip pen Hipen H7 , freebook

After purchasing a corebook x, a larkbook x (better aesthetics but obvious problems with the n5100 processor, too slow) , I am the new owner of a Freebook (N100) since yesterday.

I have a problem…
I tried the pen right with the Windows notepad. I don’t know if it’s a problem with the notepad app, but if I try to color, the pen loses signal after a while, to continue I have to remove the tip and start again.

I’ll do more tests with specific programs

I also wanted to ask, where to buy the Hipen h7 pen tips?

I can’t find anything on AliExpress, are the tips of the Xiaomi pens okay? I saw that they are similar.

Thank you

Unfortunately we do not have Pen tips to sell as replacement.

Greetings.
I find it unwise, what do I suppose I should do if the supplied tips break? buy a new pen? as long as it’s still on sale at the time it happens…

I tried to buy the tips for Xiaomi stylus on AliExpress…

they work well but they are not as stable as the originals…

Does an adaptable replacement like the original exist? the lenovo ones?
