Hi there,
I just discovered through this subreddit that using the fine liner extends the tips’ life, but no info on how long exactly ?
I just got my rM 2 and I like it a lot, I think I am going to use it like 6+ hours everyday, mainly for math problem solving. I ordered it from the U.S. since it’s not available in my country, so it’s not easy for me to get replacement items.
So far I’ve been using the original nib that came in the reMarkable stylus for about four months. I don’t write on the tablet all day, maybe 30-45 minutes of actual writing each day.
This page has more details about my experiences with nibs, including my take on titanium nibs. Short version - I have them but I don’t use them, mostly because I noticed a very slight difference in how it feels, and because I don’t want to take any chances on damaging the screen.
