I got the Adonit Jot Pro a week ago, ordered at end of October. I got the Pro because the normal one wasn't available. First impression : it's really, really beautiful.
Second impression : I think there should be a user manual somewhere, because I had no idea what it would look like and the plastic disk surprised me a bit. So before doing anything foolish, I searched on the internet and saw that it was normal, and that it was not something random to protect the tip.
Anyway, then, I took the TF and tried writing something, I was not very happy with it. I'm using the Writepad Stylus application, and it skips all the time, like I can't even write four words before it stops reacting. I've tried changing all the parameters of the application, calibrating it, etc., but nothing changed.
For drawing, it's ok, but I bought it specifically to take notes, and I can't do that
I don't know if I've got one of the "skipping" ones, I hope not.
I don't have any sreen protector, I'm running the latest firmware.
