Welllll----after using the Jot Touch 4 for some time, I am forced to admit it was a disastrous purchase.
Be aware that I do not use it for drawing, so the pressure sensitivity is not a big thing for me. I do appreciate its high quality construction and the way it feels in the hand, BUT---.
It does not work well at all with Good Notes, my favored writing app. Sometimes the stroke is simply not recognized, while at other times (when I am touching the screen lightly) the last stroke appears and then immediately erases itself. Though I haven't tested it extensively on Noteshelf, Notability, and other writing apps which I also like, the same issues seem to crop up.
But the worst thing is the action of the touch nib. There is apparently an internal shaft attached to the point which ratchets up and down as you press and release, emitting a funny "cricking" sound in the process. Both the erratic and the sound are annoying.
Bottom line: I reach over for my conventional Jot or fiber tipped stylus and get better performance. The Jot Touch 4 is a lousy product from Adonit that is way overpriced.
That said, I have preordered their new 1.9 millimeter point stylus in the hope that it will be better than the Touch.
Just wanted to update, well actually reverse, my earlier enthusiasm for the Touch. Hope it helps you in your search for a great stylus.
