The handwriting is decent if unspectacular, it does the job, and the palm protect has worked flawlessly well for me so far. Like someone said, when it gets smoother, I'll only use Noterize. For drawings and doodles during lectures it's good enough.
The best ink app I have come across might be iDraft, although it has no wrist protection, but is free for now. Hopefully that comes in a future update. Considering getting Penultimstr because of this.
