The product is good as an affordable instant solution for note-taking on the iPad (my 4th generation Air). However, it has some basic negatives that it is good for someone to know first:
- It requires frequent charging, it does not charge magnetically from the iPad like the Apple Pencil.
- Sometimes it freezes and does not write well or does not write at all. This happens for only a few seconds, but when you are in a lecture, it is enough to stress you out about whether it will last until the end.
I have not used the Apple Pencil to compare, but it must have much greater accuracy in writing than this one.
In short, it is good as a product for its 20 euros, but do not expect professional work. If you use the stylus systematically for many tasks, notes, etc., and can afford it, get the Apple one.
