work very well

Processing seems at first (and second) glance quite good, although I can not say anything for durability (are only about a week in use).

Supplement: Meanwhile, I have already the second time ordered a pack of stylus pens.
After about half a year of regular use, the rubber tip is so nice and slowly broken and the pen just does not get as good as at the beginning - the tip is then simply "consumed".
Price / performance of these Stfite is still in my opinion very good. Pins, where you can swap the tip, cost far more and also do not work better (I have at least found anything yet ...).
