But (yes, there is a "but) the rubber tip using stylus for tablet / smartphone that can be found on many modern pen (or advertising) is proving to be much less efficient than others that I ''ve tested even on promotional pens ... It works but it's not pleasant, the rubber is too firm, you have to press firmly, which is not the purpose of a capacitive screen of a smartphone or a tablet (and I said that I tested on several devices).
We note especially the quality of finish and precision that make the brand reputation, but remains the point of the touch pen making "spot" from the price of the product.
