Class smartphone, unconvincing in Tablet

The pen is very well made, you can also write to him :-)
The mine is replaceable. Prima.

On my iPad mini 2 the pen works only mediocre, but I have to say that I have mounted a protective glass on the iPad, which should slightly reduce the sensitivity. Even a test without glass, with protective film was not convincing. Therefore, a star deduction.

The Android tablet (Acer Iconia Seven One) it does not work smoothly, although no protective glass / foil is installed. Sometimes you do not have to push a little harder, sometimes. Liquid operation is different.
Again a star deduction.

My test on a Samsung S5 contrast works flawlessly and without grumbling, even the text entry works very smoothly and very precisely. But actually the pen was not meant for the smartphone, but for tablets.

Overall, the pen convinced me on the tablets is not 100%. Should I change my opinion, there is an update here.
On the other hand, the smartphone pen gets my recommendation!
