Solid pen with systemic weaknesses

The pen I bought to complement the iPad mini. The pen comes in a convenient package to the house. The finish of the stylus leaves nothing to be desired, it is comfortable to hold and provides a good and accurate writing experience. Not comparable to the conventional pins with rubber studs tip. The pen itself has no reason for criticism. Only a missing clip was sometimes criticized because the pin together with the sensitive disc at the top can roll off the table. This is, however, subordinated to me.

Essential function is to complain about on a glass screen. After intensive cleaning of the iPad and the use for a few hours I have to say, unfortunately, that the pin slides never scratch-free on the glass of the display. I use the app notability and the write field is used here usually in the lower third of the display. This area is accordingly subject to intensive use. Here show up after a few hours under normal usage conditions very cleanly fine scratches in the glass.

Perhaps this sounds only once not very tragic, but this area is then also heavily used for writing and its mark will certainly adjust after a few weeks of use. The argument that the relatively soft plastic of the disc could never scratch the Gorilla Glass, is not relevant here. It depends on the hardness of the dirt particles entrained in writing. These have a grinding effect, if they are between the glass and the disc and be pulled over the glass. The manufacturer's argument that such effects could not adjust itself, I can accordingly no longer understand.

The pen has a great writing experience and therefore I gave him a second chance and have Mumbi Crytal Clear bought screen protectors for the iPad. This was not a good idea. The sensitivity of the display is significantly reduced by the film. To write with the stylus, it must be much more strongly pressed on the display (otherwise dropouts when writing). Even when writing the first words with increased pressure, heard and felt it scratching of the pen on the slide. Although I am of the opinion that scratches are to be tolerated on a protective film (for the film is here!), But in conjunction with the lowered writing quality, this is not recommended (with other films may also be different).

For scratching it comes down to the hardness of the material and on the pressure of the pen on the surface. If the surface is hard and the pin is only gently placed (glass), to little or no scarring form. With a soft surface and higher pressure (film), the effect increases.

My result: There are scratches. When glass it just takes longer, because this is harder and the high sensitivity of the display of the pin is only gently placed. With continuous use of a limited range (writing area of ​​notability) visible adverse effects on the glass surface are set to permanent. The effect is only enhanced by a protective film.

But to whom this matter is who will not get a more precise and better pen. However, I have returned my.
