Here it is error-free attachment is very difficult. These films should adhere by static on the screen, but, unfortunately, the adhesive of the protective film remains (which you have to pull before attaching) to the film back. This adhesive attracts dust almost "magnetically" to. In addition, the adhesive is already itself contaminated with dust. The film is further so stiff that they can not compensate for even small bumps of dust grains below the perception threshold. Six films to read only one attach right away without inclusions. Another shortcoming is that there is no release liner to the top, which can already cause scratches in the attachment.
The Folienen were however very accurate fit, but this also made a few problems. The film was not positioned exactly they stood out in the corners, because the frame of the Galaxy R is slightly increased.
A few months earlier I had bought films from a different vendor for my phone, so I can compare anything and know what would be possible. These films were very similar price. Unfortunately Versanstkosten time were so high that the costs were in no relation to the product. However, these films were protected on both sides by a protective film. The installation was a breeze (no inclusions) and small dust grains were easily concealed. (-> Mumbi screen protectors)
In summary it can be said:
Pro:
- Price
- Very precise fit
Contra
- Adhesive residue with dust inclusions
-> Error free mounting very difficult
- Any protective foil to the top
Thus, I can not make any recommendation to buy this product.
Tip:
If the film is contaminated with dust, soaping the film with a detergent and rinse thoroughly under lukewarm water. After that drain and still muster with the residual moisture on the display. So an error-free attachment should be possible. (Me it is at least as successful ;-))
