First I bought the Invisible Shield invisibleSHIELD Screen Protector for Samsung Galaxy S i9000 to protect my Samsung Galaxy S which is indeed in a completely different price region. This made me very disappointed. The films could not be right from the backing paper you had to replace the paper literally scrape while the foil soiled heavily. Added to this was still the fingers remained heavily dependent on the film, so that the operation was deteriorated. So I looked around and decided to use these films for a different product. Although 6 unit costs only a fraction of the Invisible Shields has convinced me much more. The films are very easy to apply, much faster than the Invisible Shield. Even the included cleaning cloth is very good, my screen was completely freed from dust, there is nothing under the film, moreover, no bubbles or the like are under the film. Perhaps the film shooter is not quite as good as the Invisible Shield or wear out a little faster. However, since several are and also the attachment is very light should also be no problem. All in all I can only recommend the product. MfG
