Have the mentioned films obtained fairly quickly, before good.The "assembly" was really easy, finally a film, wherein the support film is greater, so that one has a handle end during removal. Using a credit card can be the very few Remove air bubbles easily. The film also makes a stable (thickness) impression. The fit is also good, always depending on how to align the beginning. The only thing that bothered me a bit was that were not punched, etc. clean the lens holes, ie, the "covers" when sticking slipped under the sheet, which is rather inconvenient, because it nearly impossible to remove without imprints were. Maybe I was also just a little impatient. Anyway, I would buy the films immediately.
