After the first original HTC film was now scratched so that one has seen it very clearly, had to be something new. Since the HTC film did not fit very well, I once tested something else. This film fits unfortunately "too well", which means that you must have hit the right note at the first attaching or she is down on the edge and not on. I then tried to peel the foil again and reposition, but that is almost impossible without the support film. So it was good that the three films in the package were. The second is then also worked the same. For me personally, it would be enough if the film 2mm narrower and 2mm shorter than the display would be one and therefore has round about 1mm square to z, b, to make installation easier. But others would be safe again complain that it is too small. The one star I do not draw from because of the Assembly, but because the film is not as scratch resistant as it is in the description. I have the same mounting a can not be overlooked scratches in it, probably by the doctor. That should not be in my opinion. I once bought a sheet of any Asian manufacturers on ebay and has endured a complete mobile life, without only a little scratch on it was. This is something I would like to see again.
