I have held for a long time not so inferior protectors for Dispalys in his hands. Only the cheap price and the fact that there are 6 pieces films have kept me from a complaint. The films can not be compared with conventional "high-quality" protectors for Smartphone & Co.. These bring some stability and a good silicone adhesive layer itself. A bubble-free application was not possible for me in the greatest of care and experience. The tempering / scratch resistance can also be much to be desired. Only the fit should be assessed as well. These films are only recommended for absolute bargain hunters, take the little blemishes and short lifetime purchase. But one gets indeed 6 pieces to the spot price.
My Conclusion: Come for me again in question. I can only advise against any serious user of this product. Rather spend 4 euro for a good film.
