I had purchased this product right after I purchase my iPhone 4...which was quite some time ago...However the screen protector is still working quite effectively after what has been almost a years time. I have not had to replace it or anything. Its easy to clean with the cleaning cloth that hs been included with the screen protectors. Recently I had found a HUGE scratch on my phone...it looks like a scratch that would have been made by my keys, as I had both my keys and phone in my pocket...the same pocket. Any ways, I was very ALARMED and worried...however I checked my phone by pulling back the screen protector AND behold NO, I said NO damage occured to my actual screen. The screen protector did its job, quite impressively and effectively, and PROTECTED my screen. :o)
Excelente producto diria yo, a diferencia con lo que te clava el fnac que es igual a este protector y que por solo 2 euros puedes estar tranquilo de que no se te va a rallar la pantalla de tu iphone4. Asi que se los recomiendo en si.
En cuanto a la entrega, fenomenal rapida de acuerdo a los dias estimados, el producto muy bien protegido en una enorme caja jejeje... pero siempre estubo sano y salvo :).
