delivered on time (good), is easy to install (good) but having a sony xperia z1 compact with two fragile glass facades and easily scratchable I bought this product for optimal protection as he boasted. But to my surprise after a day and being careful protection scratches as easily as if there were none. micro-stripes appear on the back cover to which it is put. I do not recommend this product it only serves to protect in case of fall but I do not dare try.
