no wonder this is so cheap, the quality is pretty poor. after you stick it on the iphone, it reduces the sensitivity of the touch screen and you can feel that there is a thick plastic on the screen. I bought a better quality one after this and can immediately feel and tell the difference. the better quality ones make the screen much clearer.
don;t waste your money on this.
on the other hand, if you don't mind about quality,like my husband who is still using his after 3 months, it does protect your screen.
