I bought my MFX Anti-Glare Screen Protector - Samsung M8800 Pixon -approximately one month ago. As I have had this for only a short time I cannot truly attest to its longevity but despite steady use it is, so far, not showing sign of wear. My only real caveat is that it is a bit of a fiddle to accurately attach it to your phone; after all you don’t get a great deal of practice as you attached these protective shields infrequently. I felt that the sale price a little steep but if the shield lasts it will not seem as expensive after a few months.
