Made from a "unique, multi-layered plastic sheet", the Esimple Premium Screen Protector is scratch and impact resistant. When you apply the cover you don't have to worry about it bubbling either. This is one of those odd habits I hate having but if a protective cover (for anything really) has bubbles, I will play with them for hours on end - yes I know weird. The plastic provides touch sensitive, crystal clear, HD protection
Available to purchase/Cost: $10.89 Esimple Premium Anti-Glare/Crystal Clear Screen Protector
Recommendation: I have to say at this price point it is a worthwhile purchase however, I wouldn't say it is anything stronger than the average screen protector. It is definitely a necessity for any phone let alone an iPhone though!
