The entire iPhone 4s is covered in glass, so why-oh-why would you use one of those horrible screen protectors that is anything but?
The GLAS.t screen protector is crafted entirely from tempered glass and won’t scratch, even when held at knife point (or key point if you catch our drift). Technically it’s three times stronger than those other screen protectors, yet is just .4mm thick. The glass has been chemically tempered which means when and if you manage to break it, the GLAS.t won’t shatter into sharp pieces and cut your femoral artery open (that’s the one in your leg, next to your pant pocket). And for those of you that just ooze butter from you pores, there is good news; it sports an Oleophobic coating, which is said to prevent fingerprints and other contaminants, making it extra easy to clean, though we’ve never had trouble wiping the iPhone’s screen to its original resilience.
The GLAS.t installs using a built-in adhesive. As a result, they don’t recommend repurposing the glass screen protector as the adhesive may lessen after the first application. That said, you may want to be sure what iPhone you plan on installing the GLAS.t to as it costs $28 a pop.
