Here at Ameego we provide the best in market tempered glass. Our tempered glass adds a layer of protection over your screen without making an obstruction. With specific cut-outs for your speaker grill the tempered glass does not reduce functionality. Behind the glass is a piece of film which makes it shatter resistant. This works because when the glass breaks, the film doesn't allow the glass to separate. This prevents the glass from shattering everywhere, prevents the glass making a mess and even prevents the broken glass becoming quite dangerous. Remember the tempered glass protects your phone most of the time but damage can still get through with hard drops.
