Tempered glass resist hits especially from blunt/objects far better than normal glass for most parts.just worried the occasional bouncy ball launching off of it might have been cause for concern
Also same for resistance against fine scratches.
Though after certain limit is reached, internal tension blows whole glass at once instead of you having one scratch.
But what you have to be really carefull is the fact that edges and corners are super vulnerable compared to normal glass:
Even slight touch to some rough concrete/stone can nick surface enough to trigger tensions to blow up that glass.
