I have always supersheilds screen protectors on my phones, today I dropped my brand new phone which had a tempered glass screen protector on it. I got lucky and my screen didn't break,. It I also discovered something. These are not tempered glass! The one that was on my phone pooped off (which is another issue altogether) and j accidentally stood on it afterwards (thanks goodness it wasn't my phone I stood on) but the protector didn't break!! If I stood on a regular tempered glass screen protector it would have definitely broken. I attached a video that shows just how far it would bend. Now I have been using screen protectors from my friends supersheilds for a long time I have used them on all but 1 phone I have ever had and that have saved my phone many times. I don't know if I just got a defective one or not but I feel that is is important that you know this, maybe it was just that something slipped through QA but I don't think so because I tried it on the second one that I got and it did break but only after it flexed almost 180 degrees!!! My phone screen will definitely break before the protector breaks.
