Query: Not durable

They protected my phone screen like they were supposed to. However, the first screen protector cracked after 2 days of regular use. I was hesitant to put the second protector on because it came with a bubble in it. After the protector cracked more and more I had to. I just put it on and so far it is fine other than the bubble I couldn't get out at the top of the screen
