It broke very easy the, less than 1 week after putting it on. I rarely drop my phone, but it fell one time off of my desk at work and the screen protector cracked completely. Thankfully my phone screen is ok.
Online it stated that it was easy; however, getting the "bubbles" out was not so easy. I almost gave up. Would have paid for professional installation if I would have had that choice. Glad though that there is a warranty.
It seems fine. Went on easily-- good instructions and tools to help it be a successful installation :-) No problems. I always install a screen protector and it has saved my phone more than once.
