I am very drop prone. Like, I could sneeze and my phone will somehow eject itself from my pocket to smash on concrete. I have now replaced my screen protector twice (which is saying nothing against how durable these protectors are, because with how much I drop my phone, only needing two replacements in two years is a miracle). Each replacement has broken only the screen cover and left my phone screen spotless.
The first time I filled out the form for a replacement, I had been wondering whether it would end up being too good to be true, and there’d be a small caveat saying “lifetime warranty unless breaks are your own fault because you're an idiot that drops your phone.” Thankfully, that was not my experience. The customer care people were SO nice (we love Jinger!). They’re super quick in their replies, and everything got taken care of easily. I paid shipping and had my spanking new replacement in no time.
As for the screen protector itself (other than being awesome at not breaking), it's great. I had been worried the screen would be too dark to see through, but that’s not the case. It did take some getting used to at first, but I adjusted and now never have to keep my screen brightness high. I barely ever have it even halfway bright.
As for how private it is? Extremely. I actually had a friend ask why I was tapping on my phone when it was turned off. It’s almost frustrating at times because I’ll want to quickly show someone a picture and I have to make sure they’re properly positioned to see the screen. It works.
