My wife and I both have the same phone models and we were using the same screen protectors that originally came with the phones 2 years ago. As they were scuffed with the years, we decided to refresh them. What an error it proved to be. This new glass protector on my phone cracked from one side to the other within less then 24hours and my wife's chipped on the edge within a few hours! Proceeded to change my with the last protector in the pack,2 days later and its now cracked again! This is not serious! Bad quality! Completely useless! Should have kept our old used screen protectors that were still good and uncracked!
