Very easy to install and it does not interfere with finger touch screens at all. You cannot even tell that it's on your phone. It claims that it has a lifetime warranty however and I'm now on the third one for the same phone. I know why they sent three in a pack! Is each of the first two screens cracked they did indeed protect the original screen which did not crack. I do have some faint underlying vertical discolorations in my phone screen now which means that some at least mild damage to the inside of the phone occurred. I often allow my grandkids to use my phone to watch videos and such so it may be exposed to a little bit rougher treatment than some phones get. It did indeed keep my screen from cracking which is great. I found taking the cracked cover off was not real difficult and putting the new one on is very easy and it's great to lineup. I think overall it's a pretty good product and I would indeed buy it again. I think their claim to add having a lifetime warranty is probably at least a little bit blown up. Again there's a reason they send you three of them in one package. It did take me a little over a year to go through the first two though
