I got these after my Rhinoshield one cracked. Super simple.to install. Doesn't affect touch sensitivity. And super low price. Def see why they have such high ratings.
There are two that work fine that are cheap for the Note 8 which if you search here you will see are recommended. I have this one below and it works great. No loss of sensitivity. Does pick up fingerprints though.
