I too am trying to find a good, well received Privacy screen protector that supports the fingerprint scanner. So far pickings are quite slim.
I had bought this one in haste, only to have a pretty bad experience with it.
I took it off after only 18 hours of putting it on. Viewing at extreme angles is still possible, touch sensitivity is pretty bad around the edges, fingerprint scanner is completely unusable.
Just avoid this one.
I have actually been actively searching for a good one on Amazon and other sites.
I will report back when I find one that works.
