I got a Spigen thrown in for free when I bought my Samsung s9 plus at Costco years ago. I was very cynical about it at first because I was just a screen protector user prior.

I now have a Spigen for my newer phones, I am a Spigen customer for life. These things are legit. They somehow protect the front as well and I don't know how.
