Not bad at all, my FP5 has been rock solid

At the begining the bluetooth was a bit week, but that has since disappeared.

maybe I am just not super strict about those things. There is indeed a 1 mm gap between the screen protector and the bezel, but for me it is good enough.

I also have a clear TPU cover around the phone, I reckon it is very unlikely it will get damaged or scratched

You can find a few brands on amazon, I got a brotech anti-reflection protector for my FP5
