Glass screen protector for FP5

I’ve already outlined my first impression of the Brotect protectors from schutzfolien24 bought via Ebay in the thread quoted above, but I’d like to add that now the protector easily gets air bubbles on the side when the phone is in a coat pocket (maybe the silicone case presses against it, since my pocket is small). Can be removed by pressing the bubbles to the side and away, but it’s still annoying. And I already did make the protector smaller by cutting its edges to be able to use it at all. Maybe I’ll cut the second one further…
