My bubbles are at the top, but I use WriteShields.
They sent me a little probe in my protector kit that could lift up the edges but the bubbles really don't bother me.
I'll take a picture when I'm at a PC tomorrow
Surprisingly, not a dust mote in my application but I did have to use one protector to figure out how and when to remove the film.
Heck it took me a while to realize there was a protective film
