Mine arrived and I have installed it. As thick as this thing is, I don't see how it could get air bubbles, but just in case, I cut five 1/4" notches out of the tape: one on all four corners and another in the middle (the side without the overlap).
There were some very tiny patches of air bubbles in the plastic that keep it from being perfectly smooth in some areas, but it wasn't bad enough that I'm willing to go through sending it back. Apparently this is the only company that makes these, so I'd rather have it than not have anything at all.
My kids dragged two bicycles out of the back of my two-week-old Explorer and gashed the back bumper in a few places, so this was something I really needed. Paint job on the bumper was going to run $360 - $470, depending on who did it, so this was a much better alternative.
EDIT: I just noticed that I'm showing only two posts at this site, but I have posted here off-and-on since joining three years ago. ???
