I've installed it on 3 of my kayaks, and installed for several friends. It's not perfect, but pretty good stuff. It can be cut by hitting something really sharp, but that would have done things to the kayak with the strip not there to take the punishment.
I use a heat gun to warm it up well when applying. At the stern of most boats, the angle is too great to apply without puckering. I make a cut on each side at the pucker and overlap the tape so it's flat. Then I cut out a dart (a V-shaped piece) where the tape overlaps itself. I do this so the tape will lay flat with no overlap after the piece is removed. I paint over the cut with Aquaseal or Marine Goop to further seal it.
Done like this, I think it would be hard to pick up invasives. To be sure, washing down the boat with a hose is always a good idea.
Full disclosure - I became an official installer for KeelEazy. I find that a 2-3 foot piece at bow and stern will protect a boat from most incidents, and saves some money. If you don't mind the cost, a full strip will take some wear off the center keel line.
