Hab three sheets tested in the last few days: a cheap Nilkin, an expensive tempered glass of Case Base and ultimately it here. The winner is clearly this film. The Case Base foil or glass could be due to small bumps on the glass (the normal in such a production are) applying little bubbles, after some time they broke even partially and that's why I could not imagine that these survive the long-term test. The Nilkin was indeed easy to install, but as almost always is the case with a clear film, it was a magnet for smudges and fingerprints. This film of slabo is super. It feels good as paper takes, reflections and fingerprints can be seen barely. In addition, the OnePlus can now read in the sun. The best is of course the price. It is worth every penny.
