When I ask protections screens I always put myself in my bathroom with hot running water and a lot of vapors that dust is not present in the air. Good for what protects screen I kinda miss my shot and I had to take me to three times (and thus manipulate the screen too many times), final result I the lower right edge (in the egg black screen) that glue more but that's my fault and it does not change, the protection does not move anyway, so this is purely aesthetic. All that to say that the quality is there because even after handling the product still fits well, from the time it is neither broken nor scratch (well I have not done either of crash test say it). Considering the price, I recommend it.
