These screen protectors were very cheap so I was not sure that they would work. They came individually packaged and each protector was in 3 layers: adhesive protection layer (labeled Step 1), the protector and finally a top protection layer (labeled Step 2). Following the directions, I cleaned the screen and then partially removed Step 1 while aligning and slowly laying the "sticky side" down on the screen. But it would not lay flat so that the bubbles could be removed (as directions indicate). I checked the so-called sticky side and found that there was NO adhesive! I was very unhappy! On a whim, I removed Side 2 and then SURPRISE - the protector adhered itself perfectly well to the screen. SO BE AWARE OF THIS!
Compared to Expensive Screen Protectors I also tried REALOOK Samsung Galaxy Note Screen Protector, Crystal Clear 2-PK. COST: Realook was FAR, FAR more expensive, and only had only 2 protectors. ADHESIVE: Realook has a more sticky adhesive, but actually did not stick better. DIRT and BUBBLES: The stickier adhesive on Realook attracted more dirt and made it harder to apply DURABILITY: Both have identical hard surface suitable for a stylus REFLECTIONS: Both are clear non matte, so reflections do occur FINGERPRINTS: Both are fingerprint magnets.
