These screen-protectors are a waste of money. When they arrived the packaging was good, instructions clear then I realised that there was dirt or cloth-like fibres on the screen protector before they were even opened. I thought maybe it was just on the removable slips so I proceeded to apply them but behold its impossible to apply these properly as the fibres were indeed on the screen protector inside the removable films. I applied both with the same result, the screen will have air bubbles and or cloth-like fibres on the screen (which is very annoying). I would never recommend using Subsonic screen protectors, do not be fooled by the price, go for a more expensive brand as you are basically throwing your money away on this brand.
