Review on MacBook Air 13 Inch Tempered Glass Screen Protector for Model A1369 A1466 with Large Cleaning Cloth - Bubble Free, Not Compatible with Newest Mac Air 13 A1932 by Jason Nguyen

Screen protectors take a little learning to do - they don't adhere instantly, it usually takes a while for them to fully adhere. As long as you don't have big blisters, that's fine - just leave it on, it will stick by itself! Fits perfectly, the packaging of this product was great - very secure to avoid damage. The instructions are pretty clear and understandable, but then again, with glass covers (as opposed to plastic ones), it can be a bit disconcerting to see large portions of the screen where the screen protector isn't fully adhered. Only remove it if dust has accumulated underneath. If it's just air, gently push it out and help it move forward.
