Easy to follow instructions glass cover seems top stuff so far centering the panel on the screen is no easy task and had to nail remove and apply once again for about 4 times until got it right

Its a great product for z2 i bought this as a replacement for another brand of tempered glass which broke after a year i switched because i read so many good reviews about this product and i was not disappointed instructions are super clear comes with alcohol cleaning wipe and a microfiber as well for you to remove any dust from the phone

I got the matte phone screen protector the directions were easy to follow the screen protector was very easy for me to apply and i had no issues with air bubbles at all surprisingly

I just had some dust under the screen but the dust removing stickers provided in the package were helpful
