Those who do not get along with the instructions and often has bubbles under the film, should google times for tips and possibly watch instructional videos. With a little practice you get it back.
Will continue to buy the product, use a film ever 4-6 months.
Since my phone is in constant use, and I do not often get to, clean the screen, he sees accordingly after half a year of + many scratches, but you do not see at first glance. I pull the film off, I felt a brand new cell phone without a scratch in my hand - Could not be better!
Would recommend it to anyone who has the Z.
