Excellent, the best product I've tested to protect the screen of the compact Z1

Excellent product. The glass film is oleophobic, fingerprints are almost insibles, nothing to do with a plastic film! the result is just ... stunning: we see nothing :-)
Everything you need is provided in the box (solid): cleaning alcohol wipe, microfiber cleaning cloth, instructions and of course the film, in a case.
I do not advise the use of microfiber to clean BEFORE putting the protection screen. After, OK.
Once the screen cleaned with the wipe alcolisée, protection is removed from the glass screen and at-dessu we place the device then supports the center for the plating on the screen. Magic, it adheres like oil spread and then ... perfect.
The difficulty lies in cleaning, but the alcohol wipe the job done perfectly (no dust) and then the vertical timing (to aim well, me, it is imperceptibly wrong, but it's almost perfect)
