Received product quickly to very light postage. The cut matches the gsm. The installation requires some skill and precision, but is not difficult. I do not know how long protection is still usable and enjoyable to use. But I guess with 6 guards I have at least several months and for a price almost 6 times less than 2 universal coverage (which must then cut himself on a template available on the Internet) sold store in Belgium where there is not the protections for Wiko. The protection is very transparent. I do not see the screen brightness difference with and without protection. In short, I am very satisfied with these protections.
