The positives: the cut is snug, and when asked, the glass is easily forgotten. It leaves a very good visibility, cleans glass as the original and has nothing to do with the plastic films that end up getting scratched so we wonder why we have a retina display below. Installation is relatively simple, but it is better not to try twice as dust particles adhere under the glass. That said, once installed carefully it is not unsightly bubble; but if you have to remove it to reposition it, it's less obvious. The bad: the package (neat) does not book cleaners or adhesive for removing dust or the latest application card or booster button (contrary to what other manufacturers are doing).
