Review

Mobile electronics like smartphones and tablets are great, but it doesn’t matter who makes them, they all share one weak spot: the display. That big, bright screen is prone to scratches and with touch operation, it’s a magnet for fingerprints. Annoying as they are, the smudges can at least be cleaned off, but once your display is scratched, it’s scratched. The only real option you have is to replace it —and that is an expensive proposition. The ZAGG Invisible Shield Glass is an ultrathin slab of tempered glass you apply on top of your display for complete protection against scratches and resistance to fingerprints. I tested out versions for the iPad Mini with Retina Display and iPad Air and ZAGG Invisible Shield Glass is now on my must-have list for future device purchases.
