Invisible shield really SUCKS. Scratches very easily, very cheaply made, and very expensive to replace. After I spent $65 for the 1st shield, which lasted only one day, they charged me another $10 for the 'free' replacement. You're better off buying a roll of clear packing tape for $3. I've been using that for decades to protect glass. Or buy a real glass protector for $10 online. AVOID ZAGG! They have the WORST reviews for a reason.
