Review on ZAGG InvisibleShield GlassFusion Protector Friendly by Bill Snyder

Perhaps the worst thing about this product is the false advertising. Let me be clear that this is a POLYMER FILM screen protector. Every marketing and presentation element indicates that it has solid glass elements. Do not be fooled. It is a FILM only and does not protect against shocks. Just scratches. Secondly. Two of the three I received were mislabeled and for a completely different phone. (I ordered for the S21 Ultra and got the regular S21 instead. TWICE!). From what I received which was actually for my phone I will put aside the fact that one corner of it was damaged right out of the box and just focus on the quality. It was the perfect setup. No dust particles, no bubbles. BUT. just one day later the corners started to bubble. If you press it, the bubbles will go away, but only for a few hours. Total: from unscrupulous advertising to poor quality. This is a complete waste of money.
