Zagg’s Invisible Shield Dry and Wrapsol Ultra are equally garbage. I would recommend you not waste your money on these products. Between difficulty applying the products to the iPhone 4S combined with the impossibility of removing air bubbles (even after waiting 24 hours), these products significantly degrade your visual experience on the iPhone 4S in exchange for protecting the screen from damage. I suppose if you like your Retina Display to look like a trippy mess, then these screen protectors might be something you would like to purchase.
