"So long, air bubbles. When we heard about a fool-proof screen protector kit for the iPhone \u2014 with promises that even those with the clumsiest of hands could magically glide the sticky coating onto devices with ease \u2014 we had to give it a try.\nThe PureTek Roll-On Screen Shield Kit kit by Pure Gear ($24.99) aims to make the process of adding a screen protector to mobile devices seamless, eliminating the hassle of ironing out air bubbles and lining the shield perfectly over a smartphone. The kit's packaging serves as an application tray that lines both iPhone 4 and iPhone 4S devices up to the 0.22 mm ultra-thin shield.\nBy dropping an iPhone into the application tray and using the roller included in the kit, users slide the protector over the smartphone and work out the air bubbles for a clean, sleek and protected display.\nThe concept in itself is brilliant \u2014 why didn't someone think of this before? However, we experienced a few small kinks along the way. Although the protective shield is hardly visible over the touchscreen, the cover doesn't completely align with our home screen button. In addition, a few small air bubbles and smudges appeared near the top of the device. We had been told that these  dissipate in 24 hours, and that's exactly what happened. However, a smudge left by fingerprints under the stickiness still remain in the top corner. It's largely concealed by the iPhone's cover though.\nFor those with attention to detail, these quirks might be bothersome. But overall, the PureTek kit is an impressive and effortless way to get to take the sticky factor out of ensuring your iPhone's screen protection.\nWhat do you think of screen protectors? Are they worth it or too frustrating? Let us know your thoughts in the comments.\nUPDATE: This story was updated from it's original version to reflect what happened to the air bubbles 24 hours later."^^<http://www.w3.org/2001/XMLSchema#string>
