I was a huge fan of the InvisibleSHIELD for iPhone 3 series phones. When properly applied, they were awesome: crystal clear, completely stationary (no sliding, no peeling, no emerging bubbles), and shock resistant.
The iPhone 4 era InvisibleSHIELD, however, suffers from a serious manufacturing defect: roller lines. The machine rollers in their manufacturing process are leaving perfectly straight vertical lines on InvisibleSHIELDs coming off the line these days. You won't notice it at first; it will only become apparent once the shield has had 24 hours to dry and the bubbles have all disappeared.
You will then find perfectly straight, well-defined "rainbow lines" on the shield that refract light, particularly when your phone is showing a white screen. By holding the phone and shield up to light and turning them back and forth to see the protected screen at different angles, you will notice that there is a line running the length of the shield from rollers during manufacturing.
I have always applied InvisibleSHIELD protectors for family and friends and can do a perfect job each time and every time. This is not installation error; you can hold a ruler against the lines and see that they are perfectly straight and of precise width.
Of the six iPhone 4 protectors I've installed from Zagg, FOUR have had "rainbow lines" in them, one of them with TWO perfectly straight parallel "rainbow lines" running the length of the screen about a centimeter apart. (Search Google for the term "rainbow lines"; it's a well-known problem.) Zagg won't honor their lifetime warranty for affected protectors, instead saying it's a normal artifact of their manufacturing process (while some other reps will just tell you you've done a lousy job installing the protector).
So now it's "normal" for Zagg InvisibleSHIELD users to have prominent lines that look like screen defects running vertically across the screens of their iPhones. So much for "invisible."
In fact, they're extremely distracting and I'm currently looking for a similar wet-applied, soft-protector alternative that has better quality control.
Until Zagg acknowledges and fixes this quality control problem, I can't recommend dropping $20 on a product that will leave you wishing you could still read your pristine iPhone screen. It's a shame, because during the iPhone 3/3GS years this was the ULTIMATE in iPhone screen protection.
No longer. ZAGG invisibleSHIELD for Apple iPhone 4 (Front)
I sat here and read all of these negative reviews of using the ZAGG cover on the iPhone 4. Listen... if you go to Best Buy, purchase the product, have them install it, wait a few hours for it to settle, it works perfectly. I took my brand new iPhone 4 without even powering it up to Best Buy and had them install it. Also put a bumper from AT&T on it. Perfect match. I've had the entire phone covered for almost 3 months now, and not a single issue. Haven't had any peel up issues or even notice that it's on the phone. After install, it's a little "tacky" feel on your fingers on the touchscreen. After a few days after it's installed, I cannot even notice that there is a cover on it. Fingers move slick and perfectly without issue. The cover has actually saved my phone after I dropped it from several feet. It fell in a container of shredded lumber and nails. I pulled the phone out... the front and back were scratched terriblly.. After about 30 minutes... the scratches went away, and you couldn't tell that I had dropped the phone at all.. Totally recommend this product, I've also put it on my iPad, works wonderfully. Be sure to have someone install it for you to have it work like this. Any bubbles evaporate away in a few days... again... patience fools... ! These guys that describe the product as bad have no patience at all.... Good job ZAGG....
The protector is horrible for touchscreen. The surface is textured and sticky, the film is too thick and not clear. I removed it right away and replaced with cheap no-name one. Do not waste your time buying it.
Absolutely the worst screen protector I have ever used. It is difficult to move your finger across the screen, it feels like you have some sticky substance on the face of your phone. Perhaps with the iphone 4 one could use this on the back but on the front there are better ones out there. I would stay away from this product as it is very very over rated.
I tried this screen protector. I did not have any problems with the application. But the surface was not smooth with some kind of a texture. White pages on the screen looked with lot of refraction on the screen and was annoying. The worst part is none of these issues are covered under their so called lifetime warranty. Overall, it was an awful experience.
the Zagg invisiblesheild starts to peel from the edge after a few months of wear - you either have to deal with disgusting looking plastic on your phone or tear it off and get a new one - or go without. - Iphone 4 - Screen Protector - Iphone - Invisible Shield'
