Review for the
Zagg Invisible Shield full body Easy Install
Price paid: $24.99
I had the Zagg Invisible Shield on my Touch Pro 2, and found that it was best for me to protect my new Epic 4G in the same manner.
The package came in a nice box with a protective flap to protect the shield from being creased. Also included was a microfiber cloth, a rubber squeegee, and a small spray bottle of installation solution. The presentation was very nice, and included instructions right on the package.
Clarity - Initially the Invisible Shield did not interfere with the SAMOLED display at all; The viewing angles were the same as naked. It wasn't until I started using the touch screen, getting my greezy finger oils all over the front did I start noticing color scattering and rainbow effects. So there is definitely more maintenance required to keeping the screen clear than just leaving it naked. Furthermore, the shield also leaves an "orange skin" texture that doesn't look smooth at all when the SAMOLED is off.
Form - From top to bottom, the skin fit perfectly, even leaving holes for the front camera, proximity sensors and LED. The only problem was that the shield was not as wide as the display, so there was a gap between the edge of the shield and the side edges. I reapplied the skin, stretching it a little to try and get the side edges covered more, but still didn't reach the edges completely. The shield for the rear of the phone covered the edge, and made it look darker and more "sparkly" than the rest of the plastic.
Ease of installation - The included spray solution and rubber squeegee made installing the Invisible Shield easy, but in order to really "slide" the protector into place (as per instructions), you have to really spray the shield down, which made me a little nervous about liquid damage. With the included squeegee, you can easily channel out the solution into an absorbent material like a cotton ball. Installation took me a few tries, but luckily the shield is durable enough to take it. Unfortunately, no matter what, I couldn't get some small bubbles to work themselves out, even after a few days.
Feel - Terrible. The Invisible Shield is rubbery, and not conducive to swiping and dragging at all; Because the surface is so rubbery, swiping may actually register as a series of taps, which is really annoying when trying to unlock with a pattern! I also noticed in a number of places where this interfered with multi-touch abilities, such as Pinch To Zoom. Testing with the multi-touch test program Dotty, I found that sometimes a lifted finger will continue registering a few moments afterwards, or that multiple finger presses would not register properly at all. This shield impairs device function which is unacceptable.
Maintenance - In order to avoid rainbow effects and scatters, you need to continually wipe down the surface of the phone. Otherwise the shield is fairly maintenance free. If it's anything like the one I had for the Touch Pro 2, the Invisible Shield is built to last.
Durability - Bulletproof. Invisible Shields take a licking and keep on ticking. I performed a key scratch test and it came away clean with just a small imperfection where the key stretched the material a little.
Overall Quality - This is a skin you'll want if you think you're going to subject your phone to some severe damage. You won't have much trouble getting this shield on your phone, but may have issues with bubbles that never work themselves out. Unfortunately, because of the extremely rubbery feel and the usability issues caused by it, I could not get "used" to this shield and took it off after less than a week of use.
