Zagg seems to be getting some bad reviews on this forum. I bought it the day I ordered my Vibrant and installed it the day I received it. Back looks awesome, and it is not nearly as slippery as the back cover alone. Front however.... zagg is slightly narrower than the screen, and it is bugging me. Also, it is far from invisible on the front, but I guess I will live with it rather than having my screen scratched. What really sucks is that the "full body cover" does NOT cover the corners nor the bezel, and we know what happens to these phones if you drop them.
I will have my case soon, as I planned - I put the zagg on so my phone does not get scratched with the particles that get under the case. Once I have the case on, I will feel a bit more comfortable handling the phone.
