I know this sounds like a corny advert but I recently bought the phantom skinz for my droid. I have always covered my gadgets with zagg invishield and until recently wasn't aware of the alternatives.
Well the phantom skinz are cheaper well you get 2x for your money). They don't come in a fancy package or with any application solution "water with a drop of soap". They do come with an "applicator" otherwise known as a blank credit card with an advert on it.
There were a number of small pieces to cover everything and I really took my time doing it. I have always managed ok more or less with the zagg shields and hoped this would not be any harder.
I followed the instructions, took the battery out and after an hour or so had everything put on. I waited a couple of hours for everything to dry. I hoped that I had everything clean and smudge free at this point!
The result after a couple of days was great. Better than the zagg I felt. There is noticabley less of the orange peel effect, touch sensitivity is just the same. It is not quite as non slip as the zagg but that is good on the screen itself. Sure the back plate goes from being rubbery matte to shiny but I can live with that. The back face of the phone is an ugly mess anyway I think.
All in all highly recommend and probably better than the zagg I would say.
