So I just had mine applied, and it's obviously still drying. But, I have to say...
This looks like garbage-ass, in any amount of light.
The material has all kinds of bumps and imperfections on the surface that show up in the slightest amount of light. They didn't have the kits, so the dude did a notoriously bad job on a custom cut. There are pen marks all over the window tint material, and the cuts are not even, so the entire surface of the phone is not covered. Brilliant.
Dude rush-jobbed it in like 5 minutes, and was busy douching it up with a bunch of other customers, or else I would've just told him to re-do it.
It strikes me that standing up at a mall kiosk is probably not the best place to perform delicate work on smartphones.
Anyway, he told me the custom-cut kits for the myTouch 4G come next week, and then I can get my replacement for free. I plan on doing that. I asked him multiple times about that 'for free' thing, and he assured me that they don't charge for custom cuts while you wait for the kit.
So, we'll see. As it dries, it looks like someone rubbed oil all over the glass. That will change as the liquid evaporates, but to say that the material is 'crystal clear' (as they do) is a bit disingenuous.
The ****ty T-Mobile skins don't cover the whole front of the phone, and they scratch easily. They are super over-priced. That said, at least they are smooth as glass. Ghost Armor - at least when custom-cut by some dingus - looks like a bad window tinting job when the screen isn't on.
Update:
I don't think the dude properly lubricated the squeegee, nor did he clean or watch out for debris. My screen has a bunch of bubbles, and some spots look like they were stabbed with a ballpoint pen. Lame.
Besides the amateur hour rush job, I dislike how rubberized the screen becomes. If ever there were multitouch games, I could easily see them being unplayable, due to finger friction. But I guess that's the nature of the beast.
