I like mine, a lot
I have on on my ipod that I guess I gave to my four-year-old. It's tough stuff.
I think it sounds wacko, but I am convinced the skin absorbs a little of the impact of a drop. It really is scratch proof, and if you put them on right, it should cover all of the unit except of the corners of the battery cover &($11 on ebay). It's 3D curved, so there really isn't a way to engineer it perfectly. I took my glasses off (hard core near sighted) and dabbed a bit of fingernail top coat in the cracks to match the sheen and protect a little. It hasn't chipped or peeled in the tiny cracks that were left.
Yes, eventually they do peel up, particularly if you're sliding it in & out of another really tight case, but even so, they stay put pretty well despite a corner or two coming up. If it's intsalled correctly and there are no regular spots where it's worn really hard, I can't imagine anything peeling up unless you pick at it.
I put mine on myself, entirely sober and well-slept. I was really concerned about the job I did at first, but the skin settles into place after a day or two. Now it looks pretty good (i.e. I'm happy with it, so it's notably invisible to other people).
I like the "StickyPad" effect it has, particularly on the back, but it's handy on the front for when I have it face down (I like Face of Ring in market). It's very rubbery, so it doesn't slide around on a desk, nightstand or dashboard, and with foam on car mounts, etc. it really stays put.
If anything, I would get a screen protector from another manufacturer that isn't so glossy. It has a bit of a wavy texture if you look closely, so on the screen it looks a little odd if you're thinking about it, and looking at it. A slippery screen for finger gestures makes more sense, but I'm leaving mine in place becuase I know it's rock solid screen protection (and it's cut to fit the rest of the skin).
I'm looking forward to putting on my next one because I know it'll turn out better. I'll put the screen protector on first, then line up the surrounding screen-edge side peices to match it at the top and the bottom of the screen, so that then I can line up the top-edge and bottom edge pieces with a straight line from the screen side & corners, rather than the bottom edge of the screen assembly. The rest was really straightforward, tedious, and not for people who don't have a knack for fine motor movement and estimating sall measurements fairly acurately. But I can't even pay someone to replace my brake pads, much less put on a phone protector.
And what that other guy said: REALLY, REALLY WET. I think I'll be more liberal with the spray next time. You can slide it around for about a second without stretching it. If you have a lint free towel, it handy for keeping the spray out of the unit but still have enough to slide around until it's right.
I had trouble with the corner opposite the camera button. The phone curves in the back, and the dart (the v-shaped cut to make the corner) wasn't quite deep enough, so I used Swiss Army knife scissors and trimmed the extra that just wouldn't stick down because it was just too much. I'm glad I did.
I know there's lint under my screen protector, but I can't see it. The bubbles, if they're tiny, just seem to disappear. It's really a cool material, and worth a try just to see the stuff.
Besides, it fits inside another case.
