I used to use Zagg and BSE before and I remember it having a distinctive rubbery feel. Anyway, I purchased the Spigen front and back since it was readily available on Amazon but the sides were still exposed and may be damaged from paint chipping.
I've had sticker boy.net products before on 4/4S and they now have a clear one. Purchased a clear front, matte back and sides and they did a combination of dry and wet application. Both can work - depends on how well you install it. Anyway, it looks a lot better now. The Spigen had a lot of scratches after Day 1 and this one still looks goes great days after. No "rubbery/sticky" feeling at all; just feels like how it was without the skins on it. It's not much, but using code: CABLE gets you 5% off.
