ok. I have install invis shield for mine. U really need alot of patience n have to do it slowly. I suck up for my front bcoz not used to it but my back is nice. U need some practice to get it right however my back is npw very safe. Bcoz when put it in yr pocket, it might get scratches, coz might hv small stones which we cant see with our naked eyes

Without Invis shieild, chances of getting scratches is high. AFter installing, i have tried n confirm totally protected. feel so safe now. Emm...planning to buy another CoZip case so after try let u know. I trying scratching with car key. the case is ok but the shield got some scratches there. thei shield wun break
