tablet cover challenged

Ugh, I feel like I need a degree to put on a new cover for my tablet so I don’t have any smudges. Two of the last three skins that I bought made me feel retarded. I had to turn it off completely, recruit my husband to help me, watch a video, wash my hands, spray a liquid that they provided me to put it on to my tablet and then squeegee it on. Only to do it incorrectly and have to buy another one that proved to be just as difficult (although it did come out a little better). I have finally given up and will be getting my moshi cover from AT&T. So far it has made me the happiest, but if it comes with a squeegee and spray bottle of liquid I’m going to shoot myself.
