Zagg covers have their limitations.
Let me add; I have had zagg covers on my iPhone for a few years. I have installed them with much care. The large flat segments that cover the front tend to last longer. The smaller sections that wrap around corners etc. peel off fairly quickly and you have to cut them off. The covers do protect the front fairly well. Eventually -within 6-8 months the corners of the front cover do begin to turn brown and you have to trim those off. I have decided not to purchase a Zagg cover for my new iPad2.
