these clear skins were being made
before invisible shield got so popular, i don't think anyone is ripping them off... besides the invisible shields key selling point is the material it's made of, not the concept of a thin clear iPod covering.
I have the martin fields protector for both my nano and my iPod. Love them. very clear and very smooth. almost can't tell it's there... my only wish is that the back one cover more of the surface... but i never had protection on th eback of my 1G and 3G iPods... they were still scratch free...
I like the invisible shield, but seems like a hassle to get on an right compared to the fields sheets.
