I use this on my treo, mp3 player and even wide screen nuvi 650 nav system. These screen protectors are even better than the old ones, because the backing has measured grid lines that help you cut out the precsise size that you need for your screen. I've had no trouble removing these from any screens. The screens are also nice and clear to see through. I has saved me many times when I stick my keys into the same pocket as one of my electronics.
