Customers most agreed on the following attributes:
I didn't use the one that came with my camera at first but fast learned that it was not a good thing to do. This is something that offers great protection to your camera
What more can a piece of clear plastic do? It protects the LCD screen from dust, sand, dirt, and scratches. One issue (and it's probably my fault): when I hold the camera in the vertical position, I end up breathing on the cover and it fogs up both the cover and the LCD screen. Takes a while to clear out since the screen protector has such a close fit.
Does a good job protecting LCD. Clicks on securely but can, on rare occasion, pop out with rough camera use. I have also used PDA protective film on my D70's LCD.
