Summary: Easy to use, just snap it on and protect your LCD from chips and scratches. The negative is that it also scatches very easily and at ten dollars a pop can get costly. You decide, new LCD or a new cover.
Summary: I bought one as a replacement for the cover that came with the camera. It provides protection against scratches and nose smudges. However, it's a bit fragile -- the plastic flanges that keep it attached to the camera body can snap off easily.
Summary: Cheap simple protection. Snaps on for a perfect fit. When it's on it doesn't degrade the picture any. If you ever want to sell your camera this will ensure you get top dollar-nobody wants a camera with a scratched LCD screen!
