Query: A Nice Addition

The grips really make holding the PSP a lot easier, and they don't add as much bulk as other grips (they even fold in, for when you're not playing). However, they do not reduce glare greatly, although it's near impossible to play the PSP outdoors in the sun anyways, and the screen scratches way too easily. The scratches also reflect in certain lighting, which actually increases glare. Ultimately, the grips still serve their purpose, and it is probably possible to buff out the scratches and then put a protective cover, such as the Martin Fields PSP Screen Protector, on top of the case.
