The v-screen is a lot of fun. It does what it advertises-- on some games, anyway. When it does work, The 3d effect is amazing, but it is mostly noticable on racing games, which are what I like to play. It does increase the screen size of the psp as well, I'd guess it makes the screen appear to be somewhere around 6 inches big. It acts as a travel case and protects the psp screen. It is a bit bulky, but it still fits in my pocket. Overall I'd give it close to a ten. I would never want to go back to viewing the psp the old way!
