Pros: They do what they're meant to do, that is protect dust from collecting in the port of my PSP. They're easy to put on, especially the one for the power cord. The white colour goes well with my black PSP.

Cons: They're hard to remove, particularly the usb cap. I had to take it off slowly, or I'll end up cracking the psp plastic casing. The headphones does have a tab for easier removal, but it gets it my way when I'm playing.

Other Thoughts: All the caps come with pair, except for the usb one. It would have been nice if there was another one for backup. Also, I haven't been able to figure out how to use the joypad covers. There's tape on the other side, so I guess I'm supposed to tape them onto the joypad?! Well, whatever the case I didn't need them anyways.

Bottomline: The price was not cheap, but fair. And they are useful since it's easy to get dust in those ports. Plus I can't find anything else that does the same thing. I'll just have to careful every time I remove the usb cap.
