GameDr One Case of Four Pieces Sony Motorized UMD Cartridge Cleaner for Sony PSP - Playstation Portable

Bought brand new, but it did not work. Took it apart and had to move a gear and get it set right to spin the disc. On top of the the battery housing is so flimsy the batteries pop out on their own so had to super glue them in place. All in all, horrible cheap design, do not buy.
