I ordered this item for changing an optical block KEM-450DAA on a PS3 slim model CECH2504A and I expect to receive a compatible product, but no, it is a complete block and nine model: KEM-450DAA! very well packaged (double protection bubble cardboard more!) the little extra is the Torx screwdriver to disassemble the console! very well thought out, because I have not struggled by not having to dismantle ;-)
the console is still left to hope for numerous hours! my nephew was delighted, desperate that he could no longer play ! for block assembly, there are many tutorial videos on youtube and on the web! it only took me 20 min winding barely understood! again this is much cheaper than other site! I therefore recommend to repair a ps3 slim ;-)
