Wasn't charging unless I crammed the converter cable into the MagSafe DC-In board, which was not always reliable and made my fingers sore!
Without a hitch! The part arrived extremely quickly (much faster than the AC converter cable I ordered from somewhere else). The repair was easy and efficient due to the wonderful illustrated instructions from ifixit!
Be extremely careful of the little fingers gripping the I/O board; they are fragile and on my book, two were folded to ensure a good grip. I tore one.
