Sound cutting out in the right earbud. Bad enough to have consistently left only sound, but sometimes it gave that static-y KSSH sound, which is really annoying.
Pretty well. The guides were excellent, the part was perfect, no problems there. But did take several tries to get it right.
Battery connection is HARD! Took about three tries to get the little connector in its slot. That could be covered a little better.
If you get a message like "Low power - charging" with the USB plugged in, check this connector. It really has to be pushed down in there. You might need a tool, but go easy.
