I ordered 2 of these one for my daughter and one for myself. They arrived in good time and in new condition.
I took the old one out and replaced it with this one. The color is slightly darker than apple but that didn't bother me as it is not seen. I plugged it in for a night and let it have a full charge. I then unhooked power cord and just used battery and was a bit disappointed with the time it lasted about an 1hour 40 min. I was just surfing Internet.
It was cheaper than apple don't think it lasts as long as original did when it was new. But battery fits good so no real complaints because I can now have it unplugged for a period of time if I need to.
