I just received and it seems fine. I purchased on the basis of the comments here and I am not sorry. The battery arrives with no instructions for calibrating, so if you need that you’ll need to look on the internet. My first charge calculated to more than four hours. So far, so good.
Product was shipped on a timely basis. Despite USPS issues, I was able to receive my battery after it had to be re-shipped. Seller went the extra mile for me to get my order.
The battery works great, but the only reason i did not give it 5 stars was due to the fact that it can only hold a 4 hour charge. 4 hours is great, but the original apple battery would hold about 5 hours and change. Overall the battery is worth the price compared to apples absurd price. Its a battery so its lifespan will slowly diminish.
