Rating: 5/5 Excellent December 23, 2019 I had bought another battery from another company. It was cheaper than this one but when it arrived, it didn't fit properly so I had to return it. This one came and I could tell that it was of superior quality. Even the packaging was superior. The best thing are the very clear and specific installation videos. These are worth any extra cost and I commend MacSales for their thoroughness and beautiful and simple video presentation. I've only had great success with OWC and MacSales and won't deal with any else anymore.

Rating: 5/5 Excellent replacement battery for MacBook Air February 11, 2016 After almost five years it was time to replace my 11 in MacBook Air battery. The cost from OWC was less than half what Apple charges for replacing the OEM battery. All the necessary instructions and tools are sent with the product and the replacement process is literally a 15-minute job even if you have minimal skills in such things.

The quality of the battery appears to be equivalent to the original it replaced. I needed some customer support due to a mistake I made when installing the battery. Once corrected there was no longer a problem and the response I received from OWC was outstanding.

I would recommend this item to a friend!
