I bought this item after my laptop broke. All the reviews said it was great, read through all the information, and bought it in “excellent condition”. Well, it was NOT in excellent condition. Right away I could see dents and scratches on all four corners, there was left over glue residue inside, and I had multiple screws in the bottom of the laptop. The battery went from 50% to 6% in less that 30 minutes of using it, and as soon as I got it I told me I needed to take it into an Apple store to replace the battery which costs $300. On top of that when I called to order a replacement/ refund they were rude and did not listen to my complaints. This is by far the WORST product I have ever bought from Amazon! If I could give it 0 stars I would.
