I am giving this 4 stars because it has nothing to do with the seller. The computer was indeed in excellent condition and they shipped it in one day! The seller deserves 200 stars. However the product could not stay charged for more than 2 hours. This is more on Apple not the seller. The seller did great but the manufacturer did not so that’s why I gave 4 stars. I have returned it and ordered the 2020 version with M1 chip and it was actually less money. So let’s hope it has better battery life.
