I read the reviews and took my Mac laptop to have the keyboard repaired. Just picked it up and discovered they installed a very used and worn keyboard on the computer. The replacement keyboard did not sit properly on the lower unit and was scratched and cracked along the edges. I was very disappointed with the results. When I asked about the warranty, I was instructed to read the bottom of the invoice for information. I will not be using this business in the future nor will recommend them to others.
