I acquired from Cockpit Simulator the CS 737X MCP equipment, I want to express here, the experience I had in relation to the product and the service provided by the Company. Everything is of excellent quality. I had a slight problem with the VERT SPEED display. The problem was reported through an email to the company and within 10 days I received a new equipment and a label for returning the defective equipment. Everything went very fast and no questions asked. I am happy with this purchase.
