Query: 2nd one works fine - and great Amazon customer service

Received the first unit and it had the mechanical defect of the DVD draw not opening. Emailed Amazon customer service, received reply within 24 hours that a 2nd unit was being shipped, and that UPS would pick up the defective one. Received the second one same day the first was picked up. Free shipping all the way around. 2nd unit works fine. Good value for these features. Will see if the DVD draw holds up. Problem with the first one sounded like an alignment issue.
