content: I purchased this product for the dual use. The DVD on this unit never worked and when i called the customer service they wanted me to send it back to them and were going to charge me $160 to replace it with the newer version. I asked what would they do if the DVD does not function in the new unit and they did not had an answer to that. This company does not stand by its product. DO NOT MAKE A MISTAKE OF BUYING THIS PRODUCT AT ANY COST!
