I have brought the system due to the many positive reviews, not really a really negative. When searching, I really got me properly time left after I had a serious blunder in retail with a Philips Micro system (from unfriendly sellers, lousy customer service, etc. in the company Expert I do not want to continue to delve) I had only Yamaha because the eye I have a Yamaha conditioning in the living room, however, startled me the rather poor product support from Yamaha (my just 3 1/2 year old "High End BluRay player does not play current 3D BluRays off and there is no firmware update!) and quite a few negative . Judgments With Panasonic I connect from my own experience since 1989 good support unjd especially quality (use seitem TV devices, DVD / BluRay player and a microwave from the house of Panasonic) - never a defect (since my brother and my sister countless problems . had with Philips TV's) I do not want to give the impression of Panasonic to operate product advertising, is just my experience a downer and thereby a star deduction is there for me yet. The front USB is exclusively reserved Apple devices and does not support conventional MP3 USB sticks.
