Query: Not Reliable

I bought this model right after it was available in Dec last year. Initially it worded great. But after only two months, all the audio inputs do not work. I have to pay for the shipping for the exchange under the warranty. One more thing I like to point out. AM/FM radio receiption wasn't that great -- due to the relative low sensitivity. Wouldn't recommand it.
