Instruct: Classify Amazon reviews into positive or negative sentiment
Query: It is good only for 2 years

Then the nasty intermittent loss-of-sound problem hit me.I was thinking it was due to loose connection, overheating/overloading, until I checked again here on Amazon. I am NOT alone...When I bought this piece of junk, the overall review was good. I bet next time I will only buy a "mature" model -- i.e. existing on the market over 2 years, so old customers can tell if the product can last.That is my $200 lesson.My hookup: Polk Monitor 50 x 2; Polk PSW 10; Samsung DLP 50''.
