Initially I was a bit skeptical from the low prices. Previously, I had a 100-SAMSUNG HTQ 2.1 which was about 5 years old, who was very beautiful but whose reliability was poor (NO-DISC) without stopping, a more than mediocre with connections between HP and readers very bad. Printing on SONY is very good: the sound is very decent (in a room of about 45m²), it is impossible to turn the sound up because we do not would endure it but it means that it leaves room. .. especially since the sound does not deteriorate when it increases. Installation is easy and very good connections. One small problem: it puts a little time to start but no more than my previous. I still have to test different functions at ports and wireless ... For now, very satisfied with my purchase and delivery amazon but there are never any surprises at this level
