Samsung UE49KU6670


The sound seemed good when I turned it on :)

Screen was either cracked in box or during assembly. Either way it seems the large curved TVs can break quite easily. I swapped for a flat one and will be going with flat from now on. I'm sure it's amazing if this doesn't happen to you, but this is...
