Input: I am not sure which is worse - the poor performance or poor design of Sony's product. My unit has been plagued with problems since day one: the DVD tray would repeatedly reject either brand new DVDs or even my old ones, when first put in. After hours on their customer service, Sony, they finally came up w/ a workaround for this issue, but required me to go through three more rounds of emails before Sony agreed to ship out one replacement unit.
Output:
Bad review
