Query: Even at $159, it's not worth it.

This unit should be a simple (but effective) AV switcher box.If it worked as advertised, it would be a welcome 5-star solution for many a household.However, ours has never functioned properly from day one.The picture still cuts out randomly, while the audio continues.This is a problem that is well documented with these units. We chose to buy one anyway, because we couldn't find a similar unit in this price range. We were warned and we proceeded anyway.Now we're seriously shopping for a REAL replacement. We'll pay more, if necessary. In the end, the inexpensive $159 price tag is irrelevant. It's inexpensive price will quickly become insignificant, when the picture keeps cutting out during movies, concerts etc.I never write reviews. However, this unit has been so reliably unreliable, that I felt compelled. You've been warned.
